What this course promises

For
Motivated beginners who want to write their first Python programs.
Prerequisites
No programming experience required · Basic keyboard and file skills are helpful
Expected effort
About 3 to 5 hours plus time to build the final game
Tools and materials
A computer with Python 3 and Turtle · A text editor or Python learning environment
What you will be able to do
Build and explain a working Turtle game that combines the course concepts.

By the end, you should be able to

  • Use variables, conditions, loops, functions and lists in small Python programs
  • Predict program behaviour and debug common mistakes
  • Break a program into reusable parts
  • Design, build, test and explain a small Turtle game

  1. № 01 · Getting started

    Cheat-sheet for this module
    Checkpoint: show what you can do

    You should be able to

    • • Trace variables and control flow
    • • Use loops to create a visual pattern

    Predict a Turtle pattern before running it. Then run it, compare the result and change one variable to create a deliberate variation.

    Evidence: Your prediction, the result and one explained revision.

    Need a hint?

    Trace one loop iteration at a time and keep angle and distance separate.

  2. № 02 · Reusable code

    Cheat-sheet for this module
    Checkpoint: show what you can do

    You should be able to

    • • Turn repeated code into a function
    • • Choose useful parameters and return values

    Take one repeated drawing or calculation and refactor it into a named function. Test it with two different inputs.

    Evidence: Working code plus one sentence explaining the function boundary.

  3. № 03 · From code to ideas

    Cheat-sheet for this module
    Checkpoint: show what you can do

    You should be able to

    • • Connect code to events, data and simple models
    • • Explain limits rather than treating output as magic

    Choose the cipher or event-driven example. Predict one output, test it, find one limitation and improve the program.

    Evidence: A before-and-after example with an explanation of the change.

  4. № 04 · Build it

    Cheat-sheet for this module
    Checkpoint: show what you can do

    You should be able to

    • • Plan, build, test and explain a small game
    • • Revise a project after observing a failure

    Build the capstone game, ask someone else to try it, record one problem they encounter and revise the game.

    Evidence: A working game, test note and explained revision.

The story

Python, algorithms and an introduction to artificial intelligence.

An introductory Python programming program. From drawing with Turtle through variables, conditionals, loops and functions, students built the foundations of algorithmic thinking step by step.

Through guest workshops with data scientists and researchers, the program connected Python fundamentals to real examples from machine learning and data science.
