Error: Could not find or load main class : <p>I am new to java and I am currently trying to run a program for a class assignment and it compiles however, every time I run it I get this error "Error: Could not find or load main class sailboat.java" To make things worse I need to submit this in a different way from standard assignments logging onto the main server of my campus and transfer it from my directory to another yet every time I do it, it tells me it can't open the source file.</p>
<p>Would these two situations because by the same thing? Is this something caused by a mistake in my code, or is it something wrong with my Classpath?</p>
<p>here's the code I made, I used notepad++ </p>

Google Maps not loading after publishing on play store even after updating SHA 1 fingerprint for release key : <p>A newbie here to google maps api and android app development.
I am facing some strange issue and struggling with this from two days. I have developed an app in which I have used Google maps. I have launched the app to play store. The google map loads perfectly fine when I install the signed apk directly to mobile but not when I install through play store.</p>
<p>I have updated google maps api console with release key SHA 1 fingerprint. I am not able to find any solutions online also and did not get any support from google support team also. Somebody please help!</p>

Webpack output is empty object : <p>I want to build a react component library as a node module to then import it into different projects. But if I try to import a component it just returns an empty object.</p>
<p>button.jsx:</p>
<pre><code>import React, {Component} from 'react'
export class Button extends Component {
render() {
return <button className='btn'>Hello Button comp</button>
}

module.exports = {
Button: Button
}
</code></pre>
<p>webpack.config.js</p>
<pre><code>const Path = require('path');
module.exports = {
resolve: {

},
entry: {

}
]
}
}
</code></pre>
<p>Main property in package.json is bundle.js</p>
<p>I figured out that when I import Button in a project it is just an empty object. It seems to me as if webpack doesn't bundle the index file properly. Any ideas what could be wrong here?</p>

boto3: Spot Instance Creation : <p>I'm trying to create a spot instance using boto3.

<pre><code>botocore.exceptions.ClientError: An error occurred (InvalidParameterValue) when calling the RequestSpotInstances operation: Value () for parameter groupId is invalid. The value cannot be empty

Why does AWS Lambda function always time out? : <p>I am testing out aws lambda, using nodejs with the 4.3 version. I'm able to successfully complete all the statements in my handler function within the console test, which includes connecting to a mongodb host within our vpc. But, the function always times out. I've found several posts and resources that discuss using the callback, and setting properties on the context, and IAM role permissions, but no matter what I do, it always ends up timing out. Current code:</p>
<pre><code>'use strict';
var Mongoose = require('mongoose');
var Device = require('./device_model');
var Alarm = require('./alarm_model');
var Event = require('./event_model');
var mongoConnection = process.env.MONGO_URL;
var connection = Mongoose.connect(mongoConnection);
Mongoose.connection.once('open', function() {
console.log("Connecting to mongo at: " + mongoConnection);
console.log("Mongoose connection in lambda opened");
});
Mongoose.connection.on('error', function(){
console.error("Error creating mongoose connection in lambda, exiting!");
process.exit(1);
});
exports.check_alarms = function(event, context, callback) {
context.callbackWaitsForEmtpyEventLoop = false;
console.log("The incoming event: " + JSON.stringify(event));
var device = null;
Device.findByUUID(event.uuid, function(error, result){
if(!error){
device = result;
console.log("the device: " + JSON.stringify(device));
if(event.Ale && event.Ale.length > 0) {
console.log("We have an alarm, checking if already set");
callback(null, {"status":"alarms"});
} else {
console.log("Event contains no alarm; checking for historic active");
callback(null, {"status":"no alarms"});
}
} else {
console.log("there's a problem on mongo");
callback("problem", "status not so good");
}
});
callback(null, {"status":"outside of device find block"});
}

How to declare multiple dimensional array in TypeScript : In my app, I need to define an element like:
commandsList:[RegExp, string, string];
but when I tried to push the array elements into it, as below:
public registerCommand(command:RegExp, cb:string, phrase:string):void{
this.commandsList.push({ command: command, callback: cb, originalPhrase: phrase });
}
I got the below error at the `command:command`
> [ts] Argument of type '{ command: RegExp; callback: string;
> originalPhrase: string; }' is not assignable to parameter of type
> 'string | RegExp'. Object literal may only specify known properties,
> and 'command' does not exist in type 'string | RegExp'. (parameter)
> command: RegExp

c# don't understand calling methods. object orientated programming : I've just started object orientated programming and i don't quite understand how to call another method. I wanted to calculate the percentage increase and then put out the resulting overall price. This would be done by calling the method to do the working out then returning the value to the other method. However i'm unsure about how to cross over between methods.
Could someone please explain how i'm meant to do this. Preferably not just giving the answer so i can fully understand what's happening.
p.s. this piece of code is in a class called RetailPricing. As i've copied and pasted it, it doesn't look like it's all formatted properly. (i understand how to call this class to the main program)
Thank you in advance!

