What are advanced decorator patterns in Python?

Advanced decorator patterns in Python allow you to modify the behavior of functions or methods dynamically. They can be used for logging, access control, memoization, and more.

Can you give me an example of a decorator that logs function calls?

Sure! Here's a simple logging decorator:

import functools

def log_function_call(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        print(f'Calling {func.__name__} with {args} and {kwargs}')
        return func(*args, **kwargs)
    return wrapper

How can I use multiple decorators on a single function?

You can stack decorators by applying them one after the other above the function definition. For example:

@decorator_one
@decorator_two
def my_function():
    pass

What are some common use cases for decorators?

Common use cases include logging, enforcing access control, caching results, and measuring execution time.
