How to use the markovify.split_into_sentences function in markovify

def sentence_split(self, text):
    lines = text.splitlines()
    text = " ".join([self._prepare_text(line) for line in lines if line.strip()])

    return markovify.split_into_sentences(text)

        # split everything up by newlines, prepare them, and join back together
        lines = text.splitlines()
        text = " ".join([self._prepare_text(line)
            for line in lines if line.strip()])

        return markovify.split_into_sentences(text)
