Answer 1

I'd say
Python for beginners -> python core -> python intermediate
And you can later learn data structures or data science ..

Answer 2

Hi Abdul!
If you're a complete beginner, it's better to start with python for beginners then data structures, intermediate.
I can see that python core includes these three types of courses. So, you can try this if you have a pre knowledge about python and you're not interested to complete these things slowly.
You can go for python data science if you have any idea to learn about data science things.
