Hi,
Why doesn’t my code pass?

def add_time(start, duration):

datas = {'h_s': int(start.split(':')[0]), 'm_s': int(start.split()[0].split(':')[1]), 'h_d': int(duration.split(':')[0]), 'm_d': int(duration.split(':')[1]), 'am_pm': start.split()[1]}

hour_start = datas['h_s']
hour_duration = datas['h_d']
min_start = datas['m_s']
min_duration = datas['m_d']
sign = datas['am_pm']
sign_list = []

if sign == 'AM':
    sign_list.append(sign)
    sign_list.append('PM')
else:
    sign_list.append(sign)
    sign_list.append('AM')

def calc_h(a, b):
    while b == 0:
        return a
    else:
        return calc_h(a + 1, b - 1)

a = calc_h(hour_start, hour_duration) // 12
hour_new = calc_h(hour_start, hour_duration) - (12 * a)
b = calc_h(min_start, min_duration) // 60
hour_new = hour_new + b
minutes_new = calc_h(min_start, min_duration) - (60 * b)

if a + b == 0:
    sign_new = sign_list[0]
elif (a + b) % 2 == 1:
    sign_new = sign_list[1]
elif a + b == 2:
    sign_new = sign_list[1]
else:
    sign_new = sign_list[0]

days = a // 2
if sign == "PM" and a > 0:
    days += 1

if days == 1:
    text = '(next day)'
elif days >= 2:
    text = f'({str(days)} days later)'
else:
    text = ''

if len(str(minutes_new)) < 2:
    new_time = print(f'{hour_new}:0{minutes_new} {sign_new} {text}')
else:
    new_time = print(f'{hour_new}:{minutes_new} {sign_new} {text}')

return new_time

add_time(‘3:30 PM’, ‘2:12’)

What your function returns?

My function respond 5:42 PM and all rest of examples are correct. Only what i don’t have yet is a day name changer.

I was tried but it didn’t work like before so i decided to make topic like you see. When I clicked “Submit” my window just disappeared and topic wasn’t created.

What do you mean respond? You can wrap the function call with the print() to see what is returned.

7

When i printed function I have: 5:42 PM
None

8

Then None is what function returns, and the 5:42 PM is what function prints on it own. add_time is expected to return the string with time.
