In this activity, we will write a Python program that checks whether a person is eligible to vote based on their age. In most countries, the minimum voting age is 18.

Algorithm

START
INPUT: Ask the user for their name
INPUT: Ask the user for their age
DECISION: Is age >= 18?
YES → OUTPUT: Print that the person is eligible to vote
NO → OUTPUT: Print that the person is not eligible and how many years remain
END

Flowchart for the voting eligibility checker showing start, input boxes for name and age, a diamond decision for age >= 18, a yes branch to eligible message and a no branch to not eligible message with years remaining, then end

Writing the Python Code

# Voting Eligibility Checker name = input("Enter your name: ") age = int(input("Enter your age: ")) if age >= 18: print(name + ", you are eligible to vote!") else: years_left = 18 - age print(name + ", you are not eligible to vote yet.") print("You need to wait " + str(years_left) + " more year(s).")

Understanding the Code

Code Breakdown

Line	What it Does
name = input(...)	Stores the user's name as a string
age = int(input(...))	Stores the user's age as an integer
if age >= 18	Checks if the age is 18 or more
years_left = 18 - age	Calculates how many years until the person can vote
str(years_left)	Converts the number to a string for printing

Testing the Program

Run with name = Sara, age = 20 → Should print Sara, you are eligible to vote!
Run with name = Ali, age = 15 → Should print Ali, you are not eligible to vote yet. You need to wait 3 more year(s).

Python console showing two test runs — one where Sara aged 20 is eligible and one where Ali aged 15 is not eligible with years remaining shown
