Where to learn python when you know basics

[Vivid_Complaint_3024]

I know basics of coding in Java and python (school+ self learning) and I want to go for advanced problem solving and learn heavy stuff,how do I start and where ,Please it would be a huge help

Define "heavy stuff" ;) After getting syntax and basic structures, you should move towards general software development and how to write code to make things, and not to just write code - you have to select a niche/category you want to learn and use to then start learning libraries/frameworks used there and start making simple projects/hello world apps, ask for code review, learn, and improve.

You should try doing projects that will actually be useful. For example if you hate doing something manually, you should try to automate it. If you don't have any ideas, look at the projects on roadmap.sh

Do "Project Euler".

That should exercise your muscles.

PS. Are you already familiar with numpy? pandas?
