Python实现爬取大陆大学排名，嵩天老师课程示例举一反三

代码

import requests
from bs4 import BeautifulSoup
import bs4

def getHTMLText(url):
    try:
        r = requests.get(url, timeout=30)
        r.raise_for_status()
        r.encoding = r.apparent_encoding
        return r.text
    except:
        return ""

def fillUnivList(ulist, html):
    soup = BeautifulSoup(html, "html.parser")
    for tr in soup.find('tbody').children:
        if isinstance(tr, bs4.element.Tag):
            tds = tr('td')
            if tds[2].string == '大陆':
                ulist.append([tds[0].string, tds[1].string, tds[3].string])


def printUnivList(ulist, num):
    print(f'{"大陆排名":^10}\t{"中国排名":^10}\t{"学校名称":{chr(12288)}^6}\t{"总分":^16}')
    count = 0
    for i in range(num):
        count += 1
        u = ulist[i]
        print(f"{count:^16}\t{u[0]:^6}\t{u[1]:{chr(12288)}^10}\t{u[2]:^10}")


def main():
    uinfo = []
    url = 'http://www.zuihaodaxue.com/Greater_China_Ranking2019_3.html'
    html = getHTMLText(url)
    fillUnivList(uinfo, html)
    printUnivList(uinfo, 25)  # 25 univs


main()

结果如下
