Whenever I try to construct a string based on self.live_server_url, I get python TypeError messages. For example, I've tried the following string constructions (form 1 & 2 below), but I experience the same TypeError. My desired string is the Live Server URL with "/lists" appended. NOTE: the actual test does succeed to create a server and I can manually access the server, and more specifically, I can manually access the exact URL that I'm trying to build programmatically (e.g. 'http://localhost:8081/lists').
TypeErrors occur with these string constructions.
# FORM 1
lists_live_server_url = '%s%s' % (self.live_server_url, '/lists')
# FORM 2
lists_live_server_url = '{0}{1}'.format(self.live_server_url, '/lists')
self.browser.get(lists_live_server_url)
There is no python error with this form (nothing appended to string), albeit my test fails (as I would expect since it isn't accessing /lists).
self.browser.get(self.live_server_url)
Here is the python error that I'm getting.

Am I unknowingly attempting to modify the live_server_url, which is leading to these TypeErrors? How could I programmatically build a string of live_server_url + "/lists"?
Here is the test that I am attempting...
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from django.test import LiveServerTestCase
class LiveNewVisitorTest(LiveServerTestCase):
def setUp(self):
self.browser = webdriver.Chrome()
self.browser.implicitly_wait(3)
def tearDown(self):
self.browser.close()
def test_can_start_a_list_and_retrieve_it_later(self):
#self.browser.get('http://localhost:8000/lists')
#self.browser.get('http://www.google.com')
#lists_live_server_url = '%s%s' % (self.live_server_url, '/lists')
#lists_live_server_url = '{0}{1}'.format(self.live_server_url, '/lists')
lists_live_server_url = self.live_server_url
self.browser.get(lists_live_server_url)
self.assertIn('To-Do', self.browser.title)
header_text = self.browser.find_element_by_tag_name('h1').text
self.assertIn('To-Do', header_text)
