Summary  
This chapter covers decomposition: breaking complex tasks into smaller, reusable functions and composing them hierarchically to simplify and organize code.  

General domain of usage  
Game development

In the context of the Ninja Game, decomposition allows to create functions that can be reused and combined to perform more complex tasks. By calling functions within other functions, we can build a hierarchy of operations that simplifies the overall task.

Look at an example to understand how decomposition works:

In the example above, there is a function `ninja_controller` that calls another function `loot_tunnel` three times. The `loot_tunnel` function itself performs a series of actions to collect sushi from a tunnel and then calls `move_to_next_tunnel` to position the ninja for the next tunnel. This layered approach makes the code easier to understand and modify.

Now, it's your turn to practice decomposition by completing the following task.

Welcome to the Python Ninja Course! This engaging and interactive course is designed to introduce you to the fundamentals of Python programming through a fun and educational game. You'll guide a ninja through various challenges, using Python to control movements and interact with objects like sushi. Starting with the basics, you'll learn how to navigate the map, pick up and place sushi, and gradually progress to more complex programming concepts such as functions, loops, and conditional statements. Each chapter offers hands-on practice to reinforce your learning, culminating in exciting challenges that test your skills.

Explore the foundational features of Python through the engaging Ninja Game. You'll learn how to use Python commands to control your ninja's movements and interactions on the grid, mastering essential functions like moving, picking up, and placing sushi. Through hands-on practice, you'll apply these skills to solve fun challenges, reinforcing your understanding of Python's basic capabilities.

Take your ninja skills to the next level with more complex movement and control logic. In this section, you’ll learn how to combine multiple commands, sequence actions efficiently, and plan precise routes across the grid. You’ll tackle new challenges that involve moving, picking up, and placing sushi strategically, often requiring creative problem-solving and multi-step thinking.

Delve into the powerful Python feature of creating and utilizing functions to streamline your code. You'll learn how to write functions to perform specific tasks, enhancing code reusability and clarity. By practicing decomposition, you'll break down complex problems into simpler functions, mastering the art of organized and efficient coding.

Explore the essential Python feature of loops, which allows you to execute repetitive tasks efficiently. You'll learn to implement both for loops and while loops, gaining the ability to automate actions and iterate over sequences. By mastering nested loops, you'll tackle more complex scenarios, enhancing your ability to write concise and powerful code.

Learn how to use Python's conditional logic to make decisions within your code. You'll explore how if-else statements allow your ninja to respond dynamically to different scenarios, enabling more intelligent and adaptable behavior. Through practical exercises, you'll apply these concepts to solve challenges, enhancing your ability to write responsive and decision-driven code.

Apply your Python skills to tackle a series of engaging and complex problems. These challenges will test your understanding of loops, functions, and conditional logic as you guide your ninja to align columns, build letters, and traverse intricate patterns. By solving these puzzles, you'll refine your coding abilities and gain confidence in applying Python to creative and real-world scenarios.

Learn how lists enable you to store multiple items, perform operations, and manage data efficiently. Through practical exercises, you'll apply these concepts to solve challenges, improving your ability to write organized and dynamic code for handling collections of information.
