Python词典“没有属性'__getitem__'

Question

Python的新手，似乎找不到这个答案。我正在尝试使用字典，如哈希或其他语言的关联数组，不确定这是否正确。

现在我正在做：

data['person'] = {'birthday': '01-01-1980'}

修改：data是从dict

返回的json.loads(response.text)

这会引发object has no attribute '__getitem__'错误。在SO上查看这个告诉我，我需要从我的 unicode 方法返回一个字符串，但这些只是简单的旧词典，没什么特别的。

Python v2.7.4

这很好用：

#!/usr/local/cpython-2.7/bin/python

data = {}
data['person'] = {'birthday': '01-01-1980'}

...所以数据可能不是你的情况下的字典。 SSCCE可能会有所帮助。
