How to calculate the time and find the remaining hours

Question

Question How do I print out the remaining hours of overtime

Example: I have to be at work for 8 hours, and if my time goes over 8 hours as shown in OUTPUT then I just wanna have the 00:03:00 printed out.. Meaning that I have 3 min overtime that day.

from datetime import datetime

s1 = '07:15:00'
s2 = '16:18:00'
FMT = '%H:%M:%S'

tdelta = datetime.strptime(s2, FMT) - datetime.strptime(s1, FMT)

print(tdelta)

OUTPUT

9:03:00

Take another look at your code. You probably assigned `s3 = '08:00:00` to reduce the difference of your `tdelta` but you never referenced it back. How did you expect it to work? A hint: look into `datetime.timedelta`, it's used to add/subtract time difference. — r.ook, Oct 12 '18 at 13:10

You need to subtract the length of the working day (and it would appear an hour to account for breaks) from tdelta to determine the excess.

Subtract the length of the working day with a timedelta object...

from datetime import datetime, timedelta

s1 = '07:15:00'
s2 = '16:18:00'
FMT = '%H:%M:%S'

work_time = timedelta(hours=8)
lunch_time = timedelta(hours=1)

tdelta = datetime.strptime(s2, FMT) - datetime.strptime(s1, FMT) - work_time - lunch_time

print(tdelta)

Output:

0:03:00
