Python Variables and Data Types

What are Variables?
Variables are used to store data. In Python, you do not need to declare the type of variable; it is assigned automatically.

Basic Data Types: Integers, Floats, Strings, Booleans
Python includes several built-in data types:

  • int for integers
  • float for decimal numbers
  • str for text
  • bool for true/false values

Example:

age = <span class="hljs-number">25</span> <span class="hljs-comment"># Integer</span>
height = <span class="hljs-number">5.9</span> <span class="hljs-comment"># Float</span>
name = <span class="hljs-string">"Alice"</span> <span class="hljs-comment"># String</span>
is_student = <span class="hljs-literal">True</span> <span class="hljs-comment"># Boolean</span>

Type Conversion
Python allows for easy type conversion with functions like int(), float(), str(), etc.
