在csv文件python中添加了行-“；wb"；不起作用

除了csv文件中的代码外，运行此代码后，每个值之间现在都有一个空行-当我搜索此问题时，它建议使用“wb”，但返回错误

TypeError: 'str' does not support the buffer interface

键盘的代码为2580，CSV的格式为

bakerg,ict,George Baker,11HM,NORMAL

代码

试一试

因为官员要求我们这样做

不确定它是否有效，但请尝试打开（'Student Data.csv'，'w'，newline=''）并用结果回答IO.UnsupportedOperation:不可读不可读？你在哪儿看书？（尝试使用

wb

或

a+

）谢谢，wb和换行符=''修复了它
