How can I use contextlib for error handling in Python?

You can use the contextlib module to create context managers that handle exceptions gracefully. Would you like an example?

Yes, please provide an example of using contextlib for error handling.

Here's a simple example: you can create a context manager that suppresses specific exceptions using contextlib.suppress. For instance:

from contextlib import suppress

with suppress(FileNotFoundError):
    with open('file.txt') as f:
        data = f.read()

This will ignore the FileNotFoundError if 'file.txt' does not exist.

What if I want to log the error instead of suppressing it?

You can create a custom context manager that logs the error. Here's an example:

import logging
from contextlib import contextmanager

@contextmanager
def log_exceptions():
    try:
        yield
    except Exception as e:
        logging.error(f'An error occurred: {e}')

You can use this context manager to log any exceptions that occur within its block.
