Python - create multiple subfolders

In this article, we would like to show you how to create multiple subfolders in Python.

Quick solution:

import os

N = 10

for i in range(N):
    os.makedirs(os.path.join("C:\\some_path\example_directory", "subfolder" + str(i)), exist_ok=True)

Note:

The exist_ok parameter was added in Python 3.5. Set it on True so you won't get FileExistsError if the directory exists.

Practical example

In this example, we create a directory with multiple (N) subfolders in our project directory using makedirs() method from os module.

import os

N = 5

for i in range(N):
    os.makedirs(os.path.join("example_directory", "subfolder" + str(i)), exist_ok=True)

if you want to create multiple subfolders outside the project folder, you need to specify the full path:

import os

N = 5

for i in range(N):
    os.makedirs(os.path.join("C:\\some_path\example_directory", "subfolder" + str(i)), exist_ok=True)

result:
