How to Rename Multiple Files in a Directory Using Python

Renaming Multiple Files in a Directory Using Python

Renaming multiple files in a directory can be a tedious task if done manually. Python, however, provides several options for automating this process, making it more efficient and accurate.

Approach:

Using os.path.split

import os
folder = 'dir'
files = os.listdir(folder)

for file in files:
    # Split the filename and extension
    filename, ext = os.path.splitext(file)

    # Modify the filename
    modified_filename = filename.split('_')[1]

    # Combine the modified filename with the extension
    new_file = modified_filename + ext

    # Rename the file
    os.rename(os.path.join(folder, file), os.path.join(folder, new_file))

Using String Manipulation:

import os
folder = 'dir'
files = os.listdir(folder)

for file in files:
    if file.startswith('CHEESE_'):
        # Remove 'CHEESE_' from the filename
        new_file = file[7:]

        # Rename the file
        os.rename(os.path.join(folder, file), os.path.join(folder, new_file))

Using os.rename

import os
folder = 'dir'
files = os.listdir(folder)

for file in files:
    if file.startswith('CHEESE_'):
        # Get the new filename
        new_file = file[7:]

        # Use os.rename() to change the filename
        os.rename(os.path.join(folder, file), os.path.join(folder, new_file))

All of these approaches accomplish the desired outcome of renaming files in a directory, removing the "CHEESE_" prefix and retaining the original extension.
