      }
   }

```

and I want to get this:

```
{
         "sentences": [
            {
               "words": [
                  [
                     "Antigen",
                     {
                        "PartOfSpeech": "NN",
                        "CharacterOffsetEnd": "7",
                        "Lemma": "antigen",
                        "NamedEntityTag": "O",
                        "CharacterOffsetBegin": "0"
                     }
                  ],
                  [
                     "of",
                     {
                        "PartOfSpeech": "IN",
                        "CharacterOffsetEnd": "10",
                        "Lemma": "of",
                        "NamedEntityTag": "O",
                        "CharacterOffsetBegin": "8"
                     }
                  ],
                  [
                     "Bordetella",
                     {
                        "PartOfSpeech": "NN",
                        "CharacterOffsetEnd": "21",
                        "Lemma": "bordetellum",
                        "NamedEntityTag": "PERSON",
                        "CharacterOffsetBegin": "11"
                     }
                  ]
               ],
               "indexeddependencies": [],
               "parsetree": [],
               "text": "Antigen of Bordetella",
               "dependencies": []
            }
         ]
      }

```

To obtain that I write this:

```
    with open(pathOfTheJsonFIle) as f:
        data = json.load(f)
    print(data['Antigen of Bordetella']) 

```

but i get this error: *list indices must be integers, not str*

This file is quite big (there are more than 10.000 items) so I would like to find the item *Antigen of Bordetella* using some index (and not writing data[2], for example)
