python - 在 csv 文件 python 中添加行 - "wb"不起作用

Question

代码可以工作，除了在 csv 文件中，运行此代码后，每个值之间现在有一个空行 - 当我用 google 搜索这个问题时，它建议使用“wb”，但这会返回错误

TypeError: 'str' does not support the buffer interface

键盘代码为 2580，CSV 格式为

bakerg,ict,George Baker,11HM,NORMAL

upgradetoadmin()

Answer 1

尝试

 open('Student Data.csv', 'wb', newline='')

因为官方documentation要求我们这样做
