Python os module provides methods that help you perform file processing operations, such as renaming and deleting files.

To use this module you need to import it first and then you can call any related functions.

import os
# Rename a file from test1.txt to test2.txt

The remove() Method
You can use the remove() method to delete files by supplying the name of the file to be deleted as the argument.
