Python, add trailing slash to directory string, os independently

Question

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

Answer 1

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.

Answer 2

os.path.normpath(mypath) + os.sep

Answer 3

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

Answer 4

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)
