file - How to get all of the immediate subdirectories in Python

Question

I'm trying to write a simple Python script that will copy a index.tpl to index.html in all of the subdirectories (with a few exceptions).

I'm getting bogged down by trying to get the list of subdirectories.

Answer 1

import os
def get_immediate_subdirectories(a_dir):
    return [name for name in os.listdir(a_dir)
            if os.path.isdir(os.path.join(a_dir, name))]
