🚀 Module 1: Getting Started

Set up Python and make your programs talk and listen.

 LESSON 1 

Introduction to Python

What Python is, its history, features, how it runs your code and where it is used.

History · Features · Interpreter · Zen of Python

 LESSON 2 

Installing Python

Step-by-step setup on Windows, Ubuntu and macOS, pip, virtual environments and editors.

Windows · Ubuntu · macOS · pip · venv

 LESSON 3 

The print() Function

Display output like a pro: sep, end, escape sequences and f-string formatting.

sep · end · \n · f-strings · alignment

 LESSON 4 

The input() Function

Take user input, convert types, read multiple values and handle wrong input safely.

int() · float() · split() · map() · try/except

🧱 Module 2: Core Building Blocks

Store data, make decisions, repeat tasks and write reusable code.

 LESSON 5 

Python Data Types

int, float, str, bool, list, tuple, set, dict, None — and mutable vs immutable.

Numbers · Strings · Collections · Type casting

 LESSON 6 

Python Lists

Indexing, slicing, adding and removing items, sorting and list comprehensions.

append · pop · sort · slicing · comprehension

 LESSON 7 

if, elif, else

Make decisions with conditions, logical operators, ternary operator and match-case.

Conditions · Nested if · Ternary · match-case

 LESSON 8 

for and while Loops

Repeat tasks with range(), break, continue, loop-else, nested loops and patterns.

range() · break · continue · Patterns

 LESSON 9 

Python Functions

Write reusable code: parameters, return, *args, **kwargs, scope, lambda and recursion.

def · return · *args · lambda · recursion

 

🏛️ Module 3: Object-Oriented Programming

Think like a software engineer and model the real world with classes.

 LESSON 10 

Programming Paradigms

Procedural vs object-oriented vs functional programming — one problem, three styles.

Procedural · OOP · Functional · map/filter

 LESSON 11 

Classes and Objects

Blueprints and instances, __init__, self, attributes, methods and dunder methods.

class · __init__ · self · @classmethod

 LESSON 12 

random.seed()

How random numbers work and why the seed makes results reproducible.

random · seed · ML reproducibility · secrets

 LESSON 13 

Encapsulation

Protect your data with private members, getters, setters and @property.

_protected · __private · @property

 LESSON 14 

Polymorphism

One interface, many forms: overloading, overriding, operator overloading, duck typing.

Overriding · __add__ · Duck typing

 LESSON 15 

Inheritance

Reuse code with single, multiple, multilevel, hierarchical and hybrid inheritance and MRO.

super() · MRO · Diamond problem
