i think everyone who is new to coding needs a suggestion.
Pick something that interests you and that you know something about. Think of a need around that, a simple one, at first, and design a program to fit that need.
Like astronomy? Write a program to calculate luminosity or parallax.
Start with what you know, and let the learning begin as you go down that road. You’ll learn about programming and very likely learn more about your subject in the process.
