Answer 1

Let's take a closer look at your error. It is located here - response = requests.get(url)
An error of type ConnectionError tells us that the requests.get function could not wait for a response from the resource (URL) passed to it. How did it happen?
You give the url parameter f'http://{random.choice(n)}', and random.choice(n) should choose a suitable host from n, but returns rian_ru?
It is unlikely that you will be able to open the site rian_ru right?
In addition, you should definitely listen to THIS song and fix all the styling errors in your code, which are terrifying, sorry.
