Various types of data types in python


🔢 Numeric Types

Used for storing numbers:

  • int: Integer values, e.g., 42, -7
  • float: Floating-point numbers (decimals), e.g., 3.14, -0.001
  • complex: Complex numbers, e.g., 2 + 3j

🔡 Text Type

Used for textual data:

  • str: A sequence of characters, e.g., "hello world"

📦 Sequence Types

Ordered collections:

  • list: Mutable, ordered, e.g., [1, 2, 3]
  • tuple: Immutable, ordered, e.g., (1, 2, 3)
  • range: Represents a range of values, e.g., range(0, 10)

🔑 Mapping Type

Used for key-value pairs:

  • dict: e.g., {"name": "Ramesh", "age": 30}

🧮 Set Types

Collections of unique elements:

  • set: Unordered, mutable, no duplicates, e.g., {1, 2, 3}
  • frozenset: Immutable version of a set

Boolean Type

  • bool: Logical values True or False

🪙 Binary Types

Used to handle binary data:

  • bytes: Immutable sequence of bytes
  • bytearray: Mutable version of bytes
  • memoryview: Access internal data of objects without copying

Want to explore examples of each, or dive deeper into when to use which type? I’d be happy to break it down even further.

Examples
🔢 Numeric Types

  • int:pythonage = 30
  • float:pythonpi = 3.14159
  • complex:pythonz = 2 + 5j

🔡 Text Type

  • str:pythongreeting = "Hello, Ramesh!"

📦 Sequence Types

  • list:pythonfruits = ["apple", "banana", "cherry"]
  • tuple:pythoncoordinates = (10.0, 20.0)
  • range:pythonnumbers = range(1, 6) # 1 to 5

🔑 Mapping Type

  • dict:pythonperson = {"name": "Ramesh", "city": "Hyderabad", "age": 30}

🧮 Set Types

  • set:pythonunique_numbers = {1, 2, 3, 2} # duplicates ignored
  • frozenset:pythonfrozen = frozenset(["python", "java", "python"])

Boolean Type

  • bool:pythonis_active = True

🪙 Binary Types

memoryview:pythonview = memoryview(b"example")

bytes:pythondata = b"hello"

bytearray:pythonmutable_data = bytearray([65, 66, 67])

    The Fractions module in Python is a built-in module that provides support for rational number arithmetic. It allows you to work with fractions (like 1/2, 3/4, etc.) exactly, without the precision issues that can occur with floating-point numbers. What Problems Does It Solve? Problem with Floating-Point Numbers: python # Floating-point precision issue print(0.1 + 0.2) # Output:…

  • Global And Local Variables

    Global Variables In Python, a global variable is a variable that is accessible throughout the entire program. It is defined outside of any function or class. This means its scope is the entire file, and any function can access and modify its value. You can use the global keyword inside a function to modify a…

  • Static Methods

    The primary use of a static method in Python classes is to define a function that logically belongs to the class but doesn’t need access to the instance’s data (like self) or the class’s state (like cls). They are essentially regular functions that are grouped within a class namespace. Key Characteristics and Use Cases General…
