pandas方法中的列列表

Question

我无法提供要在csv文件中返回的列列表。

trans.to_csv('study10.csv' , encoding='utf-8', columns = [("reg_no", "st_name", "c_six_to_ten", "values")] )

KeyError: "[[('reg_no', 'st_name', 'c_six_to_ten', 'values')]] are not in ALL in the [columns]"

如何选择要保存到csv文件的列？

Answer 1

应该是：

trans.to_csv('study10.csv' , encoding='utf-8', columns = ["reg_no", "st_name", "c_six_to_ten", "values"] )

你尝试的是一个包含单个元组的列表
