What are some practical use cases for decorators in Python 3.10?

Decorators in Python 3.10 can be used for logging, access control, memoization, and more. Would you like examples?

Yes, please provide an example of a logging decorator.

Sure! Here's a simple logging decorator:

import logging

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

This decorator logs the function name and its arguments whenever it's called.

That’s great! Can you show me how to use it?

Absolutely! You can use it like this:

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

result = add(5, 3)  # This will log the function call.

Now, whenever you call add, it will log the call details.

Thanks! What other use cases are there?

Other use cases include caching results with memoization, enforcing access control, and modifying input/output of functions.
