comparing times with datetime

I'm new to python, and I'm trying to use a time in a while statement.

while hours_left is greater than 0:00
{
    do some stuff
    decrement hours_left
}

is what I'm trying to achieve.

however I can't just say hours_left > 0 because it's an int.

any ideas how I can type 0:00 as datetime?

Thanks!

You want a timedelta object.

import datetime
current_time = datetime.datetime(2011,12,12,12,0,0) # High Noon!
end_time = datetime.datetime(2011,12,25,0,0,0)      # Santa?
while end_time-current_time > datetime.timedelta(0):
    do_stuff()
    current_time = current_time - datetime.timedelta(hours=1)

Sure, take a current datetime object, add the hours left to it, and then compare the current object to the new one with the hours left. If the current one is less than the new one then you still have hours left.
