Creating a timer in python

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 

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.

See Timer Objects from threading.

How about

from threading import Timer  def timeout():     print("Game over")  # duration is in seconds t = Timer(20 * 60, timeout) t.start()  # wait for time completion t.join() 

Should you want pass arguments to the timeout function, you can give them in the timer constructor:

def timeout(foo, bar=None):     print('The arguments were: foo: {}, bar: {}'.format(foo, bar))  t = Timer(20 * 60, timeout, args=['something'], kwargs={'bar': 'else'}) 

Or you can use functools.partial to create a bound function, or you can pass in an instance-bound method.
