Data types specify the type of data that a variable can hold. Python has various built-in data types that allow you to work with different kinds of data effectively.<\/p>\n\n\n\n

Common Data Types in Python<\/strong><\/h2>\n\n\n\n
    \n
  1. Numeric Types<\/strong>: Integers, Floating-Point Numbers, and Complex Numbers<\/li>\n\n\n\n
  2. Sequence Types<\/strong>: Strings, Lists, and Tuples<\/li>\n\n\n\n
  3. Mapping Type<\/strong>: Dictionaries<\/li>\n\n\n\n
  4. Set Types<\/strong>: Sets and Frozensets<\/li>\n\n\n\n
  5. Boolean Type<\/strong>: Booleans<\/li>\n\n\n\n
  6. Binary Types<\/strong>: Bytes, Byte Arrays, and Memory Views<\/li>\n<\/ol>\n\n\n\n

    <\/p>\n\n\n\n

    Numeric Types<\/strong><\/h2>\n\n\n\n

    1. Integers<\/strong><\/p>\n\n\n\n

    Integers are whole numbers, both positive and negative, without a fractional part.<\/p>\n\n\n\n

    x = 10\ny = -5<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    2. Floating-Point Numbers<\/strong><\/p>\n\n\n\n
    Floating-point numbers are real numbers with a decimal point.<\/p>\n\n\n\n
    a = 3.14\nb = -2.5<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    3. Complex Numbers<\/strong><\/p>\n\n\n\n
    Complex numbers are written with a real part and an imaginary part.<\/p>\n\n\n\n
    c = 2 + 3j\nd = complex(1, -1)<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Sequence Types<\/strong><\/h2>\n\n\n\n
    1. Strings<\/strong><\/p>\n\n\n\n
    Strings are sequences of characters enclosed in single or double quotes.<\/p>\n\n\n\n
    text = "Hello, World!"<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    2. Lists<\/strong><\/p>\n\n\n\n
    Lists are ordered, mutable collections of items.<\/p>\n\n\n\n
    fruits = ["apple", "banana", "cherry"]<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    3. Tuples<\/strong><\/p>\n\n\n\n
    Tuples are ordered, immutable collections of items.<\/p>\n\n\n\n
    coordinates = (10.0, 20.0)<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Mapping Type<\/strong><\/h2>\n\n\n\n
    1. Dictionaries<\/strong><\/p>\n\n\n\n
    Dictionaries are unordered collections of key-value pairs.<\/p>\n\n\n\n
    student = {"name": "Alice", "age": 21, "course": "Computer Science"}<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Set Types<\/strong><\/h2>\n\n\n\n
    1. Sets<\/strong><\/p>\n\n\n\n
    Sets are unordered collections of unique items.<\/p>\n\n\n\n
    fruits = {"apple", "banana", "cherry"}<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    2. Frozensets<\/strong><\/p>\n\n\n\n
    Frozensets are immutable sets.<\/p>\n\n\n\n
    frozen_fruits = frozenset({"apple", "banana", "cherry"})<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Boolean Type<\/strong><\/h2>\n\n\n\n
    1. Booleans<\/strong><\/p>\n\n\n\n
    Booleans represent True<\/code> or False<\/code> values.<\/p>\n\n\n\n
    is_active = True\nis_student = False<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Binary Types <\/strong><\/h2>\n\n\n\n
    1. Bytes<\/strong><\/p>\n\n\n\n
    Bytes represent sequences of byte (8-bit) values.<\/p>\n\n\n\n
    byte_data = b"Hello"<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    2. Byte Arrays<\/strong><\/p>\n\n\n\n
    Byte arrays are mutable sequences of byte values.<\/p>\n\n\n\n
    byte_array = bytearray(5)<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    3. Memory Views<\/strong><\/p>\n\n\n\n
    Memory views allow you to access the internal data of an object that supports the buffer protocol.<\/p>\n\n\n\n
    memory_view = memoryview(byte_array)<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
