Python Geek is a programming competition that tests participants' conceptual understanding of Python. It has three phases - a written test with MCQ and short answer questions, a debugging round where participants fix code bugs, and a coding round where they implement solutions. The top scoring individuals in each round advance. Registration is online but on-site registration is also accepted up until 30 minutes before the start. The competition aims to evaluate Python skills like problem-solving, logic, and efficiency.
