Hey, let's break down your problem and fix it step by step—you've got two key issues here:

1. You're using the wrong GitHub URL #

The link https://github.com/UNAME/REPO/blob/master/test1.json points to GitHub's web page for displaying the file, not the raw JSON content. Even if you fixed the SSL error, you'd still get a JSON parsing failure because you're trying to load HTML as JSON.

To get the raw file, replace blob in the URL with raw:
https://github.com/UNAME/REPO/raw/master/test1.json

2. SSL Certificate Verification Failure #

This error happens because your local Python environment can't verify GitHub's SSL certificate. Here are two solutions, ordered by recommendation:

Option 1: Fix the SSL Certificates (Recommended, Secure) #

This resolves the issue long-term without compromising security:

• macOS: Open your terminal and run the certificate installation command for your Python version. For example, if you're using Python 3.10:

  /Applications/Python\ 3.10/Install\ Certificates.command
  

• Windows/Linux: Update the certifi package (which provides trusted SSL certificates) and use it in your code:
  First, run this in terminal:

  pip install --upgrade certifi
  

  Then modify your code to use the certifi certificate bundle:

  import json
  import certifi
  from urllib.request import urlopen
  
  # Use the raw GitHub URL here
  url = "https://github.com/UNAME/REPO/raw/master/test1.json"
  
  with urlopen(url, cafile=certifi.where()) as response:
      data = json.loads(response.read())
  print(data)
  

Option 2: Temporarily Disable SSL Verification (Not Recommended, For Testing Only) #

If you just need a quick test and understand the security risks (this makes your request vulnerable to man-in-the-middle attacks), you can create an SSL context that skips verification:

import json
import ssl
from urllib.request import urlopen

url = "https://github.com/UNAME/REPO/raw/master/test1.json"

# Create an SSL context that doesn't verify certificates
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

with urlopen(url, context=ctx) as response:
    data = json.loads(response.read())
print(data)

Final Notes #

Always go with Option 1 for production code. Fixing the SSL certificates is the secure, sustainable solution, and using the raw GitHub URL ensures you're actually loading JSON data instead of HTML.
