How Python and Turtle Made Programming Click
As a software developer and dad to two curious boys, I live in one world of code and another of LEGOs. Watching my kids snap together simple blocks to build increasingly complex creations, I can't help but see the similarity to how we build software from just a few basic "blocks" of code.
The Final Project
In the previous unit, we covered game loops, state management, and collision detection. Now let's put it all together and build Snake.
Building Interactive Games with Turtle
In the previous unit, we covered project management with Poetry. Now we're shifting back to Turtle graphics to explore game development concepts that we'll use in the final unit to build Snake.
Finding Bugs and Handling Exceptions
In the previous unit, we worked with JSON data. Now let's learn how to find and fix bugs, and how to handle errors gracefully when they occur.
Reading and Writing Structured Data
In the previous unit, we learned to fetch data from APIs. Now let's understand JSON, the format that powers most of those API responses.
Built-in Modules You Already Have
In the previous unit, we learned how to create packages and install external libraries. Now let's explore modules that come built into Python, ready to use without installing anything.
Organizing Modules and Using External Code
In the previous unit, we learned to create modules. Now let's organize multiple modules into packages and explore how to use libraries from the Python community.
Organizing Code into Reusable Files
In the previous unit, we explored recursion. Now let's learn how to organize code into modules, separate files that you can import and reuse across projects.
Functions That Call Themselves
In the previous unit, we finished our exploration of OOP. Now let's look at recursion, a technique where a function calls itself to solve a problem.
Controlling Access and Creating Flexible Interfaces
In the previous unit, we explored inheritance. Now let's look at two more OOP concepts: encapsulation and polymorphism. Encapsulation controls access to an object's data. Polymorphism lets different classes share a common interface.
