Here is my code to replace:

def getGuessedWord():
    pos = word.index(guessword.lower())
    print(pos)
    global words             
    words = words[:pos]+ guessword.lower() +words[pos+1:]

My solution to your overall problem of filtering out guessed letters is the following set of functions:

guessed_letters = set()
def guess(letter):
    global guessed_letters
    guessed_letters.add(letter)

def filter_letter(letter):
    if letter in guessed_letters:
        return letter
    else:
        return '-'

def filtered(words):
    for word in words:
        output = ''
        for letter in word:
            output += filter_letter(letter)
        yield output

or more compactly:

guessed_letters = set()
def guess(letter):
    global guessed_letters
    guessed_letters.add(letter)

def filter_letter(letter):
    return letter if letter in guessed_letters else '-'

def filtered(words):
    return [''.join(map(filter_letter, word)) for word in words]

such that:

>>> words = "bubbly water".split()
>>> guess('a')
>>> ' '.join(filtered(words))
'------ -a---'
>>> guess('b')
>>> ' '.join(filtered(words))
'b-bb-- -a---
