用python爬取网页表格数据，供大家参考，具体内容如下

from bs4 import BeautifulSoup import requests import csv import bs4 #检查url地址 def check_link(url): try: r = requests.get(url) r.raise_for_status() r.encoding = r.apparent_encoding return r.text except: print('无法链接服务器！！！') #爬取资源 def get_contents(ulist,rurl): soup = BeautifulSoup(rurl,'lxml') trs = soup.find_all('tr') for tr in trs: ui = [] for td in tr: ui.append(td.string) ulist.append(ui) #保存资源 def save_contents(urlist): with open("D:/2016年中国企业500强排行榜.csv",'w') as f: writer = csv.writer(f) writer.writerow(['2016年中国企业500强排行榜']) for i in range(len(urlist)): writer.writerow([urlist[i][1],urlist[i][3],urlist[i][5]]) def main(): urli = [] url = "http:///news/463071.html" rs = check_link(url) get_contents(urli,rs) save_contents(urli) main()
