python - Why not os.path.join use os.path.sep or os.sep?

Question

As we know, windows accept both "" and "/" as separator. But in python, "" is used. For example, call os.path.join("foo","bar"), 'foo\bar' will be returned. What's annoying is that there's an escape character, so you cannot just copy the path string and paste to your explorer location bar.

I wonder is there any way to make python use "/" as default separator, I've tried change the value of os.path.sep and os.sep to "/", but os.path.join still use "".

what's the right way?

PS:

I just don't understand why python is using "" as default separator on windows, maybe old version of windows don't support "/"?

Answer 1

To answer your question as simply as possible, just use posixpath instead of os.path.

So instead of:

from os.path import join
join('foo', 'bar')
# will give you either 'foo/bar' or 'foo\bar' depending on your OS

Use:

from posixpath import join
join('foo', 'bar')
# will always give you 'foo/bar'
