如何创建多级json文件，然后从python中读取特定值？

我正在为学习阿拉伯语做一个测验式的项目。我现在需要从代码中删除问题并将它们存储在一个外部文件中——我在思考.JSON。但是，我在从python访问某些问题或部分文件时遇到困难，我不确定这是因为我没有正确格式化.JSON文件，还是因为我的代码有错误。我已经包括了下面两个。最后，我计划上多节课，每节课有3-4个部分，在.JSON文件中有很多问题。目前我只有一节课，分为三个部分，以确保我做的事情是正确的。我在这里看了另一个问题（），但解决方案似乎对我不起作用

如果我现在尝试运行代码，会收到以下错误消息：

Traceback (most recent call last):
File "C:/LearningArabic/Test Programs/JSON open file test.py", line 10, in <module>
print(data["lesson 1"]["part two"])
KeyError: 'part two'

该行：

for i in data["lesson 1"]["part one"]:
    print (i["question"])

工作并打印第一部分中的所有问题，但在这之后，我得到了前面提到的错误

这是我的.JSON文件：

{"lesson 1":[
    {"part one": [
        {"question": "What is the meaning of 'واد' ?",
        "transliteration": "walid",
        "answer": "boy"
        },
        {"question": "What is the meaning of 'بنت' ?",
        "transliteration": "bint",
        "answer": "girl"
        },
        {"question": "What is the meaning of 'رخل' ?",
        "transliteration": "ragul",
        "answer": "man"
        },
        {"question": "What is the meaning of 'ست' ?",
        "transliteration": "sit",
        "answer": "woman"
        }
    ],
    "part two": [
        {"question": "What is the meaning of '2test1'?",
        "transliteration": "phonix",
        "answer": "21"
        },
        {"question": "What is the meaning of '2test2'?",
        "transliteration": "phonix2",
        "answer": "22"
        }
    ],
    "part three": [
        {"question": "What is the meaning of '3test1'?",
        "transliteration": "phonix",
        "answer": "31"
        },
        {"question": "What is the meaning of '3test2'?",
        "transliteration": "phonix2",
        "answer": "32"
        }
    ]}
]}

---

以下JSON文件：

{"lesson 1":
    {"part one": [
        {"question": "What is the meaning of 'ست' ?",
        "transliteration": "sit",
        "answer": "woman"
        }
    ],
    "part two": [
    ],
    "part three": [
        {"question": "What is the meaning of '3test2'?",
        "transliteration": "phonix2",
        "answer": "32"
        }
    ]}
}

使用以下python代码：

导入json

with open("test.json", "r", encoding = "utf-8-sig") as read_file:
    data = json.load(read_file)

for i in data["lesson 1"]["part one"]:
    print (i["question"])

for i in data["lesson 1"]["part two"]:
    print (i["answer"])

一切正常<代码>打印（数据[“第一课”][“第二部分”]）也可以

您需要删除

“第1课：

后面的方括号，并整理变量的索引

您可以使用嵌套循环像这样解析它：

for k in data["lesson 1"].keys():
    print(data["lesson 1"][k])
    for i in range(len(data["lesson 1"][k])):
        print(data["lesson 1"][k][i]["question"])

输出：

 [{'question': "What is the meaning of 'واد' ?", 'transliteration': 'walid', 'answer': 'boy'}, {'question': "What is the meaning of 'بنت' ?", 'transliteration': 'bint', 'answer': 'girl'}, {'question': "What is the meaning of 'رخل' ?", 'transliteration': 'ragul', 'answer': 'man'}, {'question': "What is the meaning of 'ست' ?", 'transliteration': 'sit', 'answer': 'woman'}]
    What is the meaning of 'واد' ?
    What is the meaning of 'بنت' ?
    What is the meaning of 'رخل' ?
    What is the meaning of 'ست' ?
    [{'question': "What is the meaning of '2test1'?", 'transliteration': 'phonix', 'answer': '21'}, {'question': "What is the meaning of '2test2'?", 'transliteration': 'phonix2', 'answer': '22'}]
    What is the meaning of '2test1'?
    What is the meaning of '2test2'?
    [{'question': "What is the meaning of '3test1'?", 'transliteration': 'phonix', 'answer': '31'}, {'question': "What is the meaning of '3test2'?", 'transliteration': 'phonix2', 'answer': '32'}]
    What is the meaning of '3test1'?
    What is the meaning of '3test2'?

使用jsonl文件怎么样？这样做会很容易。我确实使用了json文件，这是问题的最后一部分。我把它包括在这里，因为我担心可能会出现格式错误，这会给我错误消息。我是说使用jsonl文件，不同于json@piethon26，jsonl fi的好处是什么le vs a json文件？嵌套更少，我想我只是在考虑它，因为jsonl在技术上是json的json，所以每一行都可以是json。我删除了“lesson one”之后的“[”括号，得到了相同的错误。然后，我在最后删除了“]”括号（因此所有括号都将关闭）还是没有运气。我的文件中的代码正确吗？Markus，这对我来说是可行的。我的json.file文件中肯定有格式错误，但我将它简化为每个部分一个问题，然后它就成功了（还删除了括号）。然后我用其他问题重新构建了json.file，现在一切正常。谢谢！Luca，这确实有效，但没有回答我的问题。我的json.file中的格式有问题。不过，这是显示json.file部分的一种很酷的方式。
