用python爬虫链接https://www.shanghairanking.cn/rankings/bcur/2023 返回前30名大学

可以使用Python的requests和BeautifulSoup库来进行网页爬取和解析。以下是代码示例：

import requests
from bs4 import BeautifulSoup

# 发送HTTP GET请求，获取网页内容
url = 'https://www.shanghairanking.cn/rankings/bcur/2023'
response = requests.get(url)
html = response.text

# 使用BeautifulSoup解析网页内容
soup = BeautifulSoup(html, 'html.parser')

# 获取前30名大学名称和排名信息
table = soup.find('table', class_='rk-table')
rows = table.find_all('tr')[1:31]  # 排除表头行，只保留前30行
for row in rows:
    rank = row.find('td', class_='rk-rank').text.strip()
    name = row.find('a', class_='univ-name').text.strip()
    print(rank, name)
