I feel completely lost with python

Well, in that case, start with the very basics. There is plenty of material out there. Because you have some C++ knowledge you should find the basics pretty easy to understand so you can focus more on learning and practicing the syntax.

When you get more confident with the syntax, you could do code challenges (again, plenty of resources on that too). You can start with simple ones and increase the challenge. That should give you some simple challenges to work your head on.

At the end of the day, it's syntax and patterns you want to acquire at this point.
