This formula installs a python2 executable to /usr/local/bin.
If you wish to have this formula's python executable in your PATH then add
the following to ~/.zshrc:
  export PATH="/usr/local/opt/python/libexec/bin:$PATH"

  Pip and setuptools have been installed. To update them
    pip2 install --upgrade pip setuptools

    You can install Python packages with
      pip2 install <package>

      They will install into the site-package directory
        /usr/local/lib/python2.7/site-packages

	See: https://docs.brew.sh/Homebrew-and-Python.html

设置PATH

vim ~/.zshrc 加入
export PATH="/usr/local/opt/python/libexec/bin:$PATH"

验证PATH设置成功

输入which python
如果显示 /usr/local/opt/python/libexec/bin/python则说明成功

如何使用系统的python

如果有需要想使用一下系统的Python，输入/usr/bin/python即可
