1. What is a Variable?

A variable is a name that holds a reference to a data object. Python allows you to create variables and assign values without needing to declare their types explicitly (Python uses dynamic typing).

Syntax for Declaring Variables:

variable_name = value

Example 1:

age = 30  # Integer
name = "Alice"  # String

Here:

  • age holds an integer value of 30.
  • name holds a string value "Alice".

Example 2:

is_active = True  # Boolean
height = 5.9  # Float

Here:

  • is_active is a boolean variable set to True.
  • height is a float variable set to 5.9.
