在python中创建计时器

Question

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，当分钟数达到20分钟时，会弹出一个对话框，该对话框不是问题。但是我的分钟变量在此代码中没有增加。

您可以使用time.sleep以下方法真正简化整个程序：

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
