简单获取网页源代码

#-*-coding:utf-8-*-
import requests
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36'}
#伪装
url = 'http://www.bilibili.com/'
html = requests.get(url, headers=headers)
print html.text

伪装可以在浏览器中审查元素，network中随便选一个查看，看最底下的User-Agent就行了，顺便一提hearders是个字典。
