Learn Python Classes and Objects

An incremental LearnPack to practice how to model real-world data using Python classes.

Project Goal

Build practical OOP skills through 12 short exercises that increase in complexity.

By the end of this LearnPack, students should be able to:

• Create classes and instantiate objects
• Define attributes and methods
• Validate and normalize object state
• Work with composition and collections of objects
• Use encapsulation and properties
• Apply inheritance to reuse behavior

Curriculum Outline

• 00-Welcome: Course intro and workflow
• 01-03: Class basics, constructors, and methods
• 04-06: Validation, defaults, and object representation
• 07-09: Composition and lists of objects
• 10-12: Properties, encapsulation, and inheritance

Exercise Structure

Each folder inside exercises/ should contain exactly:

1. README.es.md with one clear learning objective
2. app.py as the student template
3. test.py with isolated pytest tests

Local Run

After container setup:

1. Start LearnPack:

learnpack start

2. Open the exercise UI in the forwarded browser tab.

Notes

• This repository is designed for GitHub Codespaces and LearnPack.
• Keep exercises focused on one responsibility per step.
