There are a few things that hold programmers back when learning a language - those are: Not quite knowing how to use external libraries, not knowing how to debug (except by print statements) and being unaware of language idioms and no nos.
So, do you want to be able to read and understand Python code better? Do you want to be able to debug efficiently? Do you want to avoid mistakes that interviewers notice and write impressive code instead? I will review your code and point those out, show you how to debug and how to figure out how to use a library with shaky documentation.