class RetailPricing
{
public void CalculateRetailPrice()
{
double inputcost;
double inputpercent;
string inputitemcost;
string inputmarkup;
Console.Write("Please Input The Cost Of The Item: ");
inputitemcost = Console.ReadLine();
inputcost = double.Parse(inputitemcost);
Console.Write("Please Input The Markup Percentage: ");
inputmarkup = Console.ReadLine();
inputpercent = double.Parse(inputmarkup);
Console.Write("Your Retail Price Is: " + newprice);
}
public double sum(double MarkUpPercentage, double overallprice, double newprice)
{
MarkUpPercentage = inputpercent + 100;
overallprice = MarkUpPercentage / 100;
newprice = inputcost * overallprice;
return newprice;

Can you run a macro from one excel sheet in another? Xlwings : I want to run a macro on CSV files that are sent to me using an xlwings script. As such storing the Macro in each new file would be a pain. Is there anyway to run the scrip from another workbook, or even just directly send the code to the CSV file?

Not able to comment, android developers please read! WebView display : since i don't have the 50 rep required to comment -.- stupid idea...
This is my first app development so please bare with me on this ^^.
ill simply have to ask this question here again, it's topic related to this: https://stackoverflow.com/questions/14423981/android-webview-display-only-some-part-of-website/14424866#14424866
and it's about this code that is written there:
public class MyWebClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, String url) {
view.loadUrl("javascript:your javascript");
}
}
.........
final MyWebClient myWebViewClient = new MyWebClient();
mWebView.setWebViewClient(myWebViewClient);
Im having difficulties running this code even after modified like this:
public class MyWebClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
webView.loadUrl("http://tid.mspot.nu");
return true;
}
@Override
public void onPageFinished(WebView view, String url) {
view.loadUrl("document.getElementsByClassName('white').style.visibility = 'hidden'");
}
}
final MyWebClient myWebViewClient = new MyWebClient();
mWebView.setWebViewClient(myWebViewClient);

and i would love to be able to implement that feature of hiding this "btn_white" class i know it's supposed to be an id which ill change right now. This is just a button to download the app that i wan't to hide in the app, makes sense i suppose ^^
would love to have some help with this since it's my first time developing anything for android. Thanks!

Pandas - Slice Large Dataframe in Chunks : <p>I have a large dataframe (>3MM rows) that I'm trying to pass through a function (the one below is largely simplified), and I keep getting a <code>Memory Error</code> message. </p>
<p>I think I'm passing too large of a dataframe into the function, so I'm trying to:</p>
<p>1) Slice the dataframe into smaller chunks <strong>(preferably sliced by <code>AcctName</code>)</strong></p>
<p>2) Pass the dataframe into the function</p>
<p>3) Concatenate the dataframes back into one large dataframe</p>

df['Double_Transaction'] = df['Transaction'] * 2

GHI 12/1 14.33
GHI 12/6 21.99
GHI 12/12 98.81
</code></pre>
<p>I know that my function works properly, since it will work on a smaller dataframe (e.g. 40,000 rows). I tried the following, but I was unsuccessful with concatenating the small dataframes back into one large dataframe.</p>
<pre><code>def split_df(df):
new_df = []
AcctNames = df.AcctName.unique()
DataFrameDict = {elem: pd.DataFrame for elem in AcctNames}
key_list = [k for k in DataFrameDict.keys()]
new_df = []
for key in DataFrameDict.keys():
DataFrameDict[key] = df[:][df.AcctNames == key]
trans_times_2(DataFrameDict[key])

How to traverse a treeview in WPF and get values from all nodes : Okay, I'm ready for the downvotes and the snide comments but I can't find an answer to this question now matter how I ask it. There appears to be solutions if the treeview is in WinForms but not if it's in WPF.
I'm loading an XML file at runtime that is bound to a treeview called OOB. The user can perform all kinds of edits to the treeview (adding and deleting nodes, changing the node's contents, etc.). All of this works perfectly. Now, I have to save it back out as an XML file. Apparently, this is near impossible in WPF.
At this point all I can think of doing is traversing the entire tree (from what I've read it may be necessary to first expand all nodes which is easily enough done) and then I can, one by one, read the nodes and write them to an XML file using `xmlWriter`.
So, unless somebody has a better idea, how can I in C# and WPF traverse an entire tree, getting the contents of each `Node.name`? Once I have the contents of each node I should be able to reconstitute the tree structure and write them out as an XML file.
Thanks in advance!

