How can I iterate over files in a given directory?

Question

I need to iterate through all .asm files inside a given directory and do some actions on them.

How can this be done in a efficient way?

I really like using the scandir directive that is built into the os library. Here is a working example:

import os

i = 0
with os.scandir('/usr/local/bin') as root_dir:
    for path in root_dir:
        if path.is_file():
            i += 1
            print(f"Full path is: {path} and just the name is: {path.name}")
print(f"{i} files scanned successfully.")
