篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Python爬糗百热门20条并邮件分发+wxPython简易GUI+py2app转成可运行文件相关的知识，希望对你有一定的参考价值。
学了一阵子Python，拿来做个什么有意思的东西呢？爬糗百好了。爬到的内容，邮件分发出去。
然后又啃了两天的wxpython，做了个简易的邮件管理界面，能够在这里添加或者删除邮件，而且一键爬虫发送。
最后，索性封装成APP吧。又试了一把py2app。简单好用。
因为是让用户自行加入和删除邮箱。所以程序一定要兼顾到各种情况：比方输入的邮箱格式不合法。输入的邮箱里包括中文字符，分隔符不正确，删除了所有邮箱然后又要发邮件等问题。
首先是QiuBai.py：爬虫，正则匹配我们想要的内容。然后将内容稍作处理返回。

except Exception, e:
return str(e)最后，用wxpython做了个简易的收件人管理界面，Spider_QiuBai.py，实现：添加邮件、删除邮件、一键爬虫发送糗百热门20条到邮件列表。
当然，为了程序正确执行，会有各种验证，比方输入的邮箱格式是否合法，发送时检查receiver列表是否为空等
程序比較简单，代码例如以下：

if __name__ == "__main__":

app.MainLoop()
最后就是Python转APP了：
（1）在MAC终端里输入pip install py2app安装py2app
（2）创建setup.py，我的project位于/Users/Sophie/PycharmProjects/QiuBai，所以cd到这个路径下。然后vi setup.py。在这个文件中输入例如以下内容（提前准备个icns图标。放到project路径下）
"""
py2app build script for MyApplication
Usage:
python setup.py py2app
"""
from setuptools import setup
OPTIONS = {
‘iconfile‘:‘lemon.icns‘
}
setup(
app=["Spider_QiuBai.py"],
options={‘py2app‘: OPTIONS},
setup_requires=["py2app"],
)
（3）rm -rf build dist（假设反复多次打包的话。这个命令是须要的。第一次不须要）
（4）python setup.py py2app 用这个命令打包，打包好的app会存放在该路径下的dist路径下。我的例如以下：/Users/Sophie/PycharmProjects/QiuBai/dist
至此，这个小玩意儿已经做好了，当中略麻烦的可能就是正则还有界面了 Hope you enjoy it ^ ^
