Output docs.google.com confirm code with python

This is python code to get confirm code from document 0BxmEiwnrWfmmTjlIVmE0S01YM0U:

from mechanize import Browser
import re
br = Browser()

br.set_handle_robots( False )
br.addheaders = [('User-agent', 'Firefox')]

id = "0BxmEiwnrWfmmTjlIVmE0S01YM0U"

r = br.open('http://docs.google.com/uc?id='+id+'&export=download')

regex = 'download&amp;confirm=(.+?)&amp;id'
pattern = re.compile(regex)
html = r.read()
confirm = re.findall(pattern,html)
print confirm

download&confirm= and &id is just the identificator for start and end text 1:1 from html source.
There are no special characters.

(.+?) just says "Take the content between!"

Next one will print also filename

from mechanize import Browser
import re
br = Browser()

br.set_handle_robots( False )
br.addheaders = [('User-agent', 'Firefox')]

id = "0BxmEiwnrWfmmTjlIVmE0S01YM0U"

r = br.open('http://docs.google.com/uc?id='+id+'&export=download')

html = r.read()

confirm = re.findall('download&amp;confirm=(.+?)&amp;id',html)

filename = re.findall(id+'">(.+?)</a> \(',html)

print confirm

print filename

there are reg expression special character \(in id+'">(.+?)</a> \(
