Ascii art hangman [duplicate]

Question

Although there was a hangman competition before, I don't feel it was beautiful enough. The challenge is to implement a clone of http://inventwithpython.com/chapter9.html but as in the previous competition you can input the list of words in any way you want. The main difference is therefore just that you have to draw the gallows in ascii as the game goes on.

Answer 1

Python 3

You will need to put the lists in a folder named wordlists, which is placed in the same folder as the source. You can download the full .zip here: https://github.com/OddLlama/ascii-gallows-club.

This program allows 7 guesses until completion, and allows guessing the full word in one blow, if you think you know it. It has a debug mode, where you enter 'debug' instead of the number of players, and does not allow you to enter a guess more than once. It also allows 2-player mode, where one player enters the word, and a second player guesses it. In this mode, the entered word does not display while being typed. Other features are score-keeping and displaying special characters (although the lists haven't been updated to represent that):

#!/usr/bin/env python3

import random # for choosing a word
import os # for finding files in wordlists directory
import textwrap # for ASCII art dedentation
import time # for sleeping at the end
import getpass # for 2 player

# grab all the filenames
categories = [f.split('.')[0] for f in os.listdir('wordlists')]

debug_mode = False
def debug(s):
  if debug_mode: print('[DEBUG] ' + s)

def print_ASCII(ascii_str):
  "Print ASCII art."
  print(textwrap.dedent(ascii_str))

def header():

def choose_category():
  "Request the user to input a category."
  for i, cat in enumerate(categories):  # print the categories & numbers
    print('%i. %s' % (i, cat))
  choice = input('Please enter a category name or number: ').lower()
  if choice.isdigit() and 0 <= int(choice) < len(categories):
    choice = categories[int(choice)]
  for i, cat in enumerate(categories):
    if choice == str(i): choice = cat
  while choice not in categories:  # loop until user enters a valid category
    choice = input('Invalid category. Try again: ')
    if choice.isdigit() and 0 <= int(choice) < len(categories):
      choice = categories[int(choice)]
  return choice

def get_word(category):
  "Retrieve a random word from a category."
  with open('wordlists/%s.txt' % category) as f: # use `with` for automatic file closure
  words = f.readlines()
  return random.choice(words).rstrip('\n').strip().lower()

def get_guess(guessed):
  "Get the user to guess a letter."
  guess = input('Guess: ').lower()
  while guess in guessed:
    guess = input('You already guessed that. Try again: ').lower()
  return guess
