我得到了python错误TypeError：字符串索引必须是整数，而不是str

下面是我从JSON响应中得到的字典

{u'definitions': [{u'text': u'One venerated for experience, judgment, and wisdom.', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}, {u'text': u'Having or exhibiting wisdom and calm judgment.', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}, {u'text': u'Proceeding from or marked by wisdom and calm judgment:  sage advice. ', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}, {u'text': u'Archaic   Serious; solemn.', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}, {u'text': u'Any of various plants of the genus Salvia, especially S. officinalis, having aromatic grayish-green, opposite leaves. Also called ramona.', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}, {u'text': u'The leaves of this plant used as a seasoning.', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}, {u'text': u'Any of various similar or related plants in the mint family.', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}, {u'text': u'Sagebrush.', u'attribution': u'from The American Heritage\xae Dictionary of the English Language, 4th Edition'}]}

我试图使用以下代码语句访问前两个“文本”：

text1 = [body["definitions"][0]["text"],
         body["definitions"][1]["text"]]

我得到了我需要的字符串

但实际的问题是，当我在我的raspberry Pi 2上运行相同的代码时，我得到以下错误

TypeError:字符串索引必须是整数，而不是str

任何帮助都将不胜感激。

body[“definitions”]

返回一个字符串，请说“hello”，因此如果您写：

body["definitions"]["0"]

"hello"[0]

这相当于：

"hello"["0"]

这会产生错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: string indices must be integers

你会得到：

'h'

---

在raspberry PI上，您请求用户输入，而所有用户输入都是一个字符串。尝试以下操作：

data=[10,20]

，然后

print（data[“0”]）

它可以正常工作，如图所示，将该字典分配给

正文。你确定你真的创建了一个字典，而不是仅仅尝试直接使用JSON响应（这是一个字符串，就像通过网络接收到的其他任何东西一样）？您需要显示在Pi上实际运行的实际代码，还需要准确显示如何提供数据。
