I don't have suggestions, though I could look for some later. Maybe someone with personal experience with them can chime in.
Basically, search for "free online beginner coding classes". Avoid anything paid for now. There are a lot of scams, but you really don't need to pay for classes to learn.
Failing that, search YouTube for tutorials, though it helps if you know what you want to do. Start with something simple. For example analyzing a data set, make a simple game, something like that.
