硬币计数游戏制作变化

Question

我正在做一个Python编程课程，我一直试图围绕如何实现它。我写了一些代码，我试图修复任何弹出的错误，但我感到困惑，并没有解决任何问题，这就是为什么我要求你们。如果您看到我迄今为止所写的内容，我会很感激任何想法和建议。我特别想弄清楚如何做最后一部分，我必须得到高于或低于2美元的价值。

我在做这个练习：

创建一个改变计数的游戏，获取用户输入必要做完全两块钱的硬币数量。实现一个Python程序，提示用户输入5c硬币，10c硬币，20c硬币，50c硬币，1美元硬币和2美元硬币。如果所输入的这些硬币的总价值等于两美元，则该程序应该祝贺用户赢得该游戏。否则，程序应该显示一条消息，建议总数不完全是两美元，并显示该值高于或低于两美元。

更新：我对最后一个函数做了一些更改，它工作得很好。

#Global Variables 

v_five = float(0.05) 
v_ten = float(0.10) 
v_twenty = float(0.20) 
v_fifty = float(0.50) 
v_one_dollar = int(1) 
v_two_dollar = int(2) 
dollar = 0 

def main(): 

    """The main function defines the variables that are needed by taking input 
    from the user. The main() function is calling all the other functions one 
    by one to execute their intended commands and give the results""" 

    intro() #Displays the rules of the game 

    #Takes input from the user. One input per denomination

    """This function checks whether the total was over or under $2 and displays a 
    win or loose message for the user. Also shows the total that the user entered"""

     #is 2 or not 
     print(" \n Congratulations! You've hit a perfect 2!") 
     print("") 
    else: 
     if dollar < 2.00: 
      print(" \n Oops! You were a little under 2!") 
      print("") 
      print(" Your total was: ", dollar) 
     else: 
      if dollar > 2.00: 
       print(" \n Oh no! You went over 2!") 
       print("") 
       print(" Your total was: ",dollar) 

main() 

Answer 1

好，居然有是一对错误的：

功能calculate_value并返回一个值，但它不是在所有

return_dollar = calculate_value(five,ten,twenty,fifty,one_dollar,two_dollar) 

分配，你必须通过该值CalculateAndPrint。

CalculateAndPrint(return_dollar) 

你也改变CalculateAndPrint的定义：

def CalculateAndPrint(dollar): 

在PC上安装的Python 3.0，所以我不能测试所有程序我没有，但是这是两个问题，我可以现在看。

Answer 2

就像一个风格问题，你为什么不把所有的硬币列表：

coin_list = [five, ten, twenty, fifty, one_dollar, two_dollar] 
show_change(coin_list) 
calculate_value(coin_list) 
CalculateAndPrint(coin_list) 

注意：您需要更改上述功能的def的。
