Writing and Running Your First Program
Create your first complete program, run it, and experience the satisfaction of working code.
Printing Text
Learn to display output using print() – your first tool for seeing what your code does.
Variables and Simple Values
Variables store data with meaningful names, making your code readable and reusable.
Common Data Types
Programs work with different kinds of data – text, numbers, and true/false values each behave differently.
Expressions and Operations
Expressions combine values and operators to calculate results – the building blocks of computation.
Getting User Input
Interactive programs ask users for information using input() – but remember, it always returns text.
Comments
Comments are notes for humans – they explain your thinking without affecting how the code runs.
Comparing Programming Languages
Different languages have different syntax, but the core concepts transfer – learning one helps you learn others.
Asking AI to Explain Code
AI can break down unfamiliar code and explain it clearly – a powerful skill for learning and debugging.
Reading Documentation
Documentation is the authoritative source of truth – learning to read it is a core developer skill.
Fixing Your First Error
Errors are normal – learning to read error messages and fix problems is a fundamental programming skill.
