Hangman game through Python

Simple python code to implement the hangman game.The code assumes that you have a file named 'words.txt' which contains n number of words.The program randomly selects one word from the file. The user is given 8 chances to guess the word.Each word guessed by the user is added to the lettersGuessed list.Procedure isWordGuessed() is used to determine whether the guessed letter is in the secretWord.If not the number of guesses remaining is reduced by one.Procedure getGuessedWord is used to print present correctly guessed words and thier locations...
