CPT 180 Chapter 3 Assignment 3 Directions Using the following guidelines, create a python program. 1. Create the Collatz Sequence program as described on page 77 76 in the 2nd Edition). Name the program collatzSeq.py. 2. Add three comment lines at the top of the program that contain: a. Program Name b. Program Description C. Programmer's Name (You) 3. Add code in the program that validates the user's input and ensures it is an integer. If it is not an integer, it displays an error message and re-prompts the user. 4. The collatz() function should always receive one integer as a parameter, perform a calculation, and print out and return an integer. 5. The program should contain a loop that continues to call the collatz() function until the function returns a value of 1. 6. Add code that indicates when the program has ended. 7. See below for an Example Output. 8. Submit the collatzseq.py file into the Chapter 3 Assignment 3 Submission Folder. Hints 1. The error or exception that occurs when the int() function cannot convert a string to an integer is the ValueError exception.

If number is even, then collatz() should print number // 2 and return this value. If number is odd. then collatz() should print and return 3 * number + 1. Then write a program that lets the user type in an integer and that keeps calling collatz() on that number until the function returns the value 1. (Amazingly enough, this sequence actually works for any integer-sooner or later, using this sequence, you'll arrive at l! Even mathematicians aren't sure why. Your program is exploring what's called the Collatz sequence, sometimes called "the simplest impossible math problem.") Remember to convert the return value from input() to an integer with the int() function; otherwise, it will be a string value. Hint: An integer number is even if number % 2 == 0, and it's odd if number % 2 == 1. The output of this program could look something like this: Enter number: 3 10 5 16 8 4 2 1 Input Validation Add try and except statements to the previous project to detect whether the user types in a noninteger string. Normally, the int() function will raise a ValueError error if it is passed a noninteger string, as in int("puppy'). In the except clause, print a message to the user saying they must enter an integer
