Variables, text, collections, loops, and the decisions your code makes.
- 01Variables and Data Types
Variables and data types are the fundamental building blocks of any Python program.
- 02Strings and Text
At its heart, this concept is about how a programming language represents and manipulates text.
- 03Lists and Collections
Lists and collections are about grouping related pieces of data so your program can work with them as a unit.

At its heart, a loop is a way to tell the computer to repeat a set of instructions without you having to write them over and over.
- 05Conditionals and Decisions
Conditionals are how your program makes choices.
