# /usr/bin/python
#coding:utf-8
__author__ = 'eyu Fanne'

import requests,re
from bs4 import BeautifulSoup

move_url = 'https://movie.douban.com/'

def Robot():
    res_url = requests.get(move_url)
    print res_url.status_code
    soup = BeautifulSoup(res_url.text,'lxml')
    print soup.title
    soup_a = soup.find_all("a",class_="item")
    for i in soup_a:
        print i
    print soup_a



if __name__=='__main__':
    Robot()
