Since you are trying to pass an URL as parameter, you rather want to use a query parameter (eg try1?url=ADDRESS) or send the URL via a POST Request.

Using a Website URL and its' path within a path parameter is a pretty bad idea.

You can use a query parameter like this in a request:

from flask import request
url = request.args.get('url')
