What should I learn next?

So basically I’ve just finished the Python course and I want to continue learning until I can build some small stuff on my own or do some easy freelancing jobs, but I just can’t seem to find any free courses that will let me reach that state… What would you guys suggest?

Also what mostly interests me is IOT, but I’m not 100% sure what do I want to do yet…

more python? Other resources like sololearn, udemy and udacity. And trying to build stuff. maybe a simple web scraper with beautifulsoup4?
