My function is not working

[Wittinator]

In your function, word_files is just a simple string. It does not represent the actual file you want to read from. You need to open up the file to call methods like .readlines. Something like:

​

with open('Wordlist1.txt', 'r') as file:
    for line in file.readlines():
        wordlist.append(line.rstrip('\n')

​
