Data types are the building blocks of programming. They define the kind of data that can be stored and manipulated within a program. Understanding different data types is crucial for writing efficient and effective code.

Common Data Types

Here are some of the most common data types used in programming:

  • Integer (int): Represents whole numbers, both positive and negative.
  • Floating-point (float): Represents numbers with decimal points.
  • Boolean (bool): Represents true or false values.
  • String (str): Represents text data.
  • List: A collection of items that can be of different types.
  • Tuple: An ordered collection of items that cannot be modified.
  • Dictionary: A collection of key-value pairs.

Example

Here's an example of how you can declare variables of different data types in Python:

age = 25          # Integer
height = 5.9      # Floating-point
is_student = True # Boolean
name = "Alice"    # String
grades = [90, 85, 88] # List
info = (name, age) # Tuple
student_details = {"name": "Alice", "age": 25} # Dictionary
