如何在路径的上下文中使用波浪号?

How do I use the tilde character in the context of paths?

这是在Python中.我使用 os.path.expanduser(' 〜/path/in/home/area').

This is in Python. I fixed the problem, using os.path.expanduser('~/path/in/home/area').

推荐答案

它是您在UNIX中的$HOME变量，通常是/home/username.

it is your $HOME var in UNIX, which usually is /home/username.

您的家"是指正在执行cd ~/MyDocuments/之类的命令的用户的家是cd /home/user_executing_cd_commnd/MyDocuments

"Your home" meaning the home of the user who's executing a command like cd ~/MyDocuments/ is cd /home/user_executing_cd_commnd/MyDocuments
