In python I can write code one line at a time and they are executed immediately. This means that I can write code to print the data if I want, or try different things etc without ever rerunning the program from scratch which can be very slow for training data.

Here, have a go at it with C++.

Being compiled doesn't mean anything, it is a matter of tooling.

Have fun :):

pretty cool. i wonder how well it works though

I use the evcxr repl all the time. It has some rough edges but it's incredible to finally have a rust repl that's functional. I had been using rusti on an ancient rustc. One thing I really like is that you can add a crate with one line (`:dep rand = "0.7"`).
