Python os.path subfolder discover

Question

I'm looking for effective way to go to every folder (including subfolder) in my directory list. I then need to run some processes on that folder (like size, number of folders and files etc.).

I know that I have 2 options for that: - Recurrence (my current implementation, code below) - At start of program generating list of all folders and invoking my function in look

I know that my current implementation is not perfect can somebody take a look on it and possibly advise any updates. In addition can somebody help me howto (I'm assuming using os.path library) generate list of all folder including subfolders ?

My current code that analyse folder (using recurrence):

def analyse_folder(path, resultlist=[]):
 # This is trick to check are we in last directory
 subfolders = fsprocess.get_subdirs(path)
 for subfolder in subfolders:
 analyse_folder(subfolder, resultlist)
 files, dirs = fsprocess.get_numbers(subfolder)
 size = fsprocess.get_folder_size(subfolder)
 resultlist = add_result([subfolder, size, files, dirs], resultlist)
 return resultlist

This is the code that getting list of subfolders inside folder:

def get_subdirs(rootpath, ignorelist=[]):
 # We are starting with empty list
 subdirs = []
 # Generate main list
 for path in os.listdir(rootpath):
 # We are only interested in dirs and thins not from ignore list
 if not os.path.isfile(os.path.join(rootpath, path)) and path not in ignorelist:
 subdirs.append(os.path.join(rootpath, path))
 # We are giving back list of subdirectories
 return subdirs

And this is simple function to add it to resullist:

def add_result(result, main_list):
 main_list.append(result)
 return main_list

So if anyone can: 1) Tell me is my attitude is good 2) Provide me code to generate list of all of directories in given folder (for example everything under C:\users)

Thank you

Try os.walk:

import os
for (root, dirs, files) in os.walk(somefolder):
 # root is the place you're listing
 # dirs is a list of directories directly under root
 # files is a list of files directly under root

• FiR3WaLL: Hello, thank you - this is list of directories directly above root - I want to get directories above this subdirs , and above and above - if you now what I mean (everyt folder path that is under root)
• Freek Wiekmeijer: When you do an iteration for (root, dirs, files) in os.walk("/home/someuser"), it will start listing /home/someuser and recurse all the way until there are no deeper levels.
