The os.makedirs() method makes directories recursively. It creates all the intermediate directories needed to create the given directory.

Syntax of os.makedirs():

os.makedirs(path, mode=0o777, exist_ok=False)

Parameters

path This is the directory’s path to be created.
mode This is the directory mode to be created. The default value is 0o777 (octal).
exist_ok If set to True, it will not raise an error if the directory to be created already exists. The default value is False.

Return

This method does not return any value.

Example Codes: Use the os.makedirs() Method to Create a Directory

This example creates a directory named test in the current directory.

import os

os.makedirs('test')

Example Codes: Use the os.makedirs() Method to Create a Directory With Parents

This example creates a directory named test in the current directory with its parents.

import os

os.makedirs('test/sub1/sub2')

Example Codes: Use the os.makedirs() Method to Set the Mode of the Directory

This example creates a directory named test in the current directory with the mode 0o755.

import os

os.makedirs('test', mode=0o755)

Example Codes: Possible Errors While Using the os.makedirs() Method

Error Description
OSError This is raised when the given path is invalid.
FileExistsError This is raised when the directory to be created already exists, and exist_ok is set to False.

OSError

In this example, an invalid path is given, which results in an OSError.

import os

os.makedirs('/test/sub1/sub2')

Output:

Traceback (most recent call last):
  File "test.py", line 5, in <module>
    os.makedirs('/test/sub1/sub2')
  FileNotFoundError: [Errno 2] No such file or directory: '/test/sub1/sub2'

FileExistsError

In this example, the directory to be created already exists. Also, exist_ok is set to False, which results in a FileExistsError.

import os

os.makedirs('test', exist_ok=False)

Output:

Traceback (most recent call last):
  File "test.py", line 5, in <module>
    os.makedirs('test', exist_ok=False)
  FileExistsError: [Errno 17] File exists: 'test'
