How to make your own stuff

How do I make my own code projects? Like, I want to use code academy’s really helpful coding interface, but I want to make my own stuff. How do I do this?

That question is very broad, and does not come with an all inclusive answer.

If you want ruby, you will need to install ruby
if you want python, you will need to install python
and so forth.

you will need a text-editor or an IDE, but this is also language specific. I mean, you might want Spyder (python IDE) or a general text-editor like atom.
