For each of the below items, be sure to write your code in Spyder (or whatever Python application
you are using) and test them out by running them with appropriate function calls. Then paste your
function for each item into your submission document (you will just submit one document -- no
Python files).
i. Write a function named addFive(x) that takes a number x and returns x plus 5
ii. Write a function named combine(x, y) that takes two numbers x and y and returns the sum of
those two numbers.
iii. Write a function named sameEnds(word) that takes a string and returns True if the first and last
letter of the string are the same (e.g., "pop"), False if not (e.g., "pop!")
iv. Write a function named average(list) that takes a list of numbers and returns its mean.
