""" Define the get_last_three_letters() function which is passed a list
of strings as a parameter. The function returns a string made up of the
concatenation of the last three letters of each word from the parameter
list which has at least three characters.  The string returned by the
function should be in lowercase characters.  If the parameter list is an
empty list, the function should return an empty string.  For example,
the following code:

print("1.", get_last_three_letters(["Jess", "Cain", "Amity", "Raeann"]))
print("2.", get_last_three_letters(["CAIn", "JessiE", "O", "ROBERT", "Geoffrey", "Li", "B"]))
print("3.", "***" + get_last_three_letters([]) + "***")
print("4.", "***" + get_last_three_letters(["A", "E", "O"]) + "***")

prints:

1. essainityann
2. ainsieertrey
3. ******
4. ******
