Assessment 03: Advanced

Goal

Combine class design, polymorphism, and generics-style type hints in one practical program.

Task

Write a program that:

1. Defines a polymorphic Shape hierarchy (Circle, Rectangle).
2. Stores shapes in a list of base-class references.
3. Calculates each shape area and total area.
4. Uses a generic helper to print any numeric list.
5. Prints min and max area values.

Learning Metadata

• Difficulty: Intermediate.
• Estimated Time: 45-60 minutes.
• Prerequisites: All 03-advanced modules, especially structs-and-classes, inheritance-and-polymorphism, and templates-basics.
• Learning Focus: Prove you can model abstractions, use reusable helpers, and summarize derived values correctly.

Quick Run

python main.py

Expected Output (shape)

Shape areas:
- Circle: ...
- Rectangle: ...
Total area: ...
Minimum area: ...
Maximum area: ...
Sample counts: [...]
Computed areas: [...]

Cross-Language Notes

• Compared with the C++ assessment, this version preserves the same abstraction goal with much lighter syntax and weaker compile-time enforcement.
• Relative to C#, Go, and TypeScript, the shared contract is carried more by design intent than by the type system.
• The comparison to watch is expressive modeling versus static guarantees.

What To Check

• abstraction or polymorphism is exercised through the language-appropriate shared interface
• derived numeric summaries come from computed values rather than hardcoded text
• the reusable helper works across more than one compatible input shape
