About

Coding School

Features
Read full description

Coding School helps beginners build a practical foundation in programming through focused lessons, checkpoints, exercises, and small projects. Start with Basic Swift or Basic Python and learn one topic at a time. Each lesson breaks concepts into short sections, shows readable code examples, and checks understanding before moving forward. After the lesson, practice with multiple choice, multi-select, fill-in-the-blank, code-entry, and project-style exercises. What you can learn: - Swift variables, constants, types, operators, conditionals, loops, collections, functions, optionals, structs, enums, closures, protocols, extensions, error handling, and SwiftUI basics. - Python variables, basic types, conditionals, loops, lists, dictionaries, functions, classes, modules, imports, files, and exceptions. - Final review tests and project practice to reinforce what you have learned. Features: - Beginner-friendly explanations with code examples. - Checkpoints inside lessons to confirm understanding. - Interactive exercises with hints and explanations. - Progress tracking for completed subtopics and lessons. - Free access to the first lessons, with a one-time purchase to unlock all lessons. Coding Tutorial is designed for learners who want a clear, structured path through programming basics without account setup or distractions.
