I created this for no reason other than to see it work. For now, it steams along to a certain point and isn't too flexibile with words containing the same character more than twice. It also breaks if there is more than one set of repeating characters. I also limited the possible amount of generated words to 100,000 because it can go on forever provided you input a word larger than 9 characters.

There are many commented out print statements -- an insight to my debugging process. Once I finalize the code, I'll remove all of those.

I want to build this out with the additional option of checking against a word-dictionary to save only actual words to the results -- all customizable of course. Definitely a work in progress.

    for c in repeats:
        if repeats[c] > 1:
            repeated_character=c
            print('Repeated character: '+repeated_character)
            break
    x=0
    wordlist=[]
    for item in word:
        wordlist.append(item)
    print('Letters in word: '+str(wordlist))
    while x != 100000:
        new_word=''
        while len(new_word) != len(word):
            letter = random.choice(wordlist)
            #print(letter)
            if letter == repeated_character:
                try:
                    test = collections.Counter(new_word)
                    count=0
                    for c2 in test:

                            break
                    if count != 1:
