Programming Assignment 6 (Hangman)

Write a Python program to implement the "Hangman" game of guessing phrases. A sample session is shown here.

This program will use the following Python Class (PhraseBank.py) to initialize a phrase bank from a file provided in sys.argv[1], retrieve the next phrase, get and set topic, as well as retrieve the list of all topics.

A sample file containing topics and phrases within each topic is available at phrases.txt. This file will contain a topic line that begins with 2 "*"s followed by a topic. The lines that follow will be the phrases (one per line) under that topic. This pattern may be repeated for several topics.

import random

class PhraseBank:

  def __init__(self,fname):
    pass

  def next_phrase(self,topic):
    pass
 
  def get_all_topics(self):
    pass

Some Tips

1. In the main program (Hangman.py), you should use a variable:

   remaining_letters = "A B C D E F G H I J K L M N O P Q R S T U V W X Y Z "
   

   which will keep track of the remaining letters of the alphabet that have not been used by the user.

2. It will be useful to devise the following functions to compartmentalize the code:

     play_one_round: plays one round of the game
     replace_by_stars: takes target phrase and replaces all remaining letters by *
     test_if_win_or_loss: checks to see if win or loss and prints appropriate message
     get_valid_guess: repeatedly prompts user for their guess until they provide one of the remaining letters
