Recursively compare two directories to ensure they have the same files and subdirectories

Question

From what I observe filecmp.dircmp is recursive, but inadequate for my needs, at least in py2. I want to compare two directories and all their contained files. Do

Answer 1

This will check if files are in the same locations and if their content is the same. It will not correctly validate for empty subfolders.

import filecmp
import glob
import os

path_1 = '.'
path_2 = '.'

def folders_equal(f1, f2):
    file_pairs = list(zip(
        [x for x in glob.iglob(os.path.join(f1, '**'), recursive=True) if os.path.isfile(x)],
        [x for x in glob.iglob(os.path.join(f2, '**'), recursive=True) if os.path.isfile(x)]
    ))

    locations_equal = any([os.path.relpath(x, f1) == os.path.relpath(y, f2) for x, y in file_pairs])
    files_equal = all([filecmp.cmp(*x) for x in file_pairs]) 

    return locations_equal and files_equal

folders_equal(path_1, path_2)
