时间循环python -清零世界

概述

我正在尝试在while循环中计时while循环,执行所需的总时间,并记录每次循环所需的时间.如果可能的话,我需要一种方法来使用我的代码实现这一点,或者开放我可能还不知道的不同概念.@H_404_2@

@H_404_2@

import random
import time
import sys

def main():


    loopercpu = 500
    start = time.time()
    while (loopercpu != 0):
        #start = time.time()

        #this is the computation for 3 secs
        time.sleep(3)
        random_number = random.randint(0,1000)

        #Send to printer for processing
        #.75 secs to 4.75 secs to generate a pause before printing
        secondsPause = random.uniform(.75,4.75)


        #This is the printer function
        printerLooper = True
        while printerLooper == True :
            print("Sleeping for ",secondsPause," seconds")
            print(random_number)
            printerLooper = False


        #
        print("total time taken this loop: ",time.time() - start)
        loopercpu -= 1    



main()

循环将打印一个时间,但我非常确定它没有考虑嵌套的while循环休眠时间.我怎样才能允许python同时循环,循环,它需要做的每个循环(在这种情况下是500)？

@H_404_2@

program_starts = time.time()
while(True):
    Now = time.time()
    print("It has been {0} seconds since the loop started".format(Now - program_starts))

这是因为启动在整个执行时间内保持静态,而您的结束时间随着时间的推移而稳步增加.
通过在循环中放置开始时间,您可以确保在程序运行时您的开始时间也在增加.@H_404_2@

@H_404_2@

while (loopercpu != 0):
    start_time = time.time()
    # Do some stuff
    while printerLooper == True :
        print("Sleeping for "," seconds")
        print(random_number)
        printerLooper = False
    end_time = time.time()

    print("total time taken this loop: ",end_time - start_time)
