When tokenizing using a particular delimiter string, use the string ``split()`` method directly, as this is more efficient. The simple tokenizers are *not* available as separate functions; instead, you should just use the string ``split()`` method directly: >>> s = "Good muffins cost $3.88\nin New York. Please buy me\ntwo of them.\n\nThanks." >>> s.split() # doctest: +NORMALIZE_WHITESPACE ['Good', 'muffins', 'cost', '$3.88', 'in', 'New', 'York.', 'Please', 'buy', 'me', 'two', 'of', 'them.', 'Thanks.'] >>> s.split(' ') # doctest: +NORMALIZE_WHITESPACE ['Good', 'muffins', 'cost', '$3.88\nin', 'New', 'York.', '', 'Please', 'buy', 'me\ntwo', 'of', 'them.\n\nThanks.'] >>> s.split('\n') # doctest: +NORMALIZE_WHITESPACE ['Good muffins cost $3.88', 'in New York. Please buy me', 'two of them.', '', 'Thanks.'] The simple tokenizers are mainly useful because they follow the standard ``TokenizerI`` interface, and so can be used with any code that expects a tokenizer. For example, these tokenizers can be used to specify the tokenization conventions when building a `CorpusReader`. )StringTokenizer TokenizerI)regexp_span_tokenizestring_span_tokenizec\rSrSrSrSrSrg)SpaceTokenizer*aTokenize a string using the space character as a delimiter, which is the same as ``s.split(' ')``. >>> from nltk.tokenize import SpaceTokenizer >>> s = "Good muffins cost $3.88\nin New York.
