【爬虫实战】用python爬今日头条热榜TOP50榜单！

import requests
from bs4 import BeautifulSoup
import pandas as pd
 
# 设置请求头，模拟浏览器访问
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
 
def get_data(url):
    response = requests.get(url, headers=headers)
    soup = BeautifulSoup(response.text, 'lxml')
    data = soup.find_all('div', class_='title')
    rank = [i.span.get_text() for i in soup.find_all('div', class_='num')]
    names = [i.a.get_text() for i in data]
    hrefs = ['https://www.toutiao.com' + i.a.get('href') for i in data]
    return rank, names, hrefs
 
def main(url):
    rank, names, hrefs = get_data(url)
    data = pd.DataFrame(list(zip(rank, names, hrefs)), columns=['排名', '名称', '链接'])
    print(data)
    data.to_csv('今日头条热榜.csv', index=False, encoding='utf-8')
 
if __name__ == '__main__':
    url = 'https://www.toutiao.com/hotwords/'
    main(url)

这段代码首先定义了请求头，用于模拟浏览器访问网页。get_data 函数用于获取网页数据，并通过BeautifulSoup进行解析。main 函数则是程序的主要逻辑，它调用get_data函数获取数据，并将数据存储在一个DataFrame中，最后将数据保存到CSV文件中。最后，在__name__为__main__时，执行主函数，开始爬取数据。
