I mentioned in my last post how useful Ben Welsh's code recipe's are. Count this post as my effort to encourage the practice among coding journalists.
Since launching the NewsHour's Annotated State of the Union, I've gotten a few questions about how it worked, particularly about linking comments to paragraphs. What's n... |
Asynchronous Programming in Python
Twisted is pretty good. It sits as one of the top networking libraries in Python, and with good reason. It is properly asynchronous, flexible, and mature. But it also has some pretty serious flaws that make it harder than necessary for programmers to use.
This hinders adoption of Twis... |
I'm trying to write a Python script that will crawl through a directory and find all files that are duplicates and report back the duplicates. What's the best was to solve this?
import os, sys
def crawlDirectories(directoryToCrawl):
crawledDirectory = [os.path.join(path, subname) for path, dirnames, filenames in os... |
I'd like to split a string using one or more separator characters.
E.g. "a b.c", split on " " and "." would give the list ["a", "b", "c"].
At the moment, I can't see anything in the standard library to do this, and my own attempts are a bit clumsy. E.g.
def my_split(string, split_chars):
if isinstance(string_L, bas... |

I wrote a spider, that worked brilliantly the first time. The second time I tried to run it, it didn't venture beyond the start_urls. I tried to fetch the url in scrapy shell and create a HtmlXPathSelector object from the returned response. That is when I got the error
So the steps were: `

Maybe a bit of example code will help: Notice the difference in the call signatures of
class A(object):
def foo(self,x):
print "executing foo(%s,%s)"%(self,x)
