Replace four letter word in python

Question

I am trying to write a program that opens a text document and replaces all four letter words with **. I have been messing around with this program for multiple hour

Answer 1

def censor(filename):
"""Takes a file and writes it into file censored.txt with every 4-letterword replaced by xxxx"""
infile = open(filename)
content = infile.read()
infile.close()
outfile = open('censored.txt', 'w')
table = content.maketrans('.,;:!?', '      ')
noPunc = content.translate(table) #replace all punctuation marks with blanks, so they won't tie two words together
wordList = noPunc.split(' ')
for word in wordList:
    if '\n' in word:
        count = word.count('\n')
        wordLen = len(word)-count
    else:
        wordLen = len(word)
    if wordLen == 4:
        censoredWord = word.replace(word, 'xxxx ')
        outfile.write(censoredWord)
    else:
        outfile.write(word + ' ')
outfile.close()
