How to get cookies from urllib.request?

Question

How to get cookie from an urllib.request?

import urllib.request
import urllib.parse

data = urllib.parse.urlencode({
    'user': 'user',
    'pass': 'pass'
})
data = data.encode('utf-8')

request = urllib.request.urlopen('http://example.com', data)
print(request.info())

request.info() returns cookies but not in very usable way.

response.info() is a dict type object. so you can parse any info you need. Here is a demo written in python3:

from urllib import request
from urllib.error import HTTPError

# declare url, header_params 

req = request.Request(url, data=None, headers=header_params, method='GET')
try:
    response = request.urlopen(req)

    cookie = response.info().get_all('Set-Cookie')
    content_type = response.info()['Content-Type']
except HTTPError as err:
    print("err status: {0}".format(err))
    return

You can now, parse cookie variable as your application requirement.
