snippet goes through two folders recursively and displays all files that have the same name, but are different and it lists all files that exist either on the left or right filepath:

compare_dir_contents.py

import filecmp
c = filecmp.dircmp(filepath1, filepath2)

def report_recursive(dcmp):
    for name in dcmp.diff_files:
        print("DIFF file %s found in %s and %s" % (name, 
            dcmp.left, dcmp.right))
    for name in dcmp.left_only:
        print("ONLY LEFT file %s found in %s" % (name, dcmp.left))
    for name in dcmp.right_only:
        print("ONLY RIGHT file %s found in %s" % (name, dcmp.right))
    for sub_dcmp in dcmp.subdirs.values():
        print_diff_files(sub_dcmp)

report_recursive(c)
