在python中创建一个计时器 [英] Creating a timer in python

问题描述

import time
def timer():
   now = time.localtime(time.time())
   return now[5]


run = raw_input("Start? > ")
while run == "start":
   minutes = 0
   current_sec = timer()
   #print current_sec
   if current_sec == 59:
      mins = minutes + 1
      print ">>>>>>>>>>>>>>>>>>>>>", mins

我想创建一种秒表，当分钟达到 20 分钟时，会弹出一个对话框，对话框不是问题.但是我的分钟变量在这段代码中没有增加.

I want to create a kind of stopwatch that when minutes reach 20 minutes, brings up a dialog box, The dialog box is not the problem. But my minutes variable does not increment in this code.

推荐答案

通过使用 time.sleep:

import time
run = raw_input("Start? > ")
mins = 0
# Only run if the user types in "start"
if run == "start":
    # Loop until we reach 20 minutes running
    while mins != 20:
        print(">>>>>>>>>>>>>>>>>>>>> {}".format(mins))
        # Sleep for a minute
        time.sleep(60)
        # Increment the minute total
        mins += 1
    # Bring up the dialog box here
