Python From Scratch Lesson 3 (Python Data Types, Numbers, and Casting)

Welcome to the third lesson of our Python From Scratch series! In this lesson, we will be exploring Python data types, Python numbers, and Python casting. As you may already know, data types are an essential concept in programming languages. In Python, data types allow us to classify and manipulate different kinds of information, such as numbers, strings, and booleans.

One of the most fundamental data types in Python is numbers. Python supports various number types, including integers, floats, and complex numbers. Understanding how to work with numbers in Python is crucial for any programmer, regardless of their experience level. In this lesson, we will delve into the basics of Python numbers and explore how to perform arithmetic operations with them.

Another important concept in Python is type conversion, or casting. Casting allows us to convert one data type to another, which is useful in many programming scenarios. In this lesson, we will explore how to perform casting operations in Python and learn some best practices for doing so.
