I want to get few information for bunch of genes

I looked at UniProt and they give a similar python code to the following

import urllib,urllib2
    url = 'https://www.uniprot.org/uploadlists/'
    params = {
    'query': 'gene_exact:mapk1 AND organism:homo_sapiens AND reviewed:yes', 
    'format': 'tab', 
    'columns': 'id,ec,entry_name,genes'}

    data = urllib.urlencode(params)
    request = urllib2.Request(url, data)
    contact = "xxxx@outlook.com" 
    request.add_header('User-Agent', 'Python %s' % contact)
    response = urllib2.urlopen(request)
    header = response.readline()
    entries=response.read(200000)

I also used the above question C: UniProtKB - mapping gene name to ID (*_HUMAN ) using python2 and answer but it does not work for me , I get no output, is there any opinion or comment ?
