Interface Design: Designing and improving function with turtle graphics
4.1 The turtle module
Introduction to the turtle module.
Creating Turtle objects
Moving the turtle and drawing.
4.2 Simple repetition
Drawing sqares with repeated commands.
Using loops to simplify code.
4.3 Exercises
Practice drawing more complex figures.
4.4 Encapsulation
Wrapping code into functions.
Benefits of modular code.
4.5 Generalization
Adding parameters to functions.
Making functions flexible (Ex: varying side lengths and number of sides)
4.6 Interface Design
Designing clean, simple function interfaces.
Keeping user interaction straightforward.
4.7 Refactoring
Improving code by identifying repetition.
Creating general helper functions (ex: polyline)
4.8 A development plan
Step-by-step: build first, then encapsulate, generalize, and refactor.
4.9 docstring
Documenting functions properly.
Using triple quotes for function descriptions.
4.10 Debugging
Preconditions (what must be true before function starts).
Postconditions (what should be true after function runs).
Debugging based on clear contracts.
