Write a program voting_age.py that askes the user to enter their age, and then prints out a message that's appropriate for them.
If the user is old enough to vote (18 years old), the program should display a couple of lines letting the know that they can vote, and that they should vote!
If the user is not old enough to vote, calculate how many years they have until they can vote and print out how long they'll have to wait.
Sample interactions:
Enter your name: Marisa
Enter your age: 16
You're not old enough to vote yet, Marisa.
You'll have to wait 2 more years.
Enter your name: Emilia
Enter your age: 37
You're old enough to vote, and I hope you do!
