python - 如何在 python 中组合 2 个列表中的数据以形成单个 JSON

Question

我有 2 csv文件(分号分隔)具有以下结构和示例数据:

文件 1:

qid;question
1.0;How can I find specific content
2.0;How do I modify content
2.0;How can I edit items
2.0;I need to change some answers
3.0;How do I troubleshoot and fix problems

文件 2:

qid;answer
1.0;Use the Filter feature to filter the items
2.0;Use the test tool to find your existing documents and edit them
3.0;Use the test tool to test a document

现在我想做的是形成一个 JSON包含来自两个文档的数据的结构，形成以下示例结构:

{
   "qna": [
      {
         "qid": "1.0",
         "q": [
            "How can I find specific content"
         ],
         "a": "Use the Filter feature to filter the items."

      },
      {
         "qid": "2.0",
         "q": [
            "How do I modify content","How do I edit items","I need to change some answers"
         ],
         "a": "Use the test tool to find your existing documents and edit them."
      },
      {
         "qid": "3.0",
         "q": [
            "How do I troubleshoot and fix problems"
         ],
         "a": "Use the test tool to test a document"

      }
]
}

正如你所看到的 JSON包含 list of list qna内 field 。此 list of list 中的每一项包含qid ，匹配相同的问题列表 qid ，并且答案匹配 qid .

我在阅读这些 2 csv 时编写了这段代码文件和成型2 list of lists :

qid_question_list = {}
qid_answer_list = {}

reader1 = csv.reader(csv_file1, delimiter=';')

next(reader1)

reader2 = csv.reader(csv_file2, delimiter=';')

next(reader2)

for qid,question in reader1:
    if qid not in qid_question_list:
        qid_question_list[qid] = list()
    qid_question_list[qid].append(question)

for qid,answer in reader2:
    if qid not in qid_answer_list:
        qid_answer_list[qid] = list()
    qid_answer_list[qid].append(answer)

当我执行上面的命令时，我得到以下 2 lists :

qid_question_list

{'1.0': ['How can I find specific content'], '2.0': ['How do I modify content','How do I edit items','I need to change some answers'], '3.0': ['How do I troubleshoot and fix problems']}

qid_answer_list

{'1.0': ['Use the Filter feature to filter the items'], '2.0': ['Use the test tool to find your existing documents and edit them'], '3.0': ['Use the test tool to test a document']}

现在我无法确定如何组合这 2 list of lists形成所需的JSON结构如上所示？

Answer 1

假设你手头有这两个字典

l1={'1.0': ['How can I find specific content'], '2.0': ['How do I modify content','How do I edit items','I need to change some answers'], '3.0': ['How do I troubleshoot and fix problems']}

l2={'1.0': ['Use the Filter feature to filter the items'], '2.0': ['Use the test tool to find your existing documents and edit them'], '3.0': ['Use the test tool to test a document']}

l = [ {"qid": k, "q": v, "a": l2[k]} for k,v in l1.items() ]

q={'qna': l }

print(q)

输出

{'qna': [{'qid': '1.0', 'q': ['How can I find specific content'], 'a': ['Use the Filter feature to filter the items']}, {'qid': '2.0', 'q': ['How do I modify content', 'How do I edit items', 'I need to change some answers'], 'a': ['Use the test tool to find your existing documents and edit them']}, {'qid': '3.0', 'q': ['How do I troubleshoot and fix problems'], 'a': ['Use the test tool to test a document']}]}
