这个JSON字符串有什么问题？

标签： python json python-2.7 parsing web-scraping

这是我第一次使用JSON而且我在这里挂了。

我想在Python中使用tackles解析名为json.loads(tackles)的JSON字符串，并收到错误TypeError: expected string or buffer

在此之后我使用了json.loads(str(tackles))，但失败了以下错误ValueError: Expecting property name: line 1 column 2 (char 1)

那么究竟需要改变什么才能使其有效？ 最棒的是一个示例，说明如何打印团队名称旁边的所有tackleWontotal值。

这是JSON字符串：

现在我能够解决这个问题。感谢所有回复的人，您的回复对我来说是一个很大的帮助。

答案 0 :(得分：0)

事实是，这不是一个合适的JSON字符串。 u'用于Python unicode字符串对象，可能在某处，您的原始JSON被转换为Python对象，然后进行字符串化。

检查更改的位置，然后将其消除，以便为load（）方法

提供正确的JSON

答案 1 :(得分：0)

正如其他人所说，这不是JSON;除其他事项外，JSON需要将其键引用为双引号（不是单引号），并禁止使用Python u前缀。

如果这实际上是您获得的数据，那么您最好使用ast.literal_eval。 （Docs here.）

那就是说，当你说你试图运行json.loads(str(tackles))时，我会再往前看。

str(tackles)不会产生JSON; json.dumps(tackles)。如果您只想测试JSON生成/解析，请尝试json.loads(json.dumps(tackles))。

答案 2 :(得分：0)

或只是

parsedtackles = str (json.dumps(tackles))
