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'

And i want to print it every 1 second. Max three times;ie; 1st second i need to check the printf, 2nd second I need to check as well in 3rd second.

In my actual code variables value will be updated.
I need to capture at what second all the variables are getting updated.

Can anybody tell me how to do this.

Answer 1

Use time.sleep.

import time

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

for i in xrange(3):
    time.sleep(1)
    abc()
