Answer 20

Output Like a Human [challenge]
Sometimes we want our code output to be more like it came from a human rather than from a machine.
Write a code that takes any collection of things, e.g. list, tuple, set, generator expression, and prints the contents the way a human list is written using "," and "and".
Remember sets are unordered and generator expressions have no length!
Examples:
[1] -> 1
[1, 2] -> 1 and 2
[1, 2, 3] -> 1, 2 and 3
[1, 2, 3, 4] -> 1, 2, 3 and 4
