What are the data types in Python?

Python training It supports several built-in data types, which are fundamental for working with data and performing various operations. Here are the most common data types in Python:

Numeric Types

int: Represents integer values, both positive and negative.pythonCopy codemy_int = 42

float: Represents floating-point (decimal) numbers.pythonCopy codemy_float = 3.14159

complex: Represents complex numbers with a real and imaginary part.pythonCopy codemy_complex = 2 + 3j

Text Type

str: Represents strings, which are sequences of characters enclosed in single or double quotes.pythonCopy codemy_string = "Hello, Python!"

Sequence Types

list: Represents ordered collections of items. Lists can contain elements of different data types and are mutable.pythonCopy codemy_list = [1, 2, 3, "Python", True]

tuple: Similar to lists but immutable, meaning their contents cannot be changed once created.pythonCopy codemy_tuple = (1, 2, 3, "Python", True)

range: Represents a sequence of numbers, commonly used for iterations.pythonCopy codemy_range = range(1, 6) # Represents [1, 2, 3, 4, 5]

Mapping Type

dict: Represents dictionaries, which are collections of key-value pairs. Dictionaries are unordered.pythonCopy codemy_dict = {"name": "Alice", "age": 30, "city": "New York"}

Set Types

set: Represents an unordered collection of unique elements.pythonCopy codemy_set = {1, 2, 3, 4, 5}

frozenset: Similar to sets but immutable, meaning their contents cannot be changed after creation.pythonCopy codemy_frozenset = frozenset({1, 2, 3})

Boolean Type

bool: Represents Boolean values, either True or False.pythonCopy codeis_valid = True

Binary Types

bytes: Represents a sequence of bytes and is immutable.pythonCopy codemy_bytes = b"Hello"

bytearray: Similar to bytes but mutable.pythonCopy codemy_bytearray = bytearray([72, 101, 108, 108, 111])

None Type

NoneType: Represents the absence of a value or a null value. It is often used to indicate that a variable does not point to any object.pythonCopy codemy_var = None
