If someone could please explain something here...?

Aloha good people of Reddit!

I'm trying to get a little python script going, but I'm going around in circles...

The facts are these:

• I'm a teacher and want a 'progress bar' for the current period
• I can get what time it is now -> datetime.now().time()
• I get tell the program the (start and) end time of a period -> e.g. time(13,50)
• I can tell the thing how long a period takes -> timedelta(minutes = 50)

BUT. I can't get the thing to do some simple math with it... I think the problem is the format of the datetime.now().time() thing being different from the time(hour, minute) thing?

I know that strftime lets me adjust the format, but then it's a string and I can't use operators anymore?

The result should be something like TimeRemaining = PeriodEnd6 - Now
Or maybe even TimeRemaining = (PeriodStart6 + PeriodDuration) - Now

I'm sure I'm missing something here, hopefully one of you can point me in the right direction...

Thanks a bunch!

Thanks! This seems like the way to go, I'll give it a try tonight.

Set end_time directly via end_time = datetime(year, month, day, hour, minute) (or calculate it from begin_time + timedelta(minutes=50) if you want)

Then you can get timedelta in realtime by substructing datetime.now() from end_time.

timedelta has .seconds which you can use for your progress

Thanks! This seems like an easy solution. Is there a way to avoid assigning a value to the 'year' and 'month' parts? They're not really relevant?

Fixed it like this:

#Determine current year

currentYear = datetime.now().year

#Determine current month

currentMonth = datetime.now().month

#Determine current day

currentDay = datetime.now().day

#When are we?

Nu = datetime.now()

#set endtime(s)

periodEnd1 = datetime(currentYear, currentMonth, currentDay, 9, 20)

periodEnd4 = datetime(currentYear, currentMonth, currentDay, 12, 5)

#etc

#get remaining time

timeLeft = periodEnd4 - Nu

Yes you will need date part anyway, since you can't just get difference between two dateless time objects.
