typeError：只能将str（不是“list”）连接到str

Question

我是 python 新手，我收到一条错误消息，只能将 str（不是“列表”）连接到 str 我似乎无法解决问题，请尽快提供反馈，如果您能给我一些帮助，我将非常感谢thx。 我尝试循环相同以从列表中选择数字，但它发送以下错误。

这是错误信息

Answer 1

实际上，您将list 分配给变量mobile 为

mobile = ["Geeks\n", "for\n", "Geeks\n"]

并在此处将其与字符串连接如下-

request = {
    ...
    "PartyA": "1" + mobile,
    ...
    "PhoneNumber": "1" + mobile,
    ...
}
