# This is a traditional hangman game made for an online course.
# The code toward the top was provided.
# I wrote the code below "# end of helper code" with conceptual guidance from the problem set.
# This game depends on a "words.txt" file
# that it randomly draws its secret word from
# for each game (the word that the player is guessing).

    take a while to finish.
