文件命名导致的No module named ‘http.client‘错误

做一个小功能，用python命令行发送GET请求。

建了个目录，随手给程序文件命名成http.py

打开cmd命令，进入该目录，安装requests包，进入python命令行，进行测试。

敲入第一条命令：import requests，报错：

Traceback (most recent call last):
  File "", line 1, in
  File "c:\python37\lib\site-packages\requests\__init__.py", line 43, in
    import urllib3
  File "c:\python37\lib\site-packages\urllib3\__init__.py", line 11, in
    from . import exceptions
  File "c:\python37\lib\site-packages\urllib3\exceptions.py", line 3, in
    from .packages.six.moves.http_client import IncompleteRead as httplib_IncompleteRead
  File "c:\python37\lib\site-packages\urllib3\packages\six.py", line 199, in load_module
    mod = mod._resolve()
  File "c:\python37\lib\site-packages\urllib3\packages\six.py", line 113, in _resolve
    return _import_module(self.mod)
  File "c:\python37\lib\site-packages\urllib3\packages\six.py", line 82, in _import_module
    __import__(name)
ModuleNotFoundError: No module named 'http.client'; 'http' is not a package

按报错信息去搜索，遇到这问题的人还真不少，但没有什么好的解决办法。

有人说可能是http包有问题，突然看见自己建的http.py文件，突然明白了什么。把名字改了，一切正常。

看来给文件命名时，必须绕开一些关键词汇。
