定义存款回路

Question

当我运行代码时，存款回路给我一个错误，说我没有定义存款。这与阅读和写入文件有什么关系？我的代码似乎是对的，所以有人可以帮忙吗？任何帮助将不胜感激。谢谢。

Answer 1

您检查是否有余额或存款，但你检查什么存款的选择是（储蓄或检查），而不管用户是否实际选择“存款”。缩进相关的块，这样，只有当用户选择“存款”出现：

elif (command=="d"):  
    deposit=input("Press 1 for savings account//Press 2 for chequing account") 
    if deposit=='1': 
     ... 
    elif deposit=='2': 
     ... 

Answer 2

您使用的保证金，作为一个整数，但被引用之前，你从来没有定义的对象（在开始）

deposit = 0
