本文实例讲述了Python计算程序运行时间的方法。分享给大家供大家参考。具体实现方法如下：

复制代码 代码如下:

import time

def start_sleep():
time.sleep(3)

if name == 'main':

The start time

start = time.clock()

#A program which will run for 3 seconds  
start_sleep()

#The End time   
end = time.clock()

print("The function run time is : %.03f seconds" %(end-start))

# End
