问题描述

我是python 2 天的新手，我收到一条错误消息can only concatenate str (not "list") to str，我似乎无法解决问题，请尽快提供反馈，所以如果你能给我一些帮助，我将非常感激 thx。

这是错误信息

    print("                                                       " + characteristic)

解决方案

欢迎使用 StackOverflow，欢迎使用 Python！

您已将特征定义为列表，然后将几个特征（字符串）附加到列表中。

所以你不能打印列表——把它想象成一个容器。您需要打开容器并打印容器中的每个项目。

我建议您将其命名为特征而不是特征。

然后你可以写

for each characteristic in characteristics:
    print(characteristic)

您可以使用特征 [0]、[1] 等访问列表中的各个特征。