I am wanting to send a command after the button is clicked to the server where a C# script running the motors will pick up the message and then control the motors accordingly. Would the best way to do this be through JSON and/or Jquery?
So far I have a .load function written in jquery that is sending a simple message to ther server then that function is being called upon button press by the html document. My main question is if this is the most best route to go when communicating between HTML, a server, and C#. Thank you.

Hooks and Redux Saga : <p>I am learning redux hooks and wondering how to use it along with redux saga.</p>
<p>Currently the code written in saga is as follows.</p>
<blockquote>
<p>centers.js</p>
</blockquote>
<pre><code>componentDidMount() {
this.props.getCenters();
}
...
<tbody>
{
this.props.centers ?
<React.Fragment>
{
centers.map((center, index) =>
<tr key={index}>
<td>{center.name}</td>
<td>{center.zip}</td>
</tr>
)
}
</React.Fragment>
:
<tr>
<td> No data available</td>
</tr>
}
</tbody>
</code></pre>
<p>The actions file is defined as follows.</p>
<pre><code>export const getCenters = () => ({
type: types.CENTERS_REQUEST,
});
</code></pre>
<p>The saga file is defined as follows.</p>
<pre><code>import { DEFAULT_ERROR_MSG } from '../../constants';
import { instance as centerProvider } from '../services/centerProvider';
function* fetchCenters() {
try {
const response = yield call(centerProvider.getCenters);
const centers = response.data.data.centers;
// dispatch a success action to the store
yield put({ type: types.CENTERS_SUCCESS, centers});
} catch (error) {
// dispatch a failure action to the store with the error
yield put(DEFAULT_ERROR_MSG);
}
}
export function* watchCenterRequest() {
yield takeLatest(types.CENTERS_REQUEST, fetchCenters);
}
export default function* centerSaga() {
yield all([
watchCenterRequest()
]);
}
</code></pre>
<p>So the question is,</p>
<ul>
<li>Do we still need redux if we use hooks?</li>
<li>How can we rewrite the above code using hooks?</li>
</ul>

convert Java to Json Array please assist : I have to convert an Arraylist of users to from java to Json
I figured out how to get the
user to convert I don't know how to use the syntax for the array
This is in the driver:
// Convert a User to JSON
String testStr = JsonUserConverter.convertUserToJson(bob);
System.out.println(testStr);
// Convert JSON string to a User
User testUser = JsonUserConverter.convertJsonToUser(jsonUserString);
System.out.println(testUser);
// Convert an ArrayList of Users to JSON
and I have to populate this
public static String convertUsersArrayToJson(ArrayList<User>users){}
with my User data from my User class. I only just learned about ObjectMapper. I assume there's something in my library to convert but I don't know. Help.

Vue + Laravel: How to properly download a PDF file? : <p><strong>THE SITUATION:</strong></p>
<p>Frontend: Vue. Backend: Laravel.</p>
<p>Inside the web app I need to let the user download certain pdf files:</p>
<ul>
<li>I need Laravel to take the file and return it as a response of an API GET request.</li>
<li>Then inside my Vue web app I need to get the file and download it.</li>
</ul>
<p><strong>THE CODE:</strong></p>
<p><strong>API:</strong></p>
<pre><code>$file = public_path() . "/path/test.pdf";
$headers = [
'Content-Type' => 'application/pdf',
];
return response()->download($file, 'test.pdf', $headers);
</code></pre>
<p><strong>Web app:</strong></p>
<pre><code>downloadFile() {
this.$http.get(this.apiPath + '/download_pdf')
.then(response => {
let blob = new Blob([response.data], { type: 'application/pdf' })
let link = document.createElement('a')
link.href = window.URL.createObjectURL(blob)
link.download = 'test.pdf'
link.click()
})
}
</code></pre>
<p><strong>OUTCOME:</strong></p>
<p>Using this code I do manage to download a pdf file. The problem is that the pdf is blank. </p>
<p>Somehow the data got corrupted (not a problem of this particular pdf file, I have tried with several pdf files - same outcome)</p>
<p><strong>RESPONSE FROM SERVER:</strong></p>
<p>The response itself from the server is fine:</p>
<p><a href="https://i.stack.imgur.com/E0nCJ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/E0nCJ.png" alt="enter image description here"></a></p>
<p><strong>PDF:</strong></p>
<p>The problem may be with the pdf file. It definitely looks corrupted data. This is an excerpt of how it looks like the <code>response.data</code>:</p>
<p><a href="https://i.stack.imgur.com/0F2OW.png" rel="noreferrer"><img src="https://i.stack.imgur.com/0F2OW.png" alt="enter image description here"></a></p>
<p><strong>THE QUESTION:</strong></p>
<p>How can I properly download a pdf file using Laravel for the API and Vue for the web app?</p>

