试图写入CSV文件，但收到错误消息：“\u CSV.writer”对象不可编辑

Question

我正在尝试使用Python创建一个票务系统，该系统能够写入和读取文件，但该程序似乎什么都不写。我收到了错误消息：

'_csv.writer' object is not iterable

“OKU”是指禁用的BTW.
“IC号码”是马来西亚的身份证号码

预期产出：

Name    Age  Sex    Malaysian   OKU  IC-Number  Passport-Number  Fee
Jack    25   Male   0           0      -        12345678         23.70

我已附上以下代码：
