How to find the real user home directory using Python?

在 macOS 的 python 裡直接輸入 ~/Documents/ 這個路徑，是無效的，檢查 path.exists 是 false. 解法：

import os
print(os.path.expanduser('~'))

You can also query the environment variables for the HOME variable −

import os
print(os.environ['HOME'])

If you’re on Python 3.4+, you can also use pathlib module to get the home directory. 

example

from pathlib import Path
print(Path.home())
