如何在一个项目中获得最终的总计？

Question

此程序将要求用户提供其拥有的半美元、25美分、10美分、5美分和1美分的数量，然后计算总价值。变化的总价值以美分的总数显示，然后以美元和美分的单独数字显示。我想包括用户完成后显示的最终总数；它将显示整个会话中输入的所有金额的总和（即所有循环迭代）。那么我该如何编写代码呢

#getCoin function
def getCoin(coinType):
    c = -1
    while c < 0:
        try:
            c = int(input("How many " + coinType + " do you have? "))
            if c < 0:
                print("Coin counts cannot be negative. Please re-enter.")
        except  ValueError:
            print("llegal input. Must be non-negative integer. Re-enter.")
            c = -1
            
    return c

print("Welcome to the Change Calculator")
print()

choice = input ("Do you have any change (y/n)?")
while choice.lower() == "y":
    h = getCoin("Half-Dollars")
    q = getCoin("Quarters")       
    d = getCoin("Dimes")
    n = getCoin("Nickel")
    p = getCoin("Pennies")
    print()

    TotalVal = (h*50) + (q*25) + (d*10) + (n*5) + p
    print("You have " + str(TotalVal) + " cents.")

    dollars = TotalVal // 100   # // is for division but only returns whole num
    cents = TotalVal % 100      # % is for modulos and returns remainder of whole number

    print("Which is " + str(dollars) + " dollars and " + str(cents) + " cents.")

    choice = input("Do you have more change (y/n)? ")

print("Thanks for using the change calculator.")

finalTotal = TotalVal
print("You had a total of" + finalTotal + " cents.")
print("Which is" + str(finalTotalDollars) + " dollars and" + str(finalTotalCents) + " cents.")

为了在用户想要再次播放时实现这一点，您可以使用“打开”、“读取”和“写入”来存储用户信息，使用外部文件进行写入和读取

您可以使用notepad as.txt并写入用户名、货币和重复，因此登录时会在名称后的行中检查并调用货币
