python 3.x函数装饰器

函数对象在被调用时，函数装饰器将会起作用：
 

from time import ctime,sleep

def tsfunc(func):
    def wrappedFunc():
        print('[%s] %s() called'% (ctime(),func.__name__))
        return func()
    return wrappedFunc

@tsfunc
def foo():
    pass

foo()
sleep(4)

for i in range(2):
    sleep(1)
    foo()

运行结果：

[Thu Feb 27 11:14:04 2020] foo() called
[Thu Feb 27 11:14:09 2020] foo() called
[Thu Feb 27 11:14:10 2020] foo() called
