python，装饰器带参数，原理

 1 import time
 2 
 3 # 函数装饰器传参
 4 def zhuang1(hao):
 5     def zhuang2(func1):
 6         def funczhuang(*args, **kw):
 7             print(time.time())
 8             print(hao)
 9             print("第三层")
10             return func1(*args, *kw)
11 
12         print("第二层+可套代码")
13         return funczhuang
14 
15     print('第一层+可套代码')
16     return zhuang2
17 # 不用装饰器实现
18 def test():
19     time.sleep(1)
20     pass
21 
22 test1= zhuang1("J")
23 test = test1(test)
24 test()
25 
26 print("*"*100)
27 @zhuang1("Z")
28 def test1():
29     time.sleep(1)
30     pass
31 
32 
33 test1()

注：带参数装饰器，在原有闭包的前提下，再加一层
