Introduction to Python

Unit 1

Welcome to your first step in Python programming! In this unit, you will learn how to display messages using the print function and how to work with multiline strings to handle text that spans multiple lines. What is the print function, and how do you write a multiline string? Just start the lessons! :-) You will find out soon.

Unit 2

Let's not play around! In this unit, you will learn basic keywords in Python, and creating variables in Python. What is a variable? Just start the lessons! :-) You will find out soon.

Lesson 4

Variables for Strings

Unit 3

In this unit, you’ll dive into the world of math operators in Python. First, you’ll explore familiar math operators you already know, then discover some new ones that might surprise you, and finally, learn how Python decides the order to solve them all. Ready to crunch some numbers? Let’s get started!

Lesson 7

Math from Familiar Operators

Lesson 8

Unfamiliar Math Operators

Lesson 9

Operator Precedence

Unit 4

In this unit, you’ll explore the power of f-strings in Python. You’ll learn how to combine variables, perform calculations, and format outputs dynamically, making your code more efficient and readable. Ready to create some dynamic strings? Let’s get started!

Lesson 10

f-strings and the print function

Lesson 11

f-strings and variables

Lesson 12

f-strings and math operators

Unit 5

Get ready to make your programs interactive! In this unit, you’ll explore the input function, learn about data types, and discover how to convert input into strings or floats for even more functionality. Let’s get to it!

Lesson 13

Introduction to the input function

Lesson 14

Classifying Data Types

Lesson 15

User Input and Data Type Conversions

Unit 6

It's time to take your coding skills to the next level! In this unit, you'll learn how to make decisions in your programs using conditional logic. With tools like if, else, and elif, you'll be able to create programs that think and respond in exciting ways. Let's dive in and start building smarter code!

Lesson 16

Mastering Equality and Inequality Comparison Operators

Lesson 17

Boolean Data Types and Relational Operators

Lesson 20

Nested if and elif statements in Python

Lesson 21

Logical Operators

Lesson 22

Logical Operators vs. Nested if Statements

Unit 7

It's time to level up your coding skills! In this unit, you'll unlock the power of lists in Python, learning how to organize, access, and manipulate groups of data. From slicing and modifying to adding and removing elements, you'll discover how lists make your programs more dynamic and efficient. Let’s dive in and start mastering lists!

Lesson 23

Lists

Lesson 24

Adding and Changing Elements in a List

Lesson 25

Slices in Python Lists

Lesson 26

Deleting and Removing Elements in Python

Lesson 27

Mastering pop() in Python Lists

Lesson 28

Tuples

Unit 8

Loops help us repeat actions without writing the same code multiple times. In this unit, we will explore how for and while loops work with lists, tuples, strings, and the range() function, allowing us to process and control data.

Lesson 29

for loops - An Introduction

Lesson 30

The range function and for loops

Lesson 31

Looping through strings with for loops

Lesson 32

Mastering nested for loops in Python

Lesson 33

Introduction to while loops in Python

Lesson 34

Using while loops with conditionals

Unit 9

Dictionaries allow us to store and retrieve data using key-value pairs, making information more structured and accessible. In this unit, we will explore how to create, modify, and manage dictionaries, unlocking their full potential for organizing and processing data efficiently.

Lesson 35

Introduction to Dictionaries in Python

Lesson 36

The Versatility of Keys and Values in Dictionaries

Lesson 37

Looping Through Dictionaries

Lesson 38

Creating and Managing a List of Dictionaries

Lesson 39

Using len() - Lists in Dictionaries and Conditional Statements

Lesson 40

A Dictionary of Dictionaries

Unit 10

Functions in Python let us group a set of instructions under one name so we can reuse them whenever we need. Instead of repeating code, we can define a function once and call it as often as we want. In this unit, we’ll learn how to create and use functions to keep our code clean, organized, and easier to manage.

Lesson 41

Introducing Functions

Lesson 42

Functions - Positional Arguments and Parameters

Lesson 43

Functions - Keyword Arguments and Parameters

Lesson 44

Functions - Using Lists, Dictionaries, and Unknown Number of Arguments

Lesson 45

Functions - Passing Information Back

Lesson 46

Global vs. Local Variables

Unit 11

We will conclude our Introduction to Python Course with an introduction to classes. What are classes? What are objects, and how do classes relate to object-oriented programming? Our final 2 lessons will answer these questions. You have done well making it to this point, wonderful student! Let's make it to the finish line!
