In Python, there are several built-in data types, each serving a specific purpose. The most commonly used data types in Python include:
Numeric Types:
Integer (int): Whole numbers without decimal points, such as 2 or -5.
Floating-point (float): Numbers with decimal points or in exponential form, like 3.14 or 1.2e5.
Complex (complex): Numbers represented as a combination of real and imaginary parts, such as 2 + 3j.
Boolean Type:
Boolean (bool): Represents the truth value, either True or False. This type is used for logical operations, conditional statements, and control flow.
Sequence Types:
String (str): Ordered collection of characters, enclosed in single quotes ('') or double quotes ("").
List (list): Ordered, mutable (changeable) collection of elements, represented within square brackets ([]).
Tuple (tuple): Ordered, immutable (unchangeable) collection of elements, represented within parentheses (()).
Mapping Type:
Dictionary (dict): An unordered collection of key-value pairs, represented within curly braces ({}). Keys are unique and used to access values.

Set Types:
Set (set): Unordered collection of unique elements, enclosed within curly braces ({}).
Frozen set (frozenset): An immutable set that cannot be modified after creation.

None Type:
None: Represents the absence of a value or a null value. It is commonly used to indicate a variable holds no value or to represent a default or initial state.
It's important to note that Python is a dynamically-typed language, meaning you don't need to explicitly define the data type of a variable. Python infers the data type based on the value assigned to the variable. Additionally, Python also provides the ability to create user-defined data types using classes and objects.
Understanding these data types is crucial for effective programming and data manipulation in Python.
