How can I implement advanced logging with decorators in Python?

You can create a decorator that logs function calls, arguments, and return values. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import logging

logging.basicConfig(level=logging.INFO)

def log_decorator(func):
    def wrapper(*args, **kwargs):
        logging.info(f'Calling {func.__name__} with args: {args} and kwargs: {kwargs}')
        result = func(*args, **kwargs)
        logging.info(f'{func.__name__} returned: {result}')
        return result
    return wrapper

@log_decorator
def add(a, b):
    return a + b

add(2, 3)

What if I want to log to a file instead of the console?

You can configure the logging module to log to a file by specifying a filename in basicConfig. Here's how:

logging.basicConfig(filename='app.log', level=logging.INFO)
