From CS50P Problem Set 1, Meal Time:

“Structure your program per the below, wherein convert is a function (that can be called by main) that converts time, a str in 24-hour format, to the corresponding number of hours as a float. For instance, given a time like “7:30″ (i.e., 7 hours and 30 minutes), convert should return 7.5 (i.e., 7.5 hours)”

This is my code:

time = input("What time is it? ")
hr, mn = time.split(":")

hr = int(hr)
mn = int(mn)


def main(hr, mn):

    if hr == (7) and mn in range(00, 59):
        print("Breakfast Time")
    elif hr == (8) and mn == (00):
        print("Breakfast Time")
    elif hr == (12) and mn in range(00, 59):
        print("Lunch Time")
    elif hr == (13) and mn == (00):
        print("Lunch Time")
    elif hr == (18) and mn in range(00, 59):
        print("Dinner Time")
    elif hr == (19) and mn == (00):
        print("Dinner Time")
    else:
        print()

    convert(hr, mn)

def convert(hr, mn):
    hr = int(hr)
    mn = int(mn)/60
    time = hr + mn
    print(float(time))


if __name__ == "__main__":
    main(hr, mn)

This is what check50 tells me:
Convert successfully returns decimal hours
Did not find “7.5” in “Input: “