Reversing the order of a linked-list FORTRAN (gen_ll.f90) : I've recently adopted the use of linked lists in FORTRAN and after some reading decided to use the [gen_ll.f90 package][1] from the [FORTRAN WIKI][2] which seemed simple and sufficient to my needs.
It was only later that I realized that I must reverse the order of the terms in the list (i.e. 1->2->3->...->N->NULL needs to be N->...->3->2->1->NULL).
I was trying to generate a function which replaces the pointers %P%Next to the previous instead of the next. The logic seemed good, but I keep messing it up somehow.
I would ask for your help with coding this small function.
The source code is attached in the [gen_ll.f90][1] link and the function/subroutine is straight-forward.
Thank you so much!

Can Spring Data REST's QueryDSL integration be used to perform more complex queries? : <p>I'm currently building a REST API in which I want clients to easily filter on most properties of a specific entity. Using <a href="http://querydsl.com/" rel="noreferrer">QueryDSL</a> in combination with <a href="http://projects.spring.io/spring-data-rest/" rel="noreferrer">Spring Data REST</a> (<a href="https://gist.github.com/olivergierke/decf03d4948cd58a51bc" rel="noreferrer">an example by Oliver Gierke</a>) allows me to easily get to 90% of what I want by allowing clients to filter by combining query parameters which refer to properties (e.g. <code>/users?firstName=Dennis&lastName=Laumen</code>).</p>
<p>I can even customize the mapping between the query parameters and an entity's properties by implementing the <code>QuerydslBinderCustomizer</code> interface (e.g. for case insensitive searches or partial string matches). This is all great, however I also want the clients to be able to filter some types using ranges. For example with regards to a property like date of birth I'd like to do something like the following, <code>/users?dateOfBirthFrom=1981-1-1&dateOfBirthTo=1981-12-31</code>. The same goes for number based properties, <code>/users?idFrom=100&idTo=200</code>. I have the feeling this should be possible using the <code>QuerydslBinderCustomizer</code> interface but the integration between these two libraries isn't documented very extensively.</p>
<p><strong><em>Concluding, is this possible using Spring Data REST and QueryDSL? If so, how?</em></strong></p>

how to keep spaces with escape sequences stringbuilder c# : I have a `stringbuilder` setup with escape sequences to show a ASCII like art to text. Here is my code:
sb.AppendLine(@" _____ ______ ___ ___ ________ ");
sb.AppendLine(@" |\ _ \ _ \|\ \|\ \|\ ___ \ ");
sb.AppendLine(@" \ \ \\\__\ \ \ \ \\\ \ \ \_|\ \ ");
sb.AppendLine(@" \ \ \\|__| \ \ \ \\\ \ \ \ \\ \ ");
sb.AppendLine(@" \ \ \ \ \ \ \ \\\ \ \ \_\\ \ ");
sb.AppendLine(@" \ \__\ \ \__\ \_______\ \_______\ ");
sb.AppendLine(@" \|__| \|__|\|_______|\|_______| ");
sb.AppendLine(@" ");
And here is the output:
_____ ______ ___ ___ ________
|\ _ \ _ \|\ \|\ \|\ ___ \
\ \ \\\__\ \ \ \ \\\ \ \ \_|\ \
\ \ \\|__| \ \ \ \\\ \ \ \ \\ \
\ \ \ \ \ \ \ \\\ \ \ \_\\ \
\ \__\ \ \__\ \_______\ \_______\
\|__| \|__|\|_______|\|_______|
How can I keep my strings just as I typed them?

