Final answer:
A Python program checks if a user is eligible for voting by asking their age and then using an if-else statement to check if the age is 18 or above, indicating they're eligible to vote.
Step-by-step explanation:
To write a program in Python to check if a user is eligible for voting, we can follow these steps:
- Start by prompting the user to enter their age.
 - Check if the age entered is 18 or above, as this is often the minimum voting age in many jurisdictions.
 - Print a message indicating whether or not the user is eligible to vote.
 
Here is a simple Python program that implements these steps:
# Ask the user for their age
age = int(input("Please enter your age: "))
# Check if the user is eligible to vote
if age >= 18:
 print("You are eligible to vote.")
else:
 print("You are not eligible to vote.")
This simple program uses an 
if-else statement to determine voting eligibility based on the user's age.
