# How to rename multiple files recursively using Python?

PythonServer Side ProgrammingProgramming

You can use os.walk to recursively walk through the directory and subsequently use os.rename to rename the files.

## Example

import os
def replace(folder_path, old, new):
for path, subdirs, files in os.walk(folder_path):
for name in files:
if(old.lower() in name.lower()):
file_path = os.path.join(path,name)
new_name = os.path.join(path,name.lower().replace(old,new))
os.rename(file_path, new_name)

You can use this function as follows −

replace('my_folder', 'IMG', 'Image')

This will find all files recursively within the folder and its sub-folders and replace IMG with Image in each one of them. You can modify the function as it suits you for a better result suited to your need.
