Understanding If Statements in Python

What is the purpose of an if statement in Python?

• To execute code conditionally based on a boolean expression.

• To repeat code multiple times.

• To create a loop for iteration.

• To define a function in Python.

How do you write a basic if statement in Python?

• If statements always execute first; else statements are never executed.
