how to cycle through os directory python code example

Example 1: iterate through all files in directory python

import os
directory = 'the/directory/you/want/to/use'

for filename in os.listdir(directory):
    if filename.endswith(".txt"):
      #do smth
      continue
    else:
    continue

Example 2: python loop through files in directory

import os

for filename in os.listdir(directory):
    if filename.endswith(".asm") or filename.endswith(".py"): 
         # print(os.path.join(directory, filename))
        continue
    else:
        continue

Example 3: traverse files in directory python

# python 3
import os

for dirpath, dirnames, filenames in os.walk(dir_path):
    print(dirpath)
    print(dirnames)
    print(filenames)
    
# python 2
import os.path

def print_it(x, dir_name, files):
    print(dir_name)
    print(files)

os.path.walk(your_dir, print_it, 0)
