Tell us what’s happening:

I am getting an output but it is in decimal places and not in a standard time format

Your code so far

def add_time(start, duration, weekday = False):
    weekday_index = {'Monday': 0, 'Tuesday': 1, 'Wednesday': 2, 'Thursday': 3, 'Friday': 4, 'Saturday': 5, 'Sunday': 6}
    weekday_array = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
    duration_tuple = duration.partition(':')
    duration_minutes = int(duration_tuple[2])
    duration_hours = int(duration_tuple[0])

    start_tuple = start.partition(':')
    start_minutes_tuple = start_tuple[2].partition(' ')
    start_hours = int(start_tuple[0])
    start_minutes = int(start_tuple[0])
    am_pm = start_minutes_tuple[2]
    am_pm_switch = {'AM': 'PM', 'PM': 'AM'}

    days_amount = int(duration_hours) / 24

    end_minutes = start_minutes + duration_minutes
    if end_minutes >= 60:
        start_hours += 1
        end_minutes = end_minutes % 60
    amount_of_am_pm_switches = int((start_hours + duration_hours) / 12)
    end_hours = start_hours + duration_hours

    end_minutes = end_minutes if end_minutes > 9 else '0' + str(end_minutes)
    end_hours = end_hours = 12 if end_hours % 12 == 0 else end_hours % 12
    if am_pm == 'PM' and start_hours + (duration_hours % 12) >= 12:
        days_amount += 1

    am_pm = am_pm_switch[am_pm] if amount_of_am_pm_switches % 2 == 1 else am_pm

    print(amount_of_am_pm_switches)
    print(days_amount)

    return_time = str(end_hours) + ':' + str(end_minutes) + ' ' + am_pm
    if weekday:
        weekday = weekday.lower()
        weekday = weekday[0].upper() + weekday[1:]
        index = int((weekday_index[weekday]) + days_amount) % 7
        new_day = weekday_array[index]
        return_time += ', ' + new_day

        if days_amount == 1:
            return return_time + ' ' + '(next day)'
        elif days_amount < 2 and amount_of_am_pm_switches > 1:
            return return_time +' ' + '(next day)'
        elif days_amount >= 2:
            return return_time +' (' + str(int(days_amount)) + 'days later'

add_time('3:30 PM', '2:12')

To check what function actually returns, wrap it with the print, ie.:

print(add_time('3:30 PM', '2:12'))
3

thanks for the suggestion, however, it doesn’t change the return of the function

4

it doesn’t change the return, but it allows you to check what it returns

to make it even more clear we can write print("output", add_time('3:30 PM', '2:12')). And now seeing the terminal there is output None: your function returns None
