CS50P problem set 1 Meal Time unknown error

Question

I made a solution for problemset 1, Meal Time from CS50P and I can't get a check from check50. The code works for me if I input the code myself but when I run check50 I get the error: I found the correct code here: Meal Time issues

But I can't find the problem in my code when I compare it with the code of the commentator.

My code:

def main():
    n = input("What time is it? ").split(":")
    answer = convert(n)
    if 7 <= answer <= 8:
        print("breakfast time")
    elif 12 <= answer <= 13:
        print("lunch time")
    elif 18 <= answer <= 19:
        print("dinner time")
    else:
        print("")
def convert(time):
    time = float(time[0]) + (float((time[1])) / 60)
    return time
if __name__ == "__main__":
    main()

Answer 1

The spec says:

convert is a function (that can be called by main) that converts time, a str in 24-hour format...

In this program, convert takes a list.
