Course 3

Beginner Python

Write and debug Python programs with variables, input, decisions, loops, functions, validation, and clear output. The course combines structured lessons, guided browser concept simulations, and learner-created project files made with freely installable or open tools described in the course instructions. This guided page does not execute code, train models, run databases, create repositories, access hardware, or provide hosted infrastructure.

Free completion promise: The always-free pathway combines guided browser concept simulations with learner-created Python files made in a freely installable or open tool. The C4T page does not execute Python.

C4T Python Concept Simulator

Free

A free browser concept simulator with adjustable values, a prediction prompt, deterministic feedback, and a short explanatory trace. This guided page does not execute code, train models, run databases, create repositories, access hardware, or provide hosted infrastructure. Use keyboard controls and the text trace or written alternative when a visual or pointer interaction is not suitable.

Open the concept simulator and read its scenario, assumptions, and limitations.

Assignments & capstone

Free tools accepted

Calculator and quiz pair

Build a validated calculator and a scored quiz, each organized around small functions and readable output.

The always-free pathway combines guided browser concept simulations with learner-created Python files made in a freely installable or open tool. The C4T page does not execute Python. Submit a project file, text trace, screenshots with descriptions, or equivalent simulator evidence.

Loop-driven word game

Create a word or number game with repeated turns, validation, a stopping condition, and useful error messages.

Final assessment

Complete text-based Python application

Build a calculator, quiz, game, or text adventure that uses input, output, variables, conditions, loops, functions, validation, and clear error handling. Deliverables: Runnable Python source, Documented user flow, Normal and edge-case tests, Helpful validation and errors, and Reflection on one debugging decision.
