##1. Level description Level 1 Beginner: Beginner means someone who has just gone through an introductory Python course. He/She can solve some problems with 1 or 2 Python classes or functions. Normally, the answers could directly be found in the textbooks.
Level 2 Intermediate: Intermediate means someone who has just learned Python, but already has a relatively strong programming background from before. He/She should be able to solve problems which may involve 3 or 3 Python classes or functions. The answers cannot be directly be found in the textbooks.
