How to do it...

The steps for this recipe are as follows:

1. The os.walk function in the os module is meant to traverse a directory recursively, its usage is not immediate, but with little effort, we can wrap it into a convenient generator of all the contained files:

import os

def traverse(path):
    for basepath, directories, files in os.walk(path):
        for f in files:
            yield os.path.join(basepath, f)

2. Then, we can just iterate over traverse and apply whatever operation we need on top of it:

for f in traverse('.'):
    print(f)
