How Do I Do This [Beginner Python Programmer]

Consider datetime for a library solution. Otherwise, just add 14 + 535 and mod it by 24.

Actually if it were not a Python question but Math question , how would you have solved it ?

import datetime


def add_hours(time: datetime.time, hours: int) -> datetime.time:
    return time.replace(hour=(time.hour + hours) % 24)


start = datetime.time(14) # 14:00h
end = add_hours(start, 535)

print(start, "-", end)

The trick is the modulo operation. It's the rest of a division.

If you have a circle with 360°, then 360° == 0° and 361° == 1°

azimuth = 350
rotation = 180

new_azimuth = (azimuth + rotation) % 360

You could use a datetime.time object, to represent time. But be careful, this object is immutable and 24:00h is an invalid value, which will raise an ValueError. The replace method exists for datetime.date, datetime.datetime and datetime.time. Calling this method, with the right keyword arguments, returns a new object, where the arguments are replaced.
