How to make a smart chat bot in Python?

Question

Chats

I am making a voice assistant .

So far, he can open habr q&a, open discord, and so on.

And I want to make sure that if none of the conditions is met, the assistant answers with the help of artificial intelligence.

In the last question , I asked how to connect dialogflow to a Python script. Nobody helped me. Maybe you can do it differently.
