What Is Not a Data Type in Python?


Larry Thompson

Python is a versatile and powerful programming language known for its extensive support for data types. Data types in Python represent the various kinds of values that can be stored and manipulated.

They define the nature of data and the operations that can be performed on them. However, it’s important to note that not everything in Python can be considered a data type. In this article, we will explore what is not considered a data type in Python.

1. Variables

In Python, variables are used to store values.

They act as placeholders for data that can be changed or updated during program execution. While variables are crucial in working with data types, they are not considered a data type themselves.

2. Statements

Statements in Python are instructions or commands that perform specific actions when executed.

Examples of statements include assignment statements, conditional statements, loop statements, and function calls. Statements are used to manipulate data but are not considered a data type on their own.

3. Expressions

An expression is a combination of values, variables, operators, and function calls that evaluate to a single value.

Expressions are used to perform computations and return results based on the given inputs. While expressions involve working with data types, they themselves are not classified as data types.

4. Functions

Functions in Python are reusable blocks of code that perform specific tasks when called or invoked.

They encapsulate a set of instructions and can accept input arguments and return output values. While functions often work with different data types, they do not fall under the category of being a data type.

5. Modules

In Python, modules are files containing Python definitions and statements that can be imported into other programs as needed.

They provide an organized way to structure and reuse code. While modules can contain data types and operations related to them, they are not considered a data type themselves.

6. Classes

Classes in Python are blueprints for creating objects.

They define the structure and behavior of objects by encapsulating data attributes and methods that operate on those attributes. While classes can represent and work with various data types, they are not classified as a specific data type.


In Python, there are several elements that are crucial for working with data types but are not considered data types themselves. Variables, statements, expressions, functions, modules, and classes play essential roles in manipulating and organizing data in Python programs. Understanding the distinction between these elements and data types is important for writing effective code.

By familiarizing yourself with these concepts, you can enhance your programming skills and build more robust applications using Python’s diverse range of features.
