What are some examples of decorator patterns in Python?

Can you explain what the decorator pattern is in Python?

The decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting other objects.

Can you give me some examples of how to implement decorators in Python?

Sure! A simple example is a logging decorator that logs function calls. Here's a basic implementation:

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

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

What are some built-in decorators in Python?

Some built-in decorators include @staticmethod, @classmethod, and @property. They modify methods in classes.

How do decorators work with classes?

Decorators can be applied to class methods and properties, allowing you to modify their behavior, similar to functions.
