I started learning python on a site called codefinity, where i improved fast and dived into topics like oop or nodes after a few months. then there were no more c++ or python courses, so i stopped learning there, while trying to find other websites or books where i could keep improving, but i never found anything like that. This was more than a year ago, and at some point i stopped searching for new possibilities, bc they never suited me. I'm still in school, so i can't just study at a university or smt like that, still i find coding very interesting, so i wanted to ask, if one of you knew a site or book or anything like that, where i can refresh the knowledge i gained so far in a short period of time (forgot many synthaxes and most aspects of oop), and then keep improving until one could call me advanced. Idc if it costs money btw.

Thanks a lot!
