TypeError: string indices must be integers (Python)
提问by Martin
I am trying to retrieve the 'id' value : ad284hdnn.
我正在尝试检索“id”值：ad284hdnn。
I am getting the following error : TypeError: string indices must be integers
我收到以下错误： TypeError: string indices must be integers
data = response.json()
print data
for key in data['result']:
print key['id']
Here is the json that is returned when print the data string.
这是打印数据字符串时返回的json。
{u'meta': {u'httpStatus': u'200 - OK', u'requestId': u'12345'}, u'result': {u'username': u'[email protected]', u'firstName': u'joe', u'lastName': u'bloggs', u'accountStatus': u'active', u'id': u'ad284hdnn'}}

data['result']is a dictionary. Iterating over dictmeans iterating over its keys. Therefore keyvariable stores a string. That's why key['id']raises TypeError: string indices must be integers.
data['result']是字典。迭代dict意味着迭代它的键。因此key变量存储一个字符串。这就是为什么key['id']提出TypeError: string indices must be integers.
