If I'm looking for problems I always like to try Advent of Code problems, it's a good chance to learn basic io, sample the standard library, and learn how to idiomatically handle common problems. But before that I prefer to get a book and work my way through all the examples, otherwise I'm just making up what "idiomatic" means.
