python - 值错误: Expecting property name enclosed in double quotes in Python

Question

旧错误:我遇到了这个错误:

ValueError: Expecting property name enclosed in double quotes:

这是我的代码。我想将 String ResultPart 转换为字典:

 resultPart = '{"sentences": [{"parsetree": [], [("words": "Q", {"Lemma": "q", "NamedEntityTag": "O", "CharacterOffsetEnd": "1", "PartOfSpeech": "NN", "CharacterOffsetBegin": "0"})], "dependencies": [], "text": "Q", "parsetree": [], "indexeddependencies": []}]}'
 resultPart2 = json.dumps(resultPart)
 #result should be a dict
 result = json.loads(resultPart)

编辑:我更正了该部分，现在出现此错误:

TypeError: string indices must be integers

这是新代码:

 resultPart = "{'sentences': [{'words': [('Q', {'Lemma': 'q', 'NamedEntityTag': 'O', 'CharacterOffsetEnd': '1', 'PartOfSpeech': 'NN', 'CharacterOffsetBegin': '0'})], 'dependencies': [], 'text': 'Q', 'parsetree': [], 'indexeddependencies': []}]}"
 resultPart2 = json.dumps(resultPart)
 result = json.loads(resultPart2)

Answer 1

问题似乎出在以下行:

{
...
    "parsetree": [], [
    "words": "Q", {
        "Lemma": "q",
        "NamedEntityTag": "O",
        "CharacterOffsetEnd": "1",
        "PartOfSpeech": "NN",
        "CharacterOffsetBegin": "0"
    }],
...

}

它正在寻找[]之后的另一个键作为“parsetree”的值。因此，它需要类似于以下内容才能成为有效的 JSON。

{
...
    "parsetree": [], 
    "more_words": [
    "words": "Q", {
        "Lemma": "q",
        "NamedEntityTag": "O",
        "CharacterOffsetEnd": "1",
        "PartOfSpeech": "NN",
        "CharacterOffsetBegin": "0"
    }],
...

}
