Language/Type: Python dict collections

Write a function named has_three that accepts a list of strings as a parameter and returns True if any string value occurs at least 3 times in the list. For example, in the list ["to", "be", "or", "be", "to", "be", "hamlet"], the word "be" occurs 3 times, so your function would return True if passed that list. Use a dict as auxiliary storage to help solve the problem. Do not modify the list that is passed in.

Function: Write a Python function as described, not a complete program.
