Directory-tree listing in Python

This is a way to traverse every file and directory in a directory tree:

import osfor dirname, dirnames, filenames in os.walk('.'):    # print path to all subdirectories first.    for subdirname in dirnames:        print(os.path.join(dirname, subdirname))    # print path to all filenames.    for filename in filenames:        print(os.path.join(dirname, filename))    # Advanced usage:    # editing the 'dirnames' list will stop os.walk() from recursing into there.    if '.git' in dirnames:        # don't go into any .git directories.        dirnames.remove('.git')

Here's a helper function I use quite often:

import osdef listdir_fullpath(d):    return [os.path.join(d, f) for f in os.listdir(d)]
