我认为我的代码是正确的，但为什么结果显示错误？ 根本不应该有错误值。 我的目标是从列选择“RT”、“RW”、“Kelurahan”中创建一个名为“Status Zonasi”的新列，其值为 ['Zonasi 1', 'Zonasi 2', 'Zonasi 3', 'Belum Diketahui'] '，'贾鲁尔达夫塔'。

这是我的 df 的样本

Answer 1

1. 在条件中使用列表时，应使用'in'。 前任。 w 在 [0,1,2...]

2. 确保列的数据类型正确。

3. 最后，我从您的示例 df 中看不到任何符合“zonasi 1”和“zonasi 2”条件的行。 如果上述 2 没有帮助，您能否分享您的数据的另一个子集，包括您希望 'status_zone' 为 'zonasi 1 或 2' 的一些行
