How to Rename Multiple Files in a Directory with a Specific Filename Pattern Using Python?

Renaming Multiple Files in a Directory Using Python

In Python, renaming multiple files in a directory is a straightforward task. However, the query here suggests a more specific scenario where the filenames follow a particular pattern and need to be renamed accordingly.

To achieve this, we can utilize the os module's rename function. This function takes two arguments:

• src: The original filename
• dst: The new filename

In the provided example, we loop through the files in the current directory using os.listdir. For each file that starts with "cheese_", we remove the "cheese_" prefix from the filename and rename it accordingly.

Here's the updated code:

<code class="python">import os

for filename in os.listdir("."):
  if filename.startswith("cheese_"):
    os.rename(filename, filename[7:])</code>

This code successfully renames all files that start with "cheese_" by removing the prefix, resulting in filenames like "cheese_type.bar" and "cheese_type.foo."
