Python爬取爬取明星关系并写入csv文件
今天用Python爬取了明星关系,数据不多,一共1386条数据,代码如下:
import requests from bs4 import BeautifulSoup import bs4 import csv def getHTMLText(url): try: kv = {'user-agent': 'Mozilla/5.0'} # 请求头;指定访问浏览器为Mozilla5.0版本的浏览器 r = requests.get(url) r.raise_for_status() #如果状态不是200,引发HTTPError异常 r.encoding = r.apparent_encoding return r.text except: return "产生异常" def fillUnivList(ulist,html): soup = BeautifulSoup(html,"lxml") for lis in soup.find_all('li', {'liodd', 'lieven'}): if isinstance(lis, bs4.element.Tag): spans = lis('span') ulist.append([spans[0].text.strip(), spans[1].text.strip(), spans[2].text.strip()]) #print(spans[0].text.strip()," ",spans[1].text.strip()," ",spans[2].text.strip(),) with open('star.csv', 'a', newline='')as f: csv_writer = csv.writer(f) csv_writer.writerows(ulist) f.close() #print(ulist) if __name__ == '__main__': print("爬虫开始") for page in range(1,100): url = "https://www.1905.com/mdb/relation/list/s0t0p" + str(page) + ".html" html = getHTMLText(url) ulist=[] fillUnivList(ulist,html) print("爬虫结束")
