Answer 1

Based on your codes, you are beginner.
Study the SoloLearn extra courses about algorithms, data structures, design patterns. Try to implement some of them on your own too, like search algorithms.
Read the python documentation of standard modules, it has lots of examples too. Standard libraries like itertools, functools, collections, urllib, sys, os - these are very useful to know about.
If you are interested in machine learning, also learn the numpy library.

Try to do the more difficult challenges on SL, analyse other Pythonist's codes, and try to do a bigger project on your own to solve a complicated problem. Maybe something you can also use in real life.

Answer 2

Try working with functional programming, OOP, solve problems at codewars. Just keep practicing, if you think that you know whole Python, try learning some libraries

Answer 3

I think intermediate, rather that beginner, but there is no limit in learning
