Python timer countdown

Question

I want to know about timer in Python.

Suppose i have a code snippet something like:

def abc()
   print \'Hi\'  
   print \'Hello\'
   print \'Hai\'
<         


        

Answer 1

time.sleep is fine in this case but what if the abc() function takes half a second to execute? Or 5 minutes? In this case you should use a Timer object.

from threading import Timer

def abc():
    print 'Hi'  
    print 'Hello'
    print 'Hai'

for i in xrange(3):
    Timer(i, abc).start()
