The NLTK tokenizer that has improved upon the TreebankWordTokenizer. This is the method that is invoked by ``word_tokenize()``. It assumes that the text has already been segmented into sentences, e.g. using ``sent_tokenize()``. The tokenizer is "destructive" such that the regexes applied will munge the input string to a state beyond re-construction. It is possible to apply `TreebankWordDetokenizer.detokenize` to the tokenized outputs of `NLTKDestructiveWordTokenizer.tokenize` but there's no guarantees to revert to the original string. u([«“‘„]|[`]+)z \1 z^\"``z(``)z([ \(\[{<])(\"|\'{2})z\1 `` z$(?i)(\')(?!re|ve|ll|m|t|s|d|n)(\w)\bz\1 \2u ([»”’])''z '' "z\s+ z([^' ])('[sS]|'[mM]|'[dD]|') z\1 \2 z)([^' ])('ll|'LL|'re|'RE|'ve|'VE|n't|N'T) u&([^\.])(\.)([\]\)}>"\'»”’ ]*)\s*$z \1 \2 \3 z ([:,])([^\d])z \1 \2z([:,])$z\.{2,}z \g<0> z[;@#$%&]z([^\.])(\.)([\]\)}>"\']*)\s*$z\1 \2\3 z[?!]z([^'])' z\1 ' z[*]z[\]\[\(\)\{\}\<\>]z\(z-LRB-z\)z-RRB-z\[z-LSB-z\]z-RSB-z\{z-LCB-z\}z-RCB-z--z -- textconvert_parentheses return_strreturncU(a[R"S[SS9 URHupEUR XQ5nM UR HupEUR XQ5nM UR upEUR XQ5nU(a&URHupEUR XQ5nM URupEUR XQ5nSU-S-nURHupEUR XQ5nM URHnUR SU5nM URHnUR SU5nM UR5$)aJReturn a tokenized copy of `text`. >>> from nltk.tokenize import NLTKWordTokenizer >>> s = '''Good muffins cost $3.88 (roughly 3,36 euros)\nin New York.
