Create a Python program that takes a list of words as input and returns the longest word(s) from the list. Your program should ignore punctuation and consider letters only. If there are multiple words with the same maximum length, return all of them.
longest_words(["Hello", "world", "Coding", "is", "fun!"])
# Output: ["Hello", "world", "Coding"]
longest_words(["Python", "Java", "C++", "JavaScript"])
# Output: ["Python", "JavaScript"]
import codewars_test as test
# TODO Write tests
import solution # or from solution import example
# test.assert_equals(actual, expected, [optional] message)
@test.describe("Example")
def test_group():
@test.it("test case")
def test_case():
test.assert_equals(1 + 1, 2)
