While循环等待输入python

问题描述

我对python中的while循环有疑问.我想制作一个在特定时间内执行while循环的程序.我想添加一个额外的功能，即在我们运行该程序时，可以通过按一个随机键来更改某个变量.

I have a question about while loops in python.I want to make a program that performs a while loop in a certain time.I want to add the extra feature that while the program us running,a certain variable can be changed by pressing a random key.

   from time import sleep
   import time
   i=0
   a=0
   while i<10:
       i=i+1
       i=i+a
       a=a+1
       time.sleep(1)
      print i

我想通过按任意键将变量a重置为0.如果不按任何按钮，循环应保持不变.我应该添加什么命令?

I want to do it that the variable a can be reset to 0 by pressing any key.The loop should continue unchanged if no button is pressed.What command should i add?

谢谢我试过:

import pygame
from pygame.locals import *
import time

i=0
a=0
pygame.init()
while i<10:
    pygame.event.get()
    i=i+a
    print i
    keys = pygame.key.get_pressed()
    if keys[K_ESCAPE]:
               i=0
    i=i+1
    time.sleep(1)
 pygame.quit()

但是现在当我按下按钮时什么也没发生.我想念什么?

But now nothing happens when I press a button.What did i miss?
