Welcome to Day 12 of The Complete Python Bootcamp.
In this session, you will be introduced to numbers in Python, one of the most essential parts of writing real programs.
You will explore the two main numerical data types in Python: integers, which represent whole numbers, and floats, which represent decimal numbers. Today, you will learn how to work with these data types, how to perform basic arithmetic operations and how Python handles numerical values in different situations.
By the end of this lesson, you will have a strong foundation for working with numbers in your programs and be ready to apply these skills to calculations, logic and real world problem solving.
✅ What You Will Learn in Day 12
• The difference between integers and floats in Python
• How to create, store and use numbers in your code
• How to perform basic arithmetic operations such as addition and division
• How Python interprets and processes numerical data
• How to mix numbers with variables for flexible calculations
• How numerical data types support future lessons such as comparisons, loops and functions
This session builds the groundwork for any program that needs to work with numbers.
🌍 Why Numbers Matter in Python
Understanding numbers helps you:
• Perform calculations and mathematical operations
• Build programs that track values, totals and user input
• Work with data analysis, automation and financial tasks
• Organise and process information in a structured way
• Prepare for more advanced concepts such as operators and expressions
Almost every program relies on numerical logic, which makes this lesson essential.
🎯 Who This Session Is Designed For
• Beginners learning Python step by step
• Students preparing for careers in development, data or analytics
• Learners who want clear explanations of numerical concepts
• Anyone who wants to understand how Python processes values
• Viewers who learn best through simple examples and guided practice
This lesson prepares you for more advanced arithmetic, expressions and decision making in upcoming sessions.
