How do I read the number of files in a folder using Python? -

how read number of files in specific folder using python? example code awesome!

to count files , directories non-recursively can use os.listdir , take length.

to count files , directories recursively can use os.walk iterate on files , subdirectories in directory.

if want count files not directories can use os.listdir , os.path.file check if each entry file:

import os.path path = '.' num_files = len([f f in os.listdir(path)                 if os.path.isfile(os.path.join(path, f))])

or alternatively using generator:

num_files = sum(os.path.isfile(os.path.join(path, f)) f in os.listdir(path))

or can use os.walk follows:

len(os.walk(path).next()[2])

i found of these ideas this thread.
