如果我想建立自己作为软件开发人员（Java，Python，C，C ++）的技能，那么必须使用什么类型的设置/工具？

I am a newbie in the software development field. I am hungry for more avenues through which I can develop, nurture, and mature in my development, scripting, and programming skills, more so outside of work time. I'd like to know what type of set-up (hardware and/or software) would be extremely beneficial or that others have found necessary for this endeavor. I am a newbie in the software development field
