定义存款循环

Question

当我运行代码时，deposit循环给我一个错误，说明我没有定义deposit。这和读写文件有什么关系吗？我的代码似乎是对的，有人能帮忙吗？任何帮助都将不胜感激。谢谢。在

Answer 1

您检查余额或存款，然后检查存款选择（储蓄或支票），而不管用户是否实际选择了“存款”。缩进相关块，使其仅在用户选择“存款”时出现：

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

Answer 2

您将deposit用作整数，但在引用对象之前（在项目开始时）从未定义过该对象

 deposit = 0
