Countdown from 2 minutes - how?

[henrik]

Hi.

Can anyone tell me the python code for a simple countdown from eg. 2.00
minutes.

It should be printet out to the screen.
When it is finished it should write "Time is up"

Hope you can help.

here's a first version:

import time
time.sleep(2*60)
print "Time is up"

to improve this, I suggest reading the chapter on loops in the tutorial:

You need the module ``time`` :

import time
start = time.time()
lastprinted = 0
finish = start + 120
while time.time() < finish:
now = int(time.time())
if now != lastprinted:
print int(finish - now)
lastprinted = now
time.sleep(0.5) # this stops the system hanging whilst this is
running

print "Time is up"
