如何使用异常表格从选举网站上抓取数据

首先，你得到的错误意味着你使用BeautifulSoup不正确。

您需要将来自 HTTP 客户端的响应传递给BeautifulSoup这样的：

import requests
from bs4 import BeautifulSoup

url = "https://results.texas-election.com/races"

headers = {
    "user-agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36",
}

response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, "html.parser")

其次重要的是，你不需要BeautifulSoup刮该页面。一切都回来了JSON。例如：

import requests

url = "https://results.texas-election.com/static/data/election/44146/246/Federal.json"

headers = {
    "user-agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36",
}
response = requests.get(url, headers=headers).json()

for race in response["Races"]:
    print(f"Results for {race['N']}")
    for candidate in race["Candidates"]:
        print(f"{candidate['N']} - {candidate['P']}: Votes {candidate['V']} - {candidate['PE']}%")
    print(f"Total votes: {race['T']}")
    print("-" * 80)

输出：

编辑：

要获取您提到的特定URL的数据，只需使用以下命令：

注意：这只是数据的一小部分，因为数据JSON很大。我添加了用于转储整个内容的代码，JSON以便您可以按照自己的方式解析它。

import json

import requests

url = "https://results.texas-election.com/static/data/election/44144/108/County.json"

headers = {
    "user-agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36",
}
response = requests.get(url, headers=headers).json()


with open("county_results.json", "w") as output:
    json.dump(response, output, indent=4, sort_keys=True)

for v in response.values():
    for id_, race_data in v["Races"].items():
        print(race_data["C"])

示例输出：

{'4250': {'id': 4250, 'N': 'KEN WISE (I)', 'P': 'REP', 'V': 0, 'PE': 0.0, 'C': '#E30202', 'O': 1, 'EV': 0}, '6015': {'id': 6015, 'N': 'TAMIKA "TAMI" CRAFT', 'P': 'DEM', 'V': 0, 'PE': 0.0, 'C': '#007BBD', 'O': 2, 'EV': 0}}
{'2966': {'id': 2966, 'N': 'BRENDA MULLINIX (I)', 'P': 'REP', 'V': 0, 'PE': 0.0, 'C': '#E30202', 'O': 1, 'EV': 0}, '6224': {'id': 6224, 'N': 'JANET BUENING HEPPARD', 'P': 'DEM', 'V': 0, 'PE': 0.0, 'C': '#007BBD', 'O': 2, 'EV': 0}}
{'2967': {'id': 2967, 'N': 'MAGGIE JARAMILLO (I)', 'P': 'REP', 'V': 0, 'PE': 0.0, 'C': '#E30202', 'O': 1, 'EV': 0}, '3708': {'id': 3708, 'N': 'TAMEIKA CARTER', 'P': 'DEM', 'V': 0, 'PE': 0.0, 'C': '#007BBD', 'O': 2, 'EV': 0}}
and much, much more...

我是怎么找到的JSON？

我检查了浏览器开发工具的网络选项卡。:)
