Python-Snake-Game-Tutorial

Step-by-step Python game development project demonstrating how to build the classic Snake Game from scratch using incremental programming concepts.

This repository was created as part of hands-on learning sessions to teach core Python logic, game loops, event handling, collision detection, and basic GUI rendering through a practical and engaging use case.

---

🎯 Learning Objective

To help learners:

• Understand game loops and real-time input handling
• Work with keyboard events and movement logic
• Implement collision detection and scoring
• Manage state, velocity, and direction
• Build confidence in Python through a fun, visual project

---

🛠️ Tech Stack

• Python 3.x
• Standard Python libraries (graphics / GUI handling)
• File handling for score persistence

---

🧱 Architecture Overview

The project follows a progressive, tutorial-driven architecture:

• Initial GUI setup
• Keyboard input & event handling
• Snake movement & velocity
• Food generation
• Collision detection
• Score tracking & game-over logic
• Final polished gameplay

Each file represents a single development milestone, making the repo ideal for teaching, self-learning, and revision.
