我收到python错误TypeError：字符串索引必须是整数，而不是str

Question

Below is the dictionary that I get from a JSON response

{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'}]}

I am trying to access the first two 'text' by using this code statement:

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

I get the strings that I need.

But the actual problem is that when I run the same code on my raspberry Pi 2, I get the following error

TypeError: string indices must be integers, not str

Any help would be appreciated.

Answer 1

body["definitions"] is returning a string, say "hello", so if you write:

body["definitions"]["0"]

that is equivalent to:

"hello"["0"]

which produces the error:

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

But if you write:

"hello"[0]

you get:

'h'
