How to handle double “~” in Python path?
The user input a path, so in Unix, he/she may enter ~/../../~. And I want Python to convert that to a absolute path. How to do that? The os.path.expanduser() can only expand the first ~, but not the following ones ~
So you will only get os.path.expanduser(~/../../~) = /Users/somebody/../../~
Thanks

Bash also only expands~if it's the first character in the path, just likeos.path.expanduser()

That's how tilde expansion is supposed to work. Even the shell wouldn't expand the second ~; tilde expansion only happens at the front of a path. See the POSIX spec or the bash manual.
os.path.expanduser is fine.

See user2357112's answer; they are by no means wrong. However, if you really insist on having it done this way:
import os
path = '~/foo/bar/~'
home_path = os.path.expanduser('~')
path = path.replace("~", home_path.lstrip('/')
