How do I make a random choice generator?

I'm trying to make a random choice generator, so you can ask an AI say, "one or two", and it'll give you a randomly generated answer. I get this error: "Traceback (most recent call last): File "C:/Users/Jeff/PycharmProjects/pythonProject/main.py", line 246, in answer = next(res.results).text StopIteration"

It's easy to make something choose a random choice with the options being one characters like "one or two", but I want it to be able to choose between sentences like "going to the beach or staying home", here's my code:

   words = output.split()
                            if words[1] == 'or':
                                choices = [words[0] + output.replace(words[2], '') + output.replace('or', ''), words[2] + output.replace(words[0], '') + output.replace('or', '')]
                                choice = random.choice(choices)

                                language = 'en'
                                voice = gTTS(text=choice, lang=language, slow=False)

                                voice.save("voice.mp3")
                                os.system("start voice.mp3")

                                print(choice)
