我收到python錯誤TypeError：字符串索引必須是整數，而不是str

Question

以下是我從JSON響應中獲得的字典

{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'}]}

我正在嘗試使用此代碼語句訪問前兩個“文本”：

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

我得到了我需要的琴弦。

但是實際的問題是，當我在樹莓派2上運行相同的代碼時，出現以下錯誤

TypeError：字符串索引必須是整數，而不是str

任何幫助，將不勝感激。

Answer 1

body["definitions"]返回一個字符串，說“ hello”，因此，如果您編寫：

body["definitions"]["0"]

等效於：

"hello"["0"]

產生錯誤：

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

但是，如果您寫：

"hello"[0]

你得到：

'h'
