getcomposer, laravel and  python 3.6.1

That's what I need. But I did not know how to make it.
I installed python but it did not work.
I get it as getcomposer xampp but I do not understand it with cwp.

I collapsed 5-6 vps. ^^

Composer; https://getcomposer.org/   
python ; link?   CWP  2.6.x install...:/
laravel;  https://laravel.com/docs/5.5/installation
