我得到python错误类型错误：字符串索引必须是整数，而不是s

Question

下面是我从JSON响应中获得的字典

{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'}]}

我尝试使用以下代码语句访问前两个“文本”：

^{pr2}$

我有我需要的绳子。在

但实际的问题是，当我在我的raspberry pi2上运行相同的代码时，我得到以下错误

TypeError: string indices must be integers, not str

任何帮助都将不胜感激。在

Answer 1

body["definitions"]正在返回一个字符串，请说“hello”，因此如果您写入：

body["definitions"]["0"]

相当于：

^{pr2}$

从而产生错误：

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

但如果你写：

"hello"[0]

你会得到：

'h'
