def sent_tokenize(text, tokenizer=None):
_tokenizer = tokenizer if tokenizer is not None else NLTKPunktTokenizer()<EOL>return SentenceTokenizer(tokenizer=_tokenizer).itokenize(text)<EOL>
Convenience function for tokenizing sentences (not iterable).

    If tokenizer is not specified, the default tokenizer NLTKPunktTokenizer()
    is used (same behaviour as in the main `TextBlob`_ library).

    This function returns the sentences as a generator object.
