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

Method decorators in Python can be used for logging, access control, memoization, and input validation.

Can you give me an example of a logging decorator?

Sure! Here's a simple logging decorator:

import time

def log_execution_time(func):
    def wrapper(*args, **kwargs):
        start_time = time.time()
        result = func(*args, **kwargs)
        end_time = time.time()
        print(f"{func.__name__} executed in {end_time - start_time} seconds")
        return result
    return wrapper

How would I use this logging decorator?

You can use it by applying the decorator to any function like this:

@log_execution_time
def my_function():
    # Your code here

What about using decorators for access control?

For access control, you can create a decorator that checks user permissions before allowing access to a function.
