How to use glob() to find files recursively?

pathlib.Path.rglob

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

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

Similar to other solutions, but using fnmatch.fnmatch instead of glob, since os.walk already listed the filenames:

import os, fnmatchdef find_files(directory, pattern):    for root, dirs, files in os.walk(directory):        for basename in files:            if fnmatch.fnmatch(basename, pattern):                filename = os.path.join(root, basename)                yield filenamefor filename in find_files('src', '*.c'):    print 'Found C source:', filename

Also, using a generator alows you to process each file as it is found, instead of finding all the files and then processing them.

I've modified the glob module to support ** for recursive globbing, e.g:

>>> import glob2>>> all_header_files = glob2.glob('src/**/*.c')

Useful when you want to provide your users with the ability to use the ** syntax, and thus os.walk() alone is not good enough.
