TOPIC 3: Conditional Statements & Loops

1. Conditional Statements

Conditional statements allow you to control the flow of your program based on specific conditions.

• if: If the condition is True, execute the code inside the block.
• elif: If the previous conditions are False, check this condition.
• else: Execute the code if all previous conditions are False.

Example 1:

age = 18
if age >= 18:
    print("You can vote!")
else:
    print("You cannot vote yet.")

Example 2:

number = 10
if number % 2 == 0:
    print("Even number")
else:
    print("Odd number")

So, what does it mean?

If a number is divisible by 2 with no remainder, then it’s an even number.

Here, 10 % 2 is 0, so the condition is True, and the program prints:

Even number

If you had:

number = 7

Then 7 % 2 is 1, so the condition is False, and it would go to the else block (if it exists), which will print:

Odd number