NLTK: corpus-level bleu vs sentence-level BLEU score : <p>I have imported nltk in python to calculate BLEU Score on Ubuntu. I understand how sentence-level BLEU score works, but I don't understand how corpus-level BLEU score work.</p>
<p>Below is my code for corpus-level BLEU score:</p>
<pre><code>import nltk
hypothesis = ['This', 'is', 'cat']
reference = ['This', 'is', 'a', 'cat']
BLEUscore = nltk.translate.bleu_score.corpus_bleu([reference], [hypothesis], weights = [1])
print(BLEUscore)
</code></pre>
<p>For some reason, the bleu score is 0 for the above code. I was expecting a corpus-level BLEU score of at least 0.5.</p>
<p>Here is my code for sentence-level BLEU score</p>
<pre><code>import nltk
hypothesis = ['This', 'is', 'cat']
reference = ['This', 'is', 'a', 'cat']
BLEUscore = nltk.translate.bleu_score.sentence_bleu([reference], hypothesis, weights = [1])
print(BLEUscore)
</code></pre>
<p>Here the sentence-level BLEU score is 0.71 which I expect, taking into account the brevity-penalty and the missing word "a". However, I don't understand how corpus-level BLEU score work.</p>
<p>Any help would be appreciated.</p>

Is it possible to map only a portion of an array? (Array.map()) : <p>I am building a project using React.js as a front-end framework. On one particular page I am displaying a full data set to the user. I have an Array which contains this full data set. It is an array of JSON objects. In terms of presenting this data to the user, I currently have it displaying the whole data set by returning each item of data using Array.map().</p>
<p>This is a step in the right direction, but now I need to display only a portion of the data-set, not the whole thing, I also want some control in terms of knowing how much of the total data set has been displayed, and how much of the data set is yet to be displayed. Basically I am building something like a "view more" button that loads more items of data to the user. </p>
<p>Here is what I am using now where 'feed' represents my Array of JSON objects. (this displays the whole data set.)</p>
<pre><code> return (
<div className={feedClass}>
{
feed.map((item, index) => {
return <FeedItem key={index} data={item}/>
})
}
</div>
);
</code></pre>
<p>I am wondering if it is possible to use .map() on only a portion of the array without having to break up the array before hand? I know that a possible solution would be to hold the full data set, and break it off into portions, and then .map() those portions, but is there a way to .map() a portion of the array without having to break it up?</p>
<p>Any and all feedback is appreciated. Thanks!</p>

How to record a video in Selenium webdriver and Java API : <p>I have automated scripts that run every night (around 50 scripts or testcases). I want to record a video of each test case (Selenium Java API + Cucumber). Is there any tool or way that i can use to control video recording for each test case separately? I want during a test case setup start recording and during teardown stop recording and save the video locally with a specified name and date. So I should have 50 videos for each testcase (more preferably save only videos for the failed test cases)</p>
<p>Is there a way of integrating this functionality in the code I use for my setups and teardowns?</p>

How to verify users current password? : <p>So, maybe I missed this somewhere in the docs but I couldn't find anything of the sort. </p>

<p>Even if this might be somewhat secure I would rather have him type his old one to prevent people from going on already authenticated sessions from say family members or so and changing the pw. </p>
<p>Is there any way to do this?</p>

How to play streaming audio using pyglet? : <p>The goal of this question is trying to figure out how to play streaming audio using pyglet. The first is just making sure you're able to play mp3 files using pyglet, that's the purpose of this first snippet:</p>
<pre><code>import sys
import inspect
import requests
import pyglet
from pyglet.media import *
pyglet.lib.load_library('avbin')
pyglet.have_avbin = True
def url_to_filename(url):
return url.split('/')[-1]
def download_file(url, filename=None):
filename = filename or url_to_filename(url)
with open(filename, "wb") as f:
print("Downloading %s" % filename)
response = requests.get(url, stream=True)
total_length = response.headers.get('content-length')
if total_length is None:
f.write(response.content)
else:
dl = 0
total_length = int(total_length)
for data in response.iter_content(chunk_size=4096):
dl += len(data)
f.write(data)
done = int(50 * dl / total_length)
sys.stdout.write("\r[%s%s]" % ('=' * done, ' ' * (50 - done)))
sys.stdout.flush()
url = "https://freemusicarchive.org/file/music/ccCommunity/DASK/Abiogenesis/DASK_-_08_-_Protocell.mp3"
filename = "mcve.mp3"
download_file(url, filename)
music = pyglet.media.load(filename)
music.play()
pyglet.app.run()
</code></pre>
<p>If you've installed the libraries <code>pip install pyglet requests</code> and also installed <a href="https://avbin.github.io/AVbin/Download.html" rel="noreferrer">AVBin</a> at this point you should be able to listen the mp3 once it's been downloaded.</p>
<p>Once we've reached this point, I'd like to figure out how to play & buffering the file in a similar way to mostly of the existing web video/audio players using pyglet+requests. This means playing the files without waiting till the file has been downloaded completely.</p>
<p>After reading the pyglet media <a href="http://pyglet.readthedocs.io/en/pyglet-1.3-maintenance/modules/media.html#classes" rel="noreferrer">docs</a> you can see there are available these classes:</p>
<pre><code>media
sources
base
AudioData
AudioFormat
Source
SourceGroup
SourceInfo
StaticSource
StreamingSource
VideoFormat
player
Player
PlayerGroup

