In this line you need to pass a dictionary

data = urllib.parse.urlencode({"email":"qwerty@yahoo.com"})

but in your case this line is not necesary

response = urllib.urlopen(url[0], url[1])

In tray to reconstruct your part of code and get this succesfuly run for me

method = "POST"

from urllib import parse
from urllib import request


urlOpener = request.build_opener( request.HTTPCookieProcessor() )

url = 'http://localhost/pytest.php?email=xyz@abc.com'


if method == "POST":
    urlOpener.addHeaders = [('Content-Type', 'application/x-www-form-urlencoded')]
    url = url.split("?")
    data = url[1]
    urlOpener.addHeaders = [('Content-Length', str(len(data)))]
    response = request.urlopen(url[0], data)
