urllib库安装
先切换到pip所在目录
D:Program FilesJetBrainsPyCharm 2017.3.3untitled>cd /d c:
c:>cd c:UsersceshiAppDataLocalProgramsPythonPython36Scripts
执行下载安装指令【哦 这里装了个exe打包工具 要装urllib的话 直接把名字改了就成
c:UsersceshiAppDataLocalProgramsPythonPython36Scripts>pip install Pyinstaller
以下是打包exe的，与urllib无关
c:UsersceshiAppDataLocalProgramsPythonPython36Scripts>pyinstaller.exe -F d:pytestgai.py

要被这节课搞疯 python2和python3的鸿沟 对于刚入门的小辣鸡来说实在是。。 心疼自己(ಥ_ಥ)

绕得晕乎乎。。 最近转做发行运营公司的测试。 感觉原本仅存的脑子也被吃掉了 写在小本本上背吧。。
在左边有一个Python代码片段列表，右面是他们的解释
class X(Y)：创建一个叫X的类，并继承Y
class X(object): def __init__(self, J)：类X有一个__init__方法，该方法有self和J两个参数
class X(object): def M(self, J)：类X有一个叫M的函数，该函数有self和J两个参数
foo = X()：给foo赋值为类X的一个实例
foo.M(J)：从foo里调用M函数，传递的参数为self和J
foo.K = Q：从foo里调用K属性，并将其设置为Q。
