python - Get file size during os.walk -

-

i using os.walk compare 2 folders, , see if contain exact same files. however, checks file names. want ensure file sizes same, , if they're different report back. can file size os.walk?

the same way file size without using os.walk, os.stat. need remember join root:

for root, dirs, files in os.walk(some_directory):     fn in files:         path = os.path.join(root, fn)         size = os.stat(path).st_size # in bytes          # ...
