Instead of writing our own recursive loops for traversing between directories and sub-directories python give us one interesting function in
OS module which makes our work very easy and in optimized way.
OS module has many other useful functions which helps us to right less code for simple tasks.
Below I have given a simple example for using
os.walk function, here we are trying to find the
.mp3 files available in the specified directory.
import os def search_for_files(path_search, extention): for dirname, dirnames, filenames in os.walk(path_search): for filename in filenames: if filename.endswith(extention): print os.path.join(dirname, filename) if __name__ == '__main__': search_for_files("/home/vinod/Music", ".mp3")
