How to convert ~/. path to absolute path

问题:

I have the following file: ~/.config.txt which is located in /root/.config. In order to avoid hardcoded paths in my Python file, how can I always replace (and correctly refer) to a ~/ path as <home> in Python? This way I could replace ~/.config.txt by /root/.config if /root/ was my home directory?

回答1:

You can use os.path.expanduser to convert ~ into your home directory:

>>> import os
>>> os.path.expanduser('~/.config.txt')
'/root/.config.txt'
>>>

This works on both *nix and Windows systems.
