programming "dictionary"?
As I'm learning in the classroom here and across Kraggle, I'm struggling to keep track of (and memorizing) the fundamentals (e.g. arithmetic, variables, functions, data types/integers/floats...ahhh!!). Similar to learning a new language, I need a dictionary (or simple resource for entry-level). I know I could google this but I also feel like someone here will have an excellent recommendation. Hoping for something free and simple...sorry if this has already been asked elsewhere.
