我想知道如何用美丽的汤提取这些数据并将其放入数据框pandas中。我已经提取了 HTML 页面，直到这部分，但我无法继续访问包含许多字典的列表，有人知道如何仅提取列表“数据信息”？

答案 0 :(得分：0)
这有点棘手，但可以在 json 的帮助下完成：
import json
from bs4 import BeautifulSoup as bs
html = """[your html above]"""
soup = bs(html,'lxml')
target = soup.select_one('[data-infos]')["data-infos"]
items = json.loads(target)
df = pd.json_normalize(items) #you need this because the data contains nested dictionaries
df
输出（请原谅格式）：
date wind.velocity wind.gust wind.direction_degrees wind.direction temperature.temperature rain.precipitation pressure.pressure humidity.relativeHumidity uv.uv
0 2021-01-13 00:00:00 15 26.02 46.8 NE 25 0.0 1009 61 16
