   2. print out the string in all capital letters and print the string capitalizing each word in the string.
   3. divide the string into a list of words in the string and print out each word and the length of the word.
   4. After printing out all of the words, print out the total length of all the words. This shouldnt include the spaces in the original string.

2. Write a function called total_n_avg. The function will have one parameter that contains how many numbers to average. The function is to ask the user for the numbers. The total and average is to be computed in the function and both are to be returned to the calling program. Be sure the returned numbers are floats

Write code to call the function. Ask the user for how many numbers to total. The function is to be called until the user enters 0 for the how many numbers to total.
