Python's built-in immutable and mutable types for variables.

 Python Built-in Variable Types (Data Types)

Python variables can hold values of various built-in data types. These are categorized broadly as follows:Numeric Types

• int: Integers (e.g., 42, -10).
• float: Floating-point numbers (e.g., 3.14, -2.5).
• complex: Complex numbers (e.g., 3 + 4j).

Sequence Types

• str: Strings (e.g., "hello", 'world').
• list: Mutable lists (e.g., [1, 2, 3]).
• tuple: Immutable tuples (e.g., (1, 2, 3)).

Mapping Type

• dict: Dictionaries (key-value pairs, e.g., {"key": "value"}).

Set Types

• set: Mutable unordered sets (e.g., {1, 2, 3}).
• frozenset: Immutable unordered sets (e.g., frozenset([1, 2, 3])).

Other Types

• bool: Boolean values (True or False).
• NoneType: The None object (represents no value).

These types are determined dynamically (Python is dynamically typed), and you can check a variable's type using the type() function, e.g., type(42) returns <class 'int'>. For more advanced or user-defined types, Python supports classes and objects via OOP.
