Renaming a File in Python: A Comprehensive Guide

Introduction

Renaming files is a common task in programming, whether it's for organizational purposes or simply to make files easier to identify. Python provides several methods for performing this operation, including the os.rename() function.

Using os.rename()

The os.rename() function is the most straightforward way to rename a file in Python. It takes two arguments: the old file name and the new file name. For example, to rename a.txt to b.kml, you would use the following code:

import os

os.rename('a.txt', 'b.kml')

Usage:

The syntax for os.rename() is as follows:

os.rename(old_name, new_name)

where:

• old_name: The current file name, including the file extension.
• new_name: The new file name, including the file extension.

Example:

To rename "from.extension.whatever" to "to.another.extension," you would use the following code:

os.rename('from.extension.whatever','to.another.extension')
