Python, how to create a directory

To create a directory, use the os.mkdir() method provided by the os standard library module:

import os

dirname = '/Users/flavio/test'

os.mkdir(dirname)

Creating a folder can raise an OSError exception, for example if the disk is full or the directory already exists, so we use a try block to catch it and gracefully handle the problem by printing an error message:

import os

dirname = '/Users/flavio/test'

try:
    os.mkdir(dirname)
except OSError:
    print('Failed creating the directory')
else:
    print('Directory created')
