Python字典类型错误

Question

我有一个字典，长得像这样：

Dict = { "key1" : {"subkey1" : "value1" , "subkey2" : "value2" , 

         "key2" : {"subkey1" : "value3" , "subkey2" : "value4 }

我基本上想要检查一些值，像这样：

if (Dict[key][any_subkey] == "value"):

   do something....

但是我遇到了一个错误：TypeError：列表的索引必须是整数，而不是字符串……

有没有人能帮我解决这个问题呢？

Answer 1

像这样吗？

>>> Dict = { "key1" : {"subkey1" : "value1" , "subkey2" : "value2" ,
... 
...                    "key2" : {"subkey1" : "value3" , "subkey2" : "value4" }
...                              }
...          }
>>> print Dict["key1"]["key2"]["subkey2"] == "value4"
True

Answer 2

这个对我有效：

>>> Dict = { "key1" : {"subkey1" : "value1" , "subkey2" : "value2"} , 
...          "key2" : {"subkey1" : "value3" , "subkey2" : "value4" }}
>>> Dict["key1"]
{'subkey2': 'value2', 'subkey1': 'value1'}
>>> Dict["key1"]["subkey1"]
'value1'
>>> 

你检查过你的语法吗？
