python - 如何创建多级json文件，然后从python读取特定值？

Question

我正在开发一个测验式的程序来学习阿拉伯语。我现在需要从代码中删除问题并将它们存储在外部文件中 - 我正在考虑 .JSON。然而，我在从 python 访问某些问题或文件的部分时遇到困难，我不确定是否是因为我没有正确格式化我的 .JSON 文件，或者我的代码是否有错误。我已将两者都包含在下面。最终，我计划开设多节类(class)，每节课有 3-4 个部分，其中包含 .JSON 文件中的问题。目前我只上了一节包含三个部分的课，只是为了确保我做对了事情。我在这里查看了另一个问题( How to read multi-level json )，但解决方案似乎对我不起作用。

如果我现在尝试运行代码，我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'

这是我的代码:

import json
import random

with open("C:\\LearningArabic\\LiblibArriby\\Lessons\\Arabic_Lessons.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"])

print(data["lesson 1"]["part two"])

for i in data["lesson 1"][0]["part two"]:
    print (i["answer"])

question = (data["lesson 1"]["part one"])
questions = random.choice(question)

print(questions.get("question"))

行:

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

可以工作并打印第一部分中的所有问题，但之后我收到上述错误。

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"
        }
    ]}
]}

Answer 1

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"])

按预期工作。 print(data["第一课"]["第二部分"]) 也有效。

您需要删除“lesson1:后面的方括号并整理变量的索引
