What Is Built-in Data Type in Python?
Python is a versatile programming language that offers a wide range of built-in data types. These data types help in storing and manipulating different kinds of values within a program. Understanding the various built-in data types in Python is essential for anyone looking to become proficient in this language.
Numeric Data Types
Python provides several numeric data types, including:
- int: Represents integer values, such as 5 or -10.
- float: Represents floating-point numbers, such as 3.14 or -2.5.
- complex: Represents complex numbers with real and imaginary parts, such as 2+3j.
Sequence Data Types
In Python, sequence data types allow you to work with collections of items. The main sequence data types are:
- str: Represents a sequence of characters enclosed in single or double quotes, like “Hello” or ‘World’.
- list: Represents an ordered collection of items enclosed in square brackets, such as [1, 2, 3] or [‘apple’, ‘banana’, ‘cherry’].
- tuple: Similar to lists but immutable (cannot be modified), enclosed in parentheses, like (1, 2, 3) or (‘red’, ‘green’, ‘blue’).
Mappings and Sets
In addition to sequences, Python provides two other built-in data types:
- dict: Represents key-value pairs enclosed in curly braces, such as {‘name’: ‘John’, ‘age’: 25}.
- set: Represents an unordered collection of unique elements enclosed in curly braces, like {1, 2, 3} or {‘apple’, ‘banana’, ‘cherry’}.
Boolean Data Type
The boolean data type is a fundamental type in Python. It represents the truth values True and False. Boolean values are often used in conditional statements and logical operations to control the flow of a program.
None Data Type
The None data type is used to represent the absence of a value. It is often used as a placeholder when a variable needs to be defined but does not have a specific value yet.
Conclusion
In this tutorial, we explored the various built-in data types available in Python. From numeric data types like int and float to sequence types such as str and list, each data type serves its purpose in Python programming. Understanding these data types is crucial for writing efficient and effective code.
Now that you have a good grasp of Python’s built-in data types, you can start using them to create powerful and dynamic programs!

What Is Mean of Built-in Data Type in Python? In Python, data is stored in variables. Each variable has a data type that determines the kind of value it can hold.
In Python programming, data types are used to specify the type of data that a variable can hold. Different data types allow us to store and manipulate different kinds of data in our programs. Why are Data Types Important?
Python is a versatile programming language that allows developers to work with different types of data. Understanding data types is crucial in Python as it determines the kind of operations that can be performed on a particular variable. In this tutorial, we will explore the concept of data types in Python and provide examples to illustrate their usage.
A data type is a classification of the type of data that a variable or object can hold in a programming language. In Python, data types are used to define the kind of value that a variable can store. It helps Python to understand what type of operations can be performed on a given set of values.
In Python, data types are classified into two categories: mutable and immutable. In this article, we will focus on understanding what immutable data types are and how they differ from mutable data types. What Are Immutable Data Types?
In Python, the real data type refers to numbers that contain decimal points. These numbers are commonly known as floating-point numbers or floats. In this article, we will explore the real data type in Python and understand its characteristics and usage.
A user-defined data type, also known as a custom or composite data type, is a data type that is created by the user in Python. It allows programmers to define their own data structures, which can be composed of different built-in or other user-defined data types. Creating a User-Defined Data Type
In Python, we can create a user-defined data type using classes.
What Is Immutable Data Type in Python? Give Example. Python is known for its flexibility and extensive range of data types.
The object data type in Python is a versatile and powerful feature that allows you to create and manipulate any type of data. In this article, we will explore the concept of object data type and how it can be used in Python programming. Let’s dive in!
Can You Define Data Type in Python? In Python, a data type defines the type of data that a variable can hold. Python is a dynamically typed language, which means that you do not need to explicitly declare the data type of a variable.
