How to check if a file is downloaded from a link?

Question

Python

The task is this.
There is a list of links.
When you click on some of them, the file starts to load.
But how can you filter out these links (that is, determine whether the file will be loaded or not)?
It is desirable to code in Python or a link where to read about it.

Among the HTTP response headers is Content-Type, which takes the value of one of the MIME types . The value text/htmlcorresponds to the HTML page and the value application/octet-streamcorresponds to the file being uploaded.

import requests

if __name__ == "__main__":
    r = requests.get('https://toster.ru/q/303883')
    r.raise_for_status()
    mime_type = r.headers['content-type']
    if mime_type == 'application/octet-stream':
        print('It is a binary file')
    if mime_type.startswith('text/'):
        print('It is a text')
