this course is only for the basics. anything more advanced, you'll have to look for info elsewhere. although sometimes Q&A can help.
you can modify modules written by Python on your own installation, but not on Sololearn.

thanks Ahri Fox, now I learned that Sololern gives only basic skill.

I think what you will learn in python course will be enough for creating a basic module in odoo, or modify existing one.
But if you want to become an odoo developer, in that case you need some knowledges in other domains, like : XML, Qweb (used to build reports), Odoo framework architecture, some functional concepts, common ERP concepts...
