get_ticket.py

'''Python Project: 
Calculate Movie ticket price.
    * Ask user's age.
    * If the age is less than 3 the ticket is free.
    * If the age is between 4 - 12 the amount is 50%.
    * If the age is more than 12, the amount is 100%
    * Catch the error if the user inputs any wrong data.
