修饰器练习

import time
# def foo():
#     print("in the foo")
#     bar()
# #foo()
# def bar():
#     print("in the bar")
#
# foo()
# bar()
def bar():   #基本函数
    time.sleep(4)
    print("in the bar")
def test1(func1):   #装饰器--用来装饰基本函数，为其增加了计时器的功能
    start_time = time.time()
    func1()  #func1 = bar -- print("in the bar")
    stop_time = time.time()
    print("func1 is running %s" %(stop_time - start_time))

def test2(func2):
    print(func2)
    return func2

print(test2(bar)) #bar 传的是bar对应的内存地址
test2(bar())  #bar()传的是bar()函数的内容
