豆瓣电影搜索爬虫程序，爬虫小程序，适合初学者

最近在学python，之前用Python写过简单的图片爬取，今天想着用python爬一下豆瓣的电影，就有了下面的程序：

#coding:utf-8
#coding:utf-8
import re
import sys
import urllib
from bs4 import BeautifulSoup
def movieSearch():
<span style="white-space:pre">	</span>douBanSearchurl = "http://movie.douban.com/subject_search?search_text="
<span style="white-space:pre">	</span>data = urllib.urlopen(douBanSearchurl+movieName).read()
<span style="white-space:pre">	</span>r = re.findall(r'<a class="nbg" href=(.*?) onclick',data)
<span style="white-space:pre">	</span>realy_url = re.sub('"','',r[0])
<span style="white-space:pre">	</span>movieData = urllib.urlopen(realy_url).read()
<span style="white-space:pre">	</span>soup = BeautifulSoup(movieData)
<span style="white-space:pre">	</span>movieSummary = soup.find_all("span",{'property':'v:summary'})
<span style="white-space:pre">	</span>#movieSummaryText = re.findall(r'<span property="v:summary" class="">(\W*.*\W*.*?)</span>',movieData)
<span style="white-space:pre">	</span>movie = re.findall(r'name="title" value="(.*?)"',movieData)
<span style="white-space:pre">	</span>people = re.findall(r'name="desc" value="(.*?)"',movieData)
<span style="white-space:pre">	</span>imdb = re.findall(r'</span> <a href="(.*?)" target=',movieData)
<span style="white-space:pre">	</span>Time = re.findall(r'<span property="v:runtime" content="109">(.*?)</span>',movieData)
<span style="white-space:pre">	</span>print u"IMDB电影网链接"
<span style="white-space:pre">	</span>print imdb[0]
<span style="white-space:pre">	</span>print u"豆瓣电影链接"
<span style="white-space:pre">	</span>print  realy_url
<span style="white-space:pre">	</span>print '*'*100
<span style="white-space:pre">	</span>print movie[0].decode('utf-8').encode('gbk')
<span style="white-space:pre">	</span>print people[0].decode('utf-8')
<span style="white-space:pre">	</span>print u"电影简介"
<span style="white-space:pre">	</span>print '*'*100
<span style="white-space:pre">	</span>print movieSummary[0].encode('utf-8').decode('utf-8').encode('gbk')
if __name__=='__main__':
<span style="white-space:pre">	</span>while(1):
<span style="white-space:pre">		</span>arg = raw_input("请选择功能:\n1:电影搜索\n2:退出\n".decode('utf-8').encode('gb2312'))
<span style="white-space:pre">		</span>if arg=='1' :
<span style="white-space:pre">			</span>movieName=raw_input("请输入电影名:  ".decode('utf-8').encode('gb2312')).strip()
<span style="white-space:pre">			</span>print u"开始搜索"
<span style="white-space:pre">			</span>movieSearch()
<span style="white-space:pre">		</span>else:
<span style="white-space:pre">			</span>print u"退出程序"
<span style="white-space:pre">			</span>break;
<span style="white-space:pre">			</span>

在调试过程中，遇到了两个头疼的问题：

1、beautifulSoup编码与CMD编码不匹配，beautifulSoup得到的网页信息均为Unicode，但是cmd不支持Unicode只有gbk，中文显示就成了很大问题了，所以就用了最笨的办法，通过转码来实现，目前还没找到更好的办法，如果有请指点下。

2、在写正则表达式时，不知道<br\>如何匹配，特别是对于网页文字有换行分段的形式，该如何匹配？
