Welcome back to your Python learning journey! 🚀 In this chapter, we will explore some fundamental building blocks of Python programming: variables and data types. Let’s dive into the exciting world of data management in Python and work on a delightful project together! In this chapter, we will delve into variables, which allow us to store and manipulate data, and explore different data types available in Python.

We’ll utilize these concepts in a project that creates a personalized greeting card! In this lesson, we will explore variables, understand different data types, and learn about type conversion in Python. Variables act as identifiers for data in our code, enabling us to label, store, and manipulate data within our programs. In Python, variables are dynamically typed and do not need to be declared before assignment. Variables in Python are initiated the moment you first assign a value to them. Unlike some other languages, you don’t need to declare their type, and you can even alter the type after they have been set.

Chapter: Understanding data types in Python. Just getting started with Python? Python data types explained is one of the first things you’ll want to wrap your head around. Understanding how data works in Python gives you the building blocks to write code that actually does something. This beginner-friendly guide walks through the main data types in Python, with simple examples you can try right away. You’ll get the hang of how Python handles different types of numbers, how to play with text using strings, and how to check or switch data types when needed.

Every section includes hands-on code samples so you can see it all in action. <img decoding="async" src="https://openpython.org/wp-content/uploads/2025/08/uploaded-image-1.jpeg" alt="Python data types explained with examples"> Python data types explained really just means knowing the basic types of data you can use in the language. These are like the ingredients in a recipe. Whether you’re dealing with numbers, words, files, or logic, Python gives you a type for it. Describe how Python understands how to process a piece of data.

Perform simple operations involving the formatting of strings. How Python performs operations depends on the data type. In this section, we will do the following: In the previous section, we created a variable containing the URL of the API we will be working with for the workshop. It was mentioned that you need to encapsulate the URL within quotes. In this section, we will talk about data types and how Python makes sense of them.

Data types specify the different sizes and values that can be stored in the variable. For example, Python stores numbers, strings, and a list of values using different data types. Learn different types of Python data types along with their respective in-built functions and methods.

This repo is about learning python from basic to advanced level. Imagine you're organizing your kitchen. You don't throw flour, sugar, and salt into one jar. Instead, you label each jar clearly: "flour," "sugar," "salt." Why? Because each ingredient is different. They look different, they taste different, and they need different storage conditions.

Python does something similar with data. When you write a program, you work with many kinds of information: ages (numbers), names (text), whether something is true or false (yes/no decisions), and groups of items (lists of scores). Python needs to keep these straight. Otherwise, something strange happens. Why does 5 + "hello" fail, but 5 + 5 and "hello" + "world" work? Because types determine what operations are valid.

This lesson explains the "why" before showing you the syntax. A data type is Python's classification system for different kinds of data. In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on... On literal data, it tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support basic data types of integer numbers (of varying sizes), floating-point numbers (which approximate real numbers), characters and Booleans.[2][3] A data type may be specified for many reasons: similarity, convenience, or to focus the attention.

It is frequently a matter of good organization that aids the understanding of complex definitions. Almost all programming languages explicitly include the notion of data type, though the possible data types are often restricted by considerations of simplicity, computability, or regularity. An explicit data type declaration typically allows the compiler to choose an efficient machine representation, but the conceptual organization offered by data types should not be discounted.[4] Different languages may use different data types or similar types with different semantics. For example, in the Python programming language, int represents an arbitrary-precision integer which has the traditional numeric operations such as addition, subtraction, and multiplication. However, in the Java programming language, the type int represents the set of 32-bit integers ranging in value from −2,147,483,648 to 2,147,483,647, with arithmetic operations that wrap on overflow.

In Rust this 32-bit integer type is denoted i32 and panics on overflow in debug mode.[5] Most programming languages also allow the programmer to define additional data types, usually by combining multiple elements of other types and defining the valid operations of the new data type. For example, a programmer might create a new data type named "complex number" that would include real and imaginary parts, or a color data type represented by three bytes denoting the amounts each of... Data types are used within type systems, which offer various ways of defining, implementing, and using them. In a type system, a data type represents a constraint placed upon the interpretation of data, describing representation, interpretation and structure of values or objects stored in computer memory. The type system uses data type information to check correctness of computer programs that access or manipulate the data.

A compiler may use the static type of a value to optimize the storage it needs and the choice of algorithms for operations on the value. In many C compilers the float data type, for example, is represented in 32 bits, in accord with the IEEE specification for single-precision floating point numbers. They will thus use floating-point-specific microprocessor operations on those values (floating-point addition, multiplication, etc.).
