python 装饰器写在类中

from functools import wraps

class A: # Decorator as an instance method def decorator1(self, func): @wraps(func) def wrapper(*args, *kwargs): print('Decorator 1') return func(args, **kwargs) return wrapper

# Decorator as a class method
@classmethod
def decorator2(cls, func):
    @wraps(func)
    def wrapper(*args, **kwargs):
        print('Decorator 2')
        return func(*args, **kwargs)
    return wrapper

用法

As an instance method

a = A() @a.decorator1 def spam(): pass

As a class method

@A.decorator2 def grok(): pass
