Hey, how can you get the stars in this game to people, and how can you get the people then to get artifictial intelligence so you can write things that you ask them?


What game? You have not provided enough information for anyone to give you advice.

I’ve edited your post for readability. When you enter a code block into the forum, remember to precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

As you are already aware, we are primarily here to help people with their Free Code Camp progress which is focused on web development with html, css and JavaScript. Since the questions you have pertain to Python, you might have to wait a bit for a response to your topic.


Okay, I don’t understand how to make it easier to read.
