Updating a variable with for loops
You're planning to hold a party so you can show off your playlist to friends and family. You've hired a venue that has a maximum capacity of 30 people, and you'd like to keep track of tickets sold.
This is a perfect opportunity to use a for loop - it will increment the value of a variable each time a ticket is sold and then print a statement once the event is sold out.
