#Description : I am trying to recreate the Game that I had created long time back using C++ to win a programming contest

import random       #need to generate random no.

#Describing the rules to the players
print """Welcome to this home-made game. I call it "GuessTheWord" !
The game, as its name suggests, is to guess a word. You will see the blanks representing the letters in a word. So, cue no. 1 - You know the no. of letters in the word.

You need to enter one letter at a time as your guess. If the letter exists in the guess word, the blanks will be replaced for each occurrence of the entered letter.

Press Ctrl+c to quit the game.

Now lets start the game !!!"""
