def main（）python中硬币的面额

Question

我正在写一个脚本，要求用户提供不同面额的硬币数量，然后显示美元和美分的总额。在

我在这一点上被卡住了，我很困惑到底是什么错了。这是我的入门课的一部分，所以需要修改的细节非常感谢。我需要的输出是告诉用户有多少美元和剩余的美分。我现在对输出有问题。这个函数告诉我正确的答案，但当用词来回答时，分币是关的。 例如，当一便士是5；五分镍币是3；一角硬币是3；四分之三时，总数是1.25，但是函数显示“你有1美元和1美分”

def main():
    pennies = get_input("Enter pennies  : ")
    nickels = get_input("Enter nickels  : ")
    dimes = get_input("Enter dimes    : ")
    quarters = get_input("Enter quarters : ")

    print("You entered : ")
    print("\tPennies   : " , pennies)
    print("\tNickels   : " , nickels)
    print("\tDimes     : " , dimes)
    print("\tQuarters  : " , quarters)

    total_value = get_total(pennies, nickels, dimes, quarters)
    dollars = get_dollars(pennies, nickels, dimes, quarters)
    left_over_cents = get_left_over_cents(pennies, nickels, dimes, quarters)

    print("Total = $",format(total_value, ".2f"), sep="")
    print("You have", dollars, "dollars and", left_over_cents, "cent(s)")

def get_input(message):
    get_input = int(input(message))
    while get_input <= 0:
        print("Error")
        get_input = int(input(message))
    return get_input

def get_total(pennies, nickels, dimes, quarters):
    pennies = (.01 * pennies);
    nickels = .05 * nickels;
    dimes = .10 * dimes;
    quarters = .25 * quarters;
    total_value = pennies + nickels + dimes + quarters
    return total_value

def get_dollars(pennies, nickels, dimes, quarters):
    total_value = get_total(pennies, nickels, dimes, quarters)
    dollars = format(total_value // 1, ".0f")
    return dollars

def get_left_over_cents(pennies, nickels, dimes, quarters):
    total_value = get_dollars(pennies, nickels, dimes, quarters)
    left_over_cents = total_value
    return left_over_cents

main()

错误实际上存在于您的get_input方法中。在

def get_input(message):
  get_input = int(input(message))
  while get_input <= 0:
    print("Error")
    get_input = int(input(message))
    return get_input

如果原始输入是>0，则返回None。您可能希望取消return子句一次。在
