"socket.gaierror: [Errno 8] nodename nor servname provided, or not known"

[tucktuck9]

I'm working locally in Visual Studio on a simple Python program that prompts the user for a URL, then parses all of the anchor <a> tags. I'm using https://www.google.com to test. I suspect that it may have something to do with my imports/modules and the version of Python I'm using, which is python3. Can someone help?

I can run the code successfully in external tools, but not locally. Here is the error I receive:

Error:
Traceback (most recent call last):
  File "/Users/MYCOMPUTERNAME/Desktop/code3/_ex-12.1.py", line 9, in <module>
    from urllib.request import urlopen
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 88, in <module>
    import http.client
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/http/client.py", line 1342, in <module>
    import ssl
  File "/Users/MYCOMPUTERNAME/Desktop/code3/ssl.py", line 8, in <module>
    HOST = socket.getaddrinfo(HOST, PORT)[0][4][0]
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/socket.py", line 918, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 8] nodename nor servname provided, or not known

I have checked to see whether all of my modules were installed correctly with pip install {module}. The names and versions are below.

Name: requests
Version: 2.20.1
...
Name: urllib3
Version: 1.24.3
...
Name: bs4
Version: 0.0.1
...
Name: beautifulsoup4
Version: 4.9.0

Here is my code.

from urllib.request import urlopen
from bs4 import BeautifulSoup
import ssl

# Ignore SSL certificate errors
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

url = input('Enter - ')
html = urlopen(url, context=ctx).read()

soup = BeautifulSoup(html, "html.parser")

# Retrieve all of the anchor tags
tags = soup('a')
for tag in tags:
    # Look at the parts of a tag
    print('TAG:', tag)
    print('URL:', tag.get('href', None))
    print('Contents:', tag.contents[0])
    print('Attrs:', tag.attrs)

I'm using https://www.google.com as my input for testing pursposes. Here is what the actual output should be (as I have verified in external tools).
