How can I use decorators to log exceptions in Python?

You can create a decorator that wraps your function and logs any exceptions that occur during its execution.

Can you show me an example of such a decorator?

Sure! Here's a simple example:

import logging

def log_exceptions(func):
    def wrapper(*args, **kwargs):
        try:
            return func(*args, **kwargs)
        except Exception as e:
            logging.error(f'Exception occurred in {func.__name__}: {e}')
            raise
    return wrapper

How do I use this decorator on a function?

You can apply the decorator by using the @log_exceptions syntax above your function definition. For example:

@log_exceptions
def divide(a, b):
    return a / b

What happens if an exception occurs in the decorated function?

If an exception occurs, it will be logged, and the exception will be re-raised, allowing you to handle it further if needed.
