This is my first coding attempt and my first day on the forum, so I have a lot to learn
Welcome aboard! 
When it comes to popping your code into posts on the forum, its typically better to copy/paste the code, and save screenshots for errors in the editor(s). The forum does quite well at determining which bits of your post is code, but, to format it nicely, if you add ``` before the code block and after it, it will look awesome. It’s also really useful for those that help you as they can just copy/paste a chunk of it back to you in a reply
Hope this helps and again, welcome to the community.
