Python 巧用time模块计算函数的执行所需时间

#用装饰器demo演示
import time


def set_fun(func):
	def call_fun(*args, **kwargs):
		first_time = time.time()

		func_exec = func(*args, **kwargs)
		print(time.time() - first_time)
		return func_exec


	return call_fun


@set_fun
def test():
	print("test")
	time.sleep(1)


test()
