当我运行代码时，存款循环给我一个错误，说我没有定义存款。这与读取和写入文件有什么关系吗？我的代码似乎没错，有人可以帮忙吗？任何帮助将不胜感激。感谢。

您检查余额或存款，但随后检查存款选择（节省或检查），无论用户是否实际选择了＃34;存款。＆＃34;缩进相关的块，以便它们仅在用户选择＆＃34;存放＆＃34;：
时才会出现elif (command=="d"):
deposit=input("Press 1 for savings account//Press 2 for chequing account")
if deposit=='1':
...
elif deposit=='2':
...

您使用存款作为整数，但在引用之前（在项目开始时）您从未定义过该对象。
deposit = 0
