Different Data Types in Python.
In Python, data types are classifications that determine the type of data that a variable can hold. Python has several built-in data types to handle different kinds of data. Here are some of the main data types in Python:
Numeric Types:
int
: Integer type, e.g., 1, 100, -25.float
: Floating-point type, e.g., 3.14, -2.718.
Sequence Types:
str
: String type, e.g., "Hello, World!", 'Python'.list
: Ordered collection of elements, e.g., [1, 2, 3], ['apple', 'banana'].tuple
: Immutable ordered collection, e.g., (1, 2, 3), ('a', 'b', 'c').
Mapping Type:
dict
: A dictionary that stores key-value pairs, e.g., {'name': 'John', 'age': 30}.
Set Types:
set
: An unordered collection of unique elements, e.g., {1, 2, 3}, {'apple', 'orange'}.frozenset
: An immutable version of set.
Boolean Type:
bool
: Represents boolean values, either True or False.
None Type:
None
: Represents the absence of a value or null.
Sequence Iterator Types:
range
: Represents a range of numbers, e.g., range(5) generates 0 to 4.
Binary Types:
bytes
: Immutable sequence of bytes, e.g., b'Hello'.bytearray
: Mutable sequence of bytes.
Collection Types:
list
,tuple
,set
,frozenset
, anddict
are collectively referred to as collection types.
Custom or User-defined Types:
- Python also allows defining custom classes to create user-defined types.
