Question

Just getting into python, and so I decided to make a hangman game. Works good, but I was wondering if there was any kind of optimizations I could make or ways to clean up the code. Also, if anyone could recommend a project that I could do next that’d be cool.

import sys
import codecs
import random

def printInterface(lst, attempts):
    """ Prints user interface which includes:
            - hangman drawing
            - word updater """

    for update in lst:
        print (update, end = '')

    if attempts == 1:
        print ("\n\n\n\n\n\n\n\n\n\n\n\t\t    _____________")
    elif attempts == 2:
        print ("""

First idea: ASCII art

The things special to Python are regular expression syntax and range() function, as well as [xxx for yyy in zzz] array filler.

    import re

    def ascii_art(attempt):
        return re.sub(r'\d', '', re.sub('[0{0}].' \
            .format(''.join([str(e) for e in range(attempt + 1, 10)])), ' ', """
                3_3_3_3_3_3_
               4|      2|
               4|      2| 
             4(4x4_4X4)    2|
               5|      2|
              6/5|7\     2|
               5|      2|
              8/ 9\     2|
                      2|
                      2|
                1_1_1_1_1_1_1|1_1_1_1_1_1_
    """))

    for i in range(1, 10): 
        print(ascii_art(i)) 

Second idea: loops

Use enumerate for word reading loop. Use

for attempt in range(1, 10):
    # inside main loop
    ...
print ('you suck!')

as the main loop. Operator break should be used with care and not as replacement for for!

Unless I miss something, the structure of

    for letters in lst:
        if guess not in word:
            ...
            break
        if guess in word[i]:
            ...

will be more transparent as

    if guess not in word:
             ...
    else:
         index = word.find (guess)
         ...
