参数化装饰器

def repeat(times):
   def decorator(func):
       def wrapper(*args, **kwargs):
           for _ in range(times):
               result = func(*args, **kwargs)
           return result
       return wrapper
   return decorator

@repeat(3)
def greet(name):
   print(f"Hello {name}")

类装饰器

class CountCalls:
   def __init__(self, func):
       self.func = func
       self.count = 0
   
   def __call__(self, *args, **kwargs):
       self.count += 1
       print(f"调用次数: {self.count}")
       return self.func(*args, **kwargs)
