函数作装饰器 ，类做装饰器
一.用类写装饰器
"""
用类写装饰器
func = Decorator(func)
func('abc',18)
"""
class Decorator(object):
def __init__(self, f):
self.f = f
def __call__(self,*args,**kwargs):
print("decorator start")
self.f(*args,**kwargs)
print("decorator end")
@Decorator
def func(name,age):
print("{0}\' is {1}".format(name,age))
print("func")
func('abc',18)
二.用函数写装饰器
'''
用函数写装饰器
func1 = Decorator1(func)
func1('abc',18)
'''
def Decorator1(f):
def wrapper(*args,**kwargs):
print("decorator start")
f(*args, **kwargs)
print("decorator end")
return wrapper
@Decorator1
def func1(name,age):
print("{0}\' is {1}".format(name, age))
func1('abc',18)
