Data Types in Programming

Data types are the building blocks of programming. They define what kind of data can be stored and manipulated in a program. Understanding data types is crucial for any programmer.

Common Data Types

Here's a list of common data types you might encounter:

• Integer (int): Whole numbers without a decimal point. Example: 5, -3, 0.
• Float (float): Numbers with decimal points. Example: 3.14, -0.001.
• Boolean (bool): True or false values. Example: True, False.
• String (str): Textual data. Example: "Hello, world!".
• List (list): Ordered collection of items. Example: [1, 2, 3].
• Dictionary (dict): Unordered collection of key-value pairs. Example: {"name": "Alice", "age": 25}.

Usage Examples

Here are some examples of how data types are used:

• Integer:

  number = 5
  print(number)
  

• Float:

  pi = 3.14
  print(pi)
  

• Boolean:

  is_valid = True
  print(is_valid)
  

• String:

  message = "Welcome to our website!"
  print(message)
  

• List:

  numbers = [1, 2, 3, 4, 5]
  print(numbers)
  

• Dictionary:

  person = {"name": "Alice", "age": 25}
  print(person)
