Build a Time Calculator Project - Build a Time Calculator Project

Python

Tell us what’s happening:

I’m attempting to complete the project to build a time calculator. I’ve written my code using Spyder (python) and it fully works. It returns all the correct values for each test when I call the function and manually enter the required parameters. However, when I copy and paste my code into the freecodecamp IDE and run the tests, they all fail. I’m not sure why, it returns exactly what it asks for, the exact same punctuation, the exact same values. Any help would be much appreciated!

Your code so far

def add_time(start, duration, day=True):

    starting_hours = int(start[:start.find(':')])
    starting_minutes = int(start[start.find(':') + 1:start.find(' ')])
    meridiem = start[start.find(' ') + 1:]
    duration_hours = int(duration[:duration.find(':')])
    duration_minutes = int(duration[duration.find(':') + 1:])

    total_minutes = starting_minutes + duration_minutes
    minutes = total_minutes % 60

    total_hours, number_of_days, meridiem = add_hours(starting_hours, duration_hours, total_minutes, meridiem)

    if total_hours == 0:
        total_hours = 12

    if day != True:
        weekday = day_of_week(day, number_of_days)
        if number_of_days == 0:
            if minutes < 10:
                print(f'{total_hours}:0{minutes} {meridiem}, {weekday}')
            else:
                print(f'{total_hours}:{minutes} {meridiem}, {weekday}')
        if number_of_days == 1:
            if minutes < 10:
                print(f'{total_hours}:0{minutes} {meridiem}, {weekday} (next day)')
            else:
                print(f'{total_hours}:{minutes} {meridiem}, {weekday} (next day)')

Hi and welcome to the forum :wave:

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

5:42 PM
None

Your function needs to return the string, not print it.

The function should add the duration time to the start time and return the result.

So I have just have to replace all the print statements with return statements?

Yes, you will need to do that.
