mkdir -p functionality in Python [duplicate]

Answer 1

mkdir -p gives you an error if the file already exists:

$ touch /tmp/foo
$ mkdir -p /tmp/foo
mkdir: cannot create directory `/tmp/foo': File exists

So a refinement to the previous suggestions would be to re-raise the exception if os.path.isdir returns False (when checking for errno.EEXIST).

(Update) See also this highly similar question; I agree with the accepted answer (and caveats) except I would recommend os.path.isdir instead of os.path.exists.

(Update) Per a suggestion in the comments, the full function would look like:

import os
def mkdirp(directory):
    if not os.path.isdir(directory):
        os.makedirs(directory)
