 # Wordle in Python
 
 Your task for the final assignment is to implement a [Wordle](https://en.wikipedia.org/wiki/Wordle)

 `5_letter_words.txt` [[1]](https://www-cs-faculty.stanford.edu/~knuth/sgb.html).
 It contains more than 5.700 five letter words. In order to build your
 version of Wordle perform the following steps:
 
 1. Implement a function `word_list()` that reads the `5_letter_words.txt` file and returns a list
    of the words in the file.
