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

Question

Can someone tell me how to find all the files in directory with .txt extension in Python?

Answer 1

Their are many methods to do it:

• os.walk

 >>> import os

>>> path = '/user/Bluetooth/cramp/charm'
>>> text_files = [f for f in os.listdir(filedestination) if f.endswith('.txt')]
>>> text_files
['qwe-cn.txt', 'zxc-jp.txt', 'qwe-kr.txt', 'qwe-tw.txt', ... 'mac-10.txt']

Or 

• Glob 

>>> import glob
>>> glob.glob('./*.txt')
['./Maths.txt', './physics.txt', './chem.txt', './bio.txt']

Or fnmatch.filter()

 import fnmatch, os

print fnmatch.filter(os.listdir("/qwe"), "*.tx?") # 

Answer 2

You can use os.listdir() which returns a list containing all the names of the entries in the directory which is given by the path.

Syntax-

os.listdir(path)

Ex-

import os

for myfile in os.listdir("/mydict"):

   if file.endswith(".txt"):

       print(os.path.join("/mydict", myfile))

Hope this answer helps.
