Python, add trailing slash to directory string, os independently

开发者_如何学运维

How can I add a trailing slash (/ for *nix, \ for win32) to a directory string, if the tailing slash is not already there? Thanks!

os.path.join(path, '') will add the trailing slash if it's not already there.

You can do os.path.join(path, '', '') or os.path.join(path_with_a_trailing_slash, '') and you will still only get one trailing slash.

Since you want to connect a directory and a filename, use

os.path.join(directory, filename)

If you want to get rid of .\..\..\blah\ paths, use

os.path.join(os.path.normpath(directory), filename)

You can do it manually by:

path = ...

import os
if not path.endswith(os.path.sep):
    path += os.path.sep

However, it is usually much cleaner to use os.path.join.

You could use something like this:

os.path.normcase(path)
    Normalize the case of a pathname. On Unix and Mac OS X, this returns the path unchanged; on case-insensitive filesystems, it converts the path to lowercase. On Windows, it also converts forward slashes to backward slashes.

Else you could look for something else on this page
