Python folder names in the directory

Question

how can i get the folder names existing in a directory using Python ?

I want to save all the subfolders into a list to work with the names after that but i dont know

Answer 1

Python 3.x: If you want only the directories in a given directory, try:

import os
search_path = '.'   # set your path here.
root, dirs, files = next(os.walk(search_path), ([],[],[]))
print(dirs)

The above example will print out a list of the directories in the current directory like this:

['dir1', 'dir2', 'dir3']

The output contains only the sub-directory names.
If the directory does not have sub-directories, it will print:

[]

os.walk() is a generator method, so use next() to only call it once. The 3-tuple of empty strings is for the error condition when the directory does not contain any sub-directories because the os.walk() generator returns 3-tuples for each layer in the directory tree. Without those, if the directory is empty, next() will raise a StopIteration exception.

For a more compact version:

dirs = next(os.walk(search_path), ([],[],[]))[1]
