1. Create a python program that takes an input string from a user. Analyze this string and separate all single letter words into one array, numbers into another array and all longer words into a third array.

• Use functions
• The program should continue until the user types in Exit or 0 (zero)
• Type Print to print out the results for the previous input string
• Use the given unit tests to check your work
• Hint: Use can use tuples to group your answers
• Extra practice: Delete all punctuation

2. Create two new unit tests to verify edge cases for your code
