python - 如何检索两个字符串之间的值

Question

我有一个 json 文件。我想使用 python 检索两个字符串之间的值。

{
    "101": {

        "set": [
            "1012", 
            "some text a."
        ], 
        "tag": "tagtext"
    }, 
    "1027": {
        "slide": [
            "1013757", 
            "x"
        ]
    }, 
    "1014220": {
        "set": [
            "1018420", 
            "some text."
        ], 
        "ans": "4th"
    }, 
    "1019660": {
        "set": [
            "1031920", 
            "Some text b"
        ], 
        "tag": "tagtext"
    }, 
    "1034280": {
        "set": [
            "1040560", 
            "some text"
        ], 
        "interact": "intertext"
    },

我想提取set和tag之间的数据:

输出应该是:“一些文字。”“一些文本 b。”

Answer 1

将输入解析为 JSON 并检查是否存在 标签。

import json

with open("j.json") as f:
    j = json.load(f)

for k, v in j.items():
    try:
        s = v["set"]
        t = v["tag"]
        print(s[1])
    except:
        # no tag
        pass

输出:

some text a.
Some text b
