Pass parameter in URL

Personal I am using the code below to query on google latitude and longitude based address, I would like to know how do I pass to the URL address in parameter form? The code below works perfectly because I'm passing the fixed parameters:

import urllib.request 
import json
>     
>     
>     with urllib.request.urlopen("https://maps.googleapis.com/maps/api/geocode/json?address=140+Rua+Cica,Curitiba%C3%AD,+PR&key=AIzaSyBKP7Lndi1G9-O1NpCwV7y_QV5i7tMBx9o") as url:
>     with 
>     
>         s = url.read()
>     jsonResponse = json.loads(s)
>     test = json.dumps([s['geometry']['location'] for s in jsonResponse['results']], indent=3)
>     print(test)

But when I try to pass the parameters to error URL:

a = 140 b = 'Cica Street' c = 'Curitiba' d = 'PR'

with urllib.request.urlopen("https://maps.googleapis.com/maps/api/geocode/%/%/%/%/json?address= % a+% b,% c%C3%AD,+d&key=AIzaSyBKP7Lndi1G9-O1NpCwV7y_QV5i7tMBx9o") as url:

The error:
