Python 如何提取HTML表并导出json？

我有一个由表组成的HTML页面，我想导出JSON。 我正在使用BeautifulSoup解析HTML文件。 HTML文件

我相信这就是你想要的：

import json
from bs4 import BeautifulSoup as bs
from collections import defaultdict

soup = bs(your_html_above, 'html.parser')
items = soup.find_all("b")
target_dict = defaultdict(dict)

for item in items:
    if 'Pod' in item.text:
        pod = item.text.strip()    
    if 'Disk' in item.text:
        disk = item.text
        bas = item.find_next('b')
        target_dict[pod][disk] = bas.text
dict_json = json.dumps(target_dict)
print(dict_json)

输出：

{"Pod 0": {"Disk 1": "2.21", "Disk 2": "2.01"}, "Pod 1": {"Disk 1": "1.89", "Disk 2": "1.00"}, "Pod 2": {"Disk 1": "2.08", "Disk 2": "2.15"}}

提供您迄今为止尝试过的代码

{"Pod 0": {"Disk 1": "2.21", "Disk 2": "2.01"}, "Pod 1": {"Disk 1": "1.89", "Disk 2": "1.00"}, "Pod 2": {"Disk 1": "2.08", "Disk 2": "2.15"}}
