Python SSLCertVerificationError When running a unittest

Question

I am currently working on a final exam for a python programming course and can't seem to get past the error below (SSLCertVerificationError) during the unit test. I am attempting to use pull text from a url by a tag and id. I've tried many solutions like running the "install certificates.command" and some answers said it could be a server issue. My instructor said that we cannot use them as a resource so I wanted to exhaust all options before reaching out to them.

Code -

def __init__(self, src, _src_type = 'discover', _content = 'none', _orig_content = 'none'):
        self.src = src
        self._srctype = _src_type
        self._content = None
        self._orig_content = None 

        if re.search('^http', src):
            self._src_type = 'url'
        elif re.search('txt$', src):
            self._src_type = 'path'
        else:
            self._src_type = 'text'

def set_content_to_tag(self, tag, tag_id=None):
        self.tag = tag
        self.tag_id = tag_id
        if self._src_type == 'url':
            r = requests.get(self.src)
            self._orig_content = r.text
        else:
            raise Exception('You are attempting to search an instance that is not a url')
        
        soup = BeautifulSoup(self._orig_content, 'html.parser')
        self._content = soup.findall(self.tag, self.tag_id).get_text()

Unittest -

import unittest

url = 'https://www.webucator.com/how-to/address-by-bill-clinton-1997.cfm'
path = 'pride-and-prejudice.txt'
text = '''The outlook wasn't brilliant for the Mudville Nine that day;
the score stood four to two, with but one inning more to play.
And then when Cooney died at first, and Barrows did the same,
a sickly silence fell upon the patrons of the game.'''

class TestTextAnalyzer(unittest.TestCase):
    def test_discover_url(self):
        ta = TextAnalyzer(url)
        self.assertEqual(ta._src_type, 'url')
    def test_discover_path(self):
        ta = TextAnalyzer(path)
        self.assertEqual(ta._src_type, 'path')
    def test_discover_text(self):
        ta = TextAnalyzer(text)
        self.assertEqual(ta._src_type, 'text')
    def test_set_content_to_tag(self):
        ta = TextAnalyzer(url)
        ta.set_content_to_tag('div','content-main')
        self.assertEqual(ta._content[0:23], 'Address by Bill Clinton')
