20小时前关门了。
每当我试图运行我的程序，它的工作，但没有也显示后。以下是代码和结果，我得到的。

def main():
    time = input("What time is it: ")
    converted_time = convert(time)
    print(converted_time)

def convert(time):
    hours,minutes = time.split(":")
    new_hours = float(hours)
    new_minutes = float(minutes)

    if new_hours >= 7 and new_hours <=8:
        print("Breakfast Time")
    elif new_hours >=12 and new_hours <=13:
        print("Lunch Time")
    elif new_hours >=18 and new_hours <=19:
        print("Dinner Time")
    else:
        print("")

if __name__ == "__main__":
    main()

What time is it? 7:00
answer: 
Breakfast Time
None

tried playing around with some of the print functions.
