You can use the command glob:

import glob, os
os.chdir("/mydir")
for file in glob.glob("*.txt"):
    print(file)

or simply os.listdir:

import os
for file in os.listdir("/mydir"):
    if file.endswith(".txt"):
        print(os.path.join("/mydir", file))

Alternatively, if you wish to walk through a directory, use os.walk:

import os
for root, dirs, files in os.walk("/mydir"):
    for file in files:
        if file.endswith(".txt"):
             print(os.path.join(root, file))

Use glob.

>>> import glob
>>> glob.glob('./*.txt')
['./outline.txt', './pip-log.txt', './test.txt', './testingvim.txt']

Something along those lines should suffice.

for root, dirs, files in os.walk(directory):
    for file in files:
        if file.endswith('.txt'):
            print(file)

Something along these lines will suffice:

>>> import os
>>> path = '/usr/share/cups/charmaps'
>>> text_files = [f for f in os.listdir(path) if f.endswith('.txt')]
>>> text_files
['euc-cn.txt', 'euc-jp.txt', 'euc-kr.txt', 'euc-tw.txt', ... 'windows-950.txt']

You may simply use pathlibs glob 1: to accomplish this.

import pathlib

list(pathlib.Path('your_directory').glob('*.txt'))

Alternatively, in a loop:

for txt_file in pathlib.Path('your_directory').glob('*.txt'):
    # do something with "txt_file"

You can use.glob(‘**/*.txt’) to make it recursive.

1In Python 3.4, the pathlib module was added to the standard library. However, back-ports of that module are available for older Python versions (through conda or pip): pathlib and pathlib2.
