Question

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)
