Strings
Learn to work with text (strings) in Python.
5
Conditions
Learn to make decisions in your code using if/else statements.
6
Loops
Learn to repeat actions using loops.
7
Lists
Learn to store multiple items in lists.
8
Functions
Learn to create reusable blocks of code called functions.
9
Dictionaries
Learn to store data as key-value pairs using dictionaries.
10

Theory and exercises of these lessons are part of the VIP subscription.
15
While Loops Pro
Master the while loop: countdowns, break, continue and accumulators — the patterns behind real programs.
16
Nested Data
Real data is nested: lists inside lists, dictionaries inside lists. Learn to walk through it with double loops.
17
Exceptions
Programs meet bad data all the time. try/except lets your code survive errors instead of crashing.
18
Advanced Functions
Default values, any number of arguments, tiny lambda functions and sorting with a key — write functions like a professional.
19
Classes & OOP
Bundle data and behaviour together: your own types with attributes and methods — the heart of modern Python.
