【问题描述】：
这是我第一次使用 JSON，我被挂在这里。
我想在 Python 中使用 json.loads(tackles) 解析这个名为 tackles 的 JSON 字符串并得到错误 TypeError: expected string or buffer
在此之后我使用了json.loads(str(tackles))，但它失败并出现以下错误ValueError: Expecting property name: line 1 column 2 (char 1)
那么我到底需要改变什么才能让它工作呢？
最好的例子是显示我如何在团队名称旁边打印所有 tackleWontotal 值。
这是 JSON 字符串：

现在我能够解决问题。感谢所有回复的人，你们的回复对我帮助很大。

-
键上的
u前缀不是有效的 json。这看起来像是有人漂亮地打印了一本 python 字典。 -
正如其他人指出的那样，它不是有效的 json。这些值需要用双引号括起来。您可以使用它来验证您的 json jsonlint.com
