演示Django版本为当前最新版本v2.2
当Django配置文件中的INSTALL_APPS包含了django.contrib.auth时，就默认启用了一个简单的权限系统，提供了为用户或组分配权限的方法
之所以说简单呢？主要是因为：

也就是说，假如有一个Blog表，我们可以赋予用户或组对Blog表有delete的权限，那么用户或组成员就可以删除全部Blog，是不能控制用户只能删除自己创建的blog的

然而很多名为开源掌机，实际上只是拿来玩模拟器游戏。
外观设计也很土味😜

可能是淘宝的推荐算法有所长进吧，偶然间发现一个叫GameShell的产品。

Is it intended behavior that hMailServer will not add the SpamAssassin score to its own score unless the SpamAssassin score is greater than or equal to the SpamAssassin spam threshold (i.e., SpamAssassin tags it as spam)?

How to make an unblocker
How to make an unblocker
I've seen a lot of unblockers out there, but none of them are mine so here's mine.
Concept
The basic concept of an unblocker is that we will utilize repl.it's virtual machine and their internet to provide not only an unblocker, but a vpn! (in california or smth)

Intro
All my spouse’s digital photo frames are either broken or nearly broken – probably she got them from garage sales. Regardless, they spend 99% of the the time black. Now, since I had bought that Raspberry Pi PiDisplay awhile back, and it is underutilized, and I know a thing or two about linux, I felt I could creat... |
So I ran my summarizer yesterday and it took literally all day to run only 200 products through the lex sum function. So I went through my code and added a timer for each major step in the process like so:
start = time.time()
asin_list = get_asins(limit)
end = time.time()
print('Get ASINs: ', end - start)
Turns out it... |
I have seen few py scripts which use this at the top of the script. In what cases one should use it?

概要
在 sklearn 包中，OneHotEncoder 函数非常实用，它可以实现将分类特征的每个元素转化为一个可以用来计算的值。本篇详细讲解该函数的用法，也可以参考官网 sklearn.preprocessing.OneHotEncoder。
解析
该函数在 sklearn.preprocessing 类中，格式为：
OneHotEncoder(n_values=’auto’, categorical_features=’all’, dtype=<class ‘numpy.float64’>, sparse=True, handle_unknown=’error’)
为了方便理解，我们先看下面一个例子：