<p>That's why I've created a new question. How do you play streaming audio using pyglet? Could you provide a little example using the above mcve as a base?</p>

C# Overloaded Method does not use int imput : I'm trying to create console app to understand method overloading.
I got Class lib like this
namespace GetStringName
{
public class GetString
{
public void Player(double num)
{
double number = num * 2;
Console.Write(number);
}
public void Player(string name)
{
char[] charr = name.ToCharArray();
Array.Reverse(charr);
Console.Write(charr);
}
}
}
And I got my Console app like below
using GetStringName;
using System;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
GetString y = new GetString();
y.Player(Console.ReadLine());
Console.ReadLine();
}
}
}
And whatever I type (string or integer) it always does the revert string thing.
Can you please tell me what I'm doing wrong?

Is it true that the dimension of an array is determined the moment the array is created, and cannot be changed later on? : <pre><code>int main()
{
int a[3]={1,2,3};
int *b;
b=&a[10];
printf("%u\n",b);
printf("%d",*b);
}
</code></pre>
<p>I thought that the above program would give me an <strong>error</strong> as <code>a</code> is a collection of only <em>3 data items</em>, and <code>b=&a[10];</code> by this <code>b</code> stored the address of the <em>11th data member</em> of <code>a</code>. But in place of error it gives the address of 11th data member.</p>
<p>Size of the array is 3 and but it can store the variables beyond of its size! so how does it possible?</p>

what is the regular expressions in "R" that find all words that: Start with a letter1 and End with another letter2? : i'm trying to work out the exercise from a book called "R for data science" on regular expressions.
there's this question which i'm unable to solve :
1.Given the corpus of common words in stringr::words, create regular expressions that find all words that:
1.Start with “y”.
2.End with “x”
3.Have seven letters or more.
example :
sentence <- "i want to extract these - yandx,ynx and yrax,romanav "
#it would be helpful to find how to do these with stringr::str_view() function.
also please suggest me some good resources to refer for learning regex in r .

Multiple And condition in Where Clause in Sql : I have a table like this
ID Process Work
A1 | 0 | Done
A1 | 1 | Progress
A2 | 0 | Done
A2 | 1 | Done
A2 | 2 | Progress
A3 | 0 | Done
A3 | 1 | Done
A3 | 2 | Progress
I need to output ID of only that work whose Process=0 and Work=Done and if Process>0 and Work=Progress. Hence in this case it will output only A1 since for Process>0 A2 and A3 have Work=Done.
How do I use multiple And statements in where condition?

divide a string into two halves in python : <p>this is my question:</p>
<pre><code>F. front_back
# Consider dividing a string into two halves.
# If the length is even, the front and back halves are the same length.
# If the length is odd, we'll say that the extra char goes in the front half.
# e.g. 'abcde', the front half is 'abc', the back half 'de'.
# Given 2 strings, a and b, return a string of the form
# a-front + b-front + a-back + b-back
</code></pre>
<p>and this is my answer:</p>
<pre><code>def front_back(a, b):
s = ""
if len(a) % 2 == 0:
s = s + a[:len(a) / 2]
if len(b) % 2 == 0:
s = s + b[:len(b) / 2]
s = s + a[len(a) / 2:]
s = s + b[len(b) / 2:]
else:
s = s + b[:len(b) / 2 + 1]
s = s + a[len(a) / 2 + 1:]
s = s + b[len(b) / 2 + 1:]
else:
s = s + a[:len(a) / 2 + 1]
if len(b) % 2 == 0:
s = s + b[:len(b) / 2]
s = s + a[len(a) / 2:]
s = s + b[len(b) / 2:]
else:
s = s + b[:len(b) / 2 + 1]
s = s + a[len(a) / 2 + 1:]
s = s + b[len(b) / 2 + 1:]
return s
