NLTK Slot Machine

Enter Letters, Get Lucky

Process

Runs a simulation similar to a slot machine.

A user is asked to enter 3 english language letters, with a minimum of at least 1 vowel.

An NLTK Corpus Dictionary is loaded as a source of valid English language words. This list of valid words is compared to a generated list of permutations of the three letters chosen by the user, creating a list of possible valid words.

The user then "pulls a lever" using the space bar, and the three letters are randomly generated in a random order. If there is a match between the Slot Machine results and the NLTK Corpus Dictionary, the user wins.

The user may continue to play by using the space bar, or can end the simulation with any other key.

Collecting Target Letters Via User Input

    def letterCollector(self):
        cases = ["A", "E", "I", "O", "U"]
        active = bool
        while active:
            char1 = input("Enter a Vowel")
            if char1.upper() in cases:
                break
            else:
                print("Try Again, Enter A, E, I, O, or U")
        while active:
            char2 = input("Enter a Vowel or Consonant")
            if char2.isdigit():
                print("Error, please enter a letter")
            else:
                break
        while active:
              char3 = input("Enter another Vowel or Consonant")

Generate an NLTK Corpus of Valid Dictionary Words Using Collected Letters

        while checking:
            letters = LetterToWordSlotMachine().letterCollector()
            permutations = [''.join(i) for i in itertools.product(letters, repeat = 3)]
            for each in permutations:
                if each in words.words():
                    validPermutations.append(each)
            if not validPermutations:
                print("No words could be generated, please enter new letters")
            else:
                break
        print(', '.join(validPermutations))
        return letters, validPermutations

Slot Machine

    def slot_machine(self, letters, wordlist):

            c = random.choice(letters)
            result = a.upper()+b+c

                   pass
                else:
                    break
            else:
                print("Fail")
