Directories helps us make things more managable.  If there are a large number of files , then related files are placed in different directories. Hence, a directory can be said to be a collectopn of files and subdirectories. The module os in Python enables us to use various mathods to work with directories.

1. mkdir() method

The syntax is

os.mkdir("newdir")

import os
# Create a new directory test
os.mkdir("test")

 

2. chdir() method

getcwd() method displays the current directory in which we are working.
