This week we will work with functions. For this weeks assignment, write a program that uses a function to convert miles to kilometers. Your program should prompt the user for the number of miles driven then call a function which converts miles to kilometers. Check and validate all user input and incorporate Try/Except block(s). The program should then display the total miles and the kilometers. 1. A try block. 2. A function to do the conversion. 3. A loop to prompt the user for input.
