Which Python tutorial is can help to learn Python from elementary to advanced level in simple and easy steps?
This one is good to get started: https://codecasts.teachable.com/p/python-crash-course
The official docs were great when I learnt Python more than a decade ago. They still are. After that, maybe pick up Fluent Python to understand the internals in detail.
