mkdir -p functionality in Python [duplicate]

Answer 1

import os
from os.path import join as join_paths

def mk_dir_recursive(dir_path):

    if os.path.isdir(dir_path):
        return
    h, t = os.path.split(dir_path)  # head/tail
    if not os.path.isdir(h):
        mk_dir_recursive(h)

    new_path = join_paths(h, t)
    if not os.path.isdir(new_path):
        os.mkdir(new_path)

based on @Dave C's answer but with a bug fixed where part of the tree already exists
