How to Clean All .pyc Files in Python?

Estimated read time 2 min read

When Python interprets a .py file, it creates a corresponding bytecode file with a .pyc extension to speed up subsequent runs of the same code. However, sometimes these .pyc files can become outdated or corrupted, and it’s necessary to delete them to ensure your Python code runs smoothly. Here’s how to clean all .pyc files in Python:

import os

# Define the directory to search for .pyc files
directory = '/path/to/directory/'

# Recursively find all .pyc files in the directory
for root, dirs, files in os.walk(directory):
    for file in files:
        if file.endswith('.pyc'):
            # Delete the .pyc file
            os.remove(os.path.join(root, file))

This code uses the os module to recursively search for all .pyc files in the specified directory and its subdirectories. For each .pyc file found, it uses the os.remove() function to delete it. Note that this will permanently delete the files, so make sure you have a backup or are certain that you don’t need the files before running this code.

It’s also worth noting that modern versions of Python (3.2 and higher) automatically clean up .pyc files that are no longer needed, so manually deleting .pyc files may not always be necessary. However, it can still be a useful step in some cases, such as when you’re troubleshooting issues with your Python code.
