def my_function(x, y): time.sleep(1) return x + y my_function(10,20) 单个函数上使用多个装饰器的方法: @log_execution @timing_decorator def my_function(x, y): time.sleep(1) return x + y my_function(10,20) 5. 通知装饰器(Notification decorator) 在生产系统中非常有用的一个装饰器是...
loop = timing(loop) print("执行loop...") loop(2) # 输出2.022785186767578 可能略有差异 print("结束loop") 1. 2. 3. 4. Python对于上面这种修饰提供了语法糖,通过在函数名上面使用@decorate_name即可,如下: @timing def loop(sze): for i in range(sze): time.sleep(1) print("执行loop...") ...
@timing_decorator def slow_function(seconds): time.sleep(seconds) return f"Slept for {seconds} seconds" # 使用装饰器 print(slow_function(2)) 在这个例子中,timing_decorator装饰器记录了slow_function的执行时间,并在执行后打印出来。装饰器通过接收slow_function函数,并返回一个新的函数wrapper,实现了功能...
So, what I'm trying to accomplish is timing how long a function takes to execute. I have functions.py and main.py in following fashion: #functions.py def function(list): does something return list ... #main.py import functions ...stuff... while: list = gets list from file functions...
本文实例讲述了python定时执行指定函数的方法.分享给大家供大家参考.具体实现方法如下: # time a function using time.time() and the a @ function decorator # tested with Python24 vegaseat 21aug2005 import time def print_timing(func): def wrapper(*arg): t1 = time.time() res = func(*arg) t2...
