Problem Three:

Valid Words You now have a large portion of this game complete. Its now necessary to develop a method to test whether the word is valid. There are two criteria. The word must be in the word list. Additionally, the letters need to be in the players hand. Implement the function word_is_valid to return true if both criteria are met and false if either is not met. When you have finished solving this problem, use the testing files test_word_validity. Like the other problems, ensure that develop additional unit tests for any boundaries not assessed.

It has to be solved in python.
