今天终于静下心来学习python爬虫了，写了一个爬取猫眼top100榜单电影的小爬虫，效率不高，下次一定加油。

一张效果图（1~100）

都是上学期学过的，现在复习复习

上代码

import requests

from bs4 import BeautifulSoup

import urllib

def download(url, num_retries=2):

try:

headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3278.0 Safari/537.36'}

html = requests.get(url, headers=headers)

'''html.encoding=gb2312'''

except Exception as e:

print ('Download error:', e.reason)

html = None

if num_retries > 0:

if 500 <= html.status_code < 600:

return download(url, num_retries-1)

return html

def tiqu(html):

contents = []

bsobject = BeautifulSoup(html, "lxml")

caption = bsobject.findAll('p',{"class":'board-content'})[0].string

for lists in bsobject.findAll('dl',{'class':'board-wrapper'})[0]:

score = ''

content = []

if len(lists) == 1:

continue

content.append(lists.find('i').string)

test = lists.findAll('p',)

for aa in test:

bb = str(aa.string)

bb = bb.replace('\n','').strip()

if bb == 'None':

continue

content.append(bb)

for num in test[3]:

score = score + num.string

content.append(float(score.strip()))

contents.append(content)

return caption, contents

def getUrl(url, html):

urllist = []

listobject = BeautifulSoup(html, 'lxml')

urlone = listobject.findAll('a', {"class":'page_2'})[0].attrs['href'][:-2]

for num in range(0,100,10):

urls = urlone + str(num)

urllist.append(urllib.parse.urljoin(url, urls))

return urllist

def main():

contents = []

url = "http://maoyan.com/board/4"

html = download(url)

urllist = getUrl(url, html.text)

for url in urllist:

html = download(url)

caption , content = tiqu(html.text)

for con in content:

contents.append(con)

for con in contents:

print(con)

if __name__ == '__main__':

main()

看起来效果不好，还是上传文件吧
