python regex can't match,but matched in javascript with same parttern

Question

code is here: import re

    res = re.match('bbs1','http://bbs1.people.com.cn/userInfo.do?userNick=%E8%85%BE%E9%A3%9E%E4%B8%AD%E5%9B%BD%E9%BE%99')
    print(res)

It's print None,but when I change parttern to 'http',it matches; The same parttern in javascript can matched;

var url = 'http://bbs1.people.com.cn/userInfo.do?userNick=%E8%85%BE%E9%A3%9E%E4%B8%AD%E5%9B%BD%E9%BE%99'
url.match(/bbs/)
