Question

The script is basically creating a list with all the files in all directories. Any idea why is seems to crash when it has to scan a directory that is larger than a few files?

import os

correctlyNamedDirectories = []

def crawlDirectories(directory):
    for dirname, dirnames, filenames in os.walk(directory):
        for subdirname in dirnames:
            correctlyNamedDirectories.append(os.path.join(dirname, subdirname))
        for filename in filenames:
            correctlyNamedDirectories.append(os.path.join(dirname, filename))

crawlDirectories('.')

print correctlyNamedDirectories

Also, is there a cleaner way of writing this?

Answer 1

Shorter method with a list comprehension:

correctlyNamedDirectories = [os.path.join(path, subname) for path, dirnames, filenames in os.walk(directory) for subname in dirnames + filenames]
