Lesson 12. Parameterized Functions and Dynamic Scripts

• Brief recap of basic functions and a quiz on function execution order

• Concept breakdown: passing arguments and parameters into Python functions

• Teacher modelling: creating a build_wall(length, height) function in Python

• Guided task: modifying functions to accept different material block types

• Student practice: write a flexible script that builds custom sized houses

• Discussion on abstraction: generalizing code to handle variable inputs

• Formative check: predicting function output based on passed arguments

• Independent task: design a versatile bridge-builder function with parameters

• Debugging challenge: handling invalid parameter values gracefully in Python

• Peer testing: calling classmates’ functions using custom argument values

• Evaluation of parameterized code versus hardcoded script alternatives

• Summary of parameters and introduction to event-driven programming
