How to use glob() to find files recursively?

by

pathlib.Path.rglob

Use pathlib.Path.rglob from the the pathlib module, which was introduced in Python 3.5.

from pathlib import Path

for path in Path('src').rglob('*.c'):
    print(path.name)

If you don’t want to use pathlib, use can use glob.glob('**/*.c'), but don’t forget to pass in the recursive keyword parameter and it will use inordinate amount of time on large directories.

For cases where matching files beginning with a dot (.); like files in the current directory or hidden files on Unix based system, use the os.walk solution below.

os.walk

For older Python versions, use os.walk to recursively walk a directory and fnmatch.filter to match against a simple expression:

import fnmatch
import os

matches = []
for root, dirnames, filenames in os.walk('src'):
    for filename in fnmatch.filter(filenames, '*.c'):
        matches.append(os.path.join(root, filename))
