How to successfully download range of bytes instead of complete file using python?

I am trying to download only range of bytes of a file and I am trying the following process:

r = requests.get('https://stackoverflow.com', headers={'Range':'bytes=0-999'})

But it give status code 200 as opposed to 206 and I am getting the entire file.

I tried following this Python: How to download file using range of bytes? but it also gave me status code 200. What is the reason and how do I download files partially using python?

Headers for stackoverflow:

This requires server-side support. Probably the server does not support it.

To find out, make a HEAD request and see if the response has Accept-Ranges.
