Find all files in a directory with extension .txt in Python

Answer 1

You can simply use pathlibs glob ¹:

import pathlib

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

or in a loop:

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

If you want it recursive you can use .glob('**/*.txt)

¹The pathlib module was included in the standard library in python 3.4. But you can install back-ports of that module even on older Python versions (i.e. using conda or pip): pathlib and pathlib2.
