i have a string word = "degree/nn"; what want remove "/nn" part of word , take word "degree" . i have following conditions: the length of word can different in different occasions.

i search lucene index edit distances. example, say, there document field first_name; want documents first names 1 edit distance away from, say, 'john'. i know lucene supports fuzzy searches (first_name:john~) , takes number between 0 , 1 control fuzziness. problem (for me) number not directly translate edit distance. , when values in documents short strings (less 3 characters) fuzzy search has difficulty finding them. example if there document first_name 'j' , search first_name:i~0.0 don't back. in lucene's fuzzyquery, cannot specify extact distance. can specify value of "fuzziness" between 0 , 1 values closer 0 indicate broad match , values closer 1 indicate narrow match. formula "fuzziness" follows. (from lucene in action) http://bit.ly/9hdvuf from formula, can work approximate fuzziness given value of distance. so, stackoverflow matched stackunderflow , @ distance of 3, fuzziness required approximately 0.77.

why did creators of java use name "class" classes in java? term come from? java didn't invent name class - used in languages prior, c++. i think name "class" refers class of objects, in classification (or type). , object instance of type. here first definition of "class" dictionary.com: a number of persons or things regarded forming group reason of common attributes, characteristics, qualities, or traits; kind; sort. so right in line know class in computer science - "characteristics/qualities/traits" being fields , methods.

hello pythoneers: following code mock of i'm trying do, should illustrate question. i know if dirty trick picked java programming, or valid , pythonic way of doing things: i'm creating load of instances, need track 'static' data of instances created. class myclass: counter=0 last_value=none def __init__(self,name): self.name=name myclass.counter+=1 myclass.last_value=name and output of using simple class , showing working expected: >>> x=myclass("hello") >>> print x.name hello >>> print myclass.last_value hello >>> y=myclass("goodbye") >>> print y.name goodbye >>> print x.name hello >>> print myclass.last_value goodbye so acceptable way of doing kind of thing, or anti-pattern ? [for instance, i'm not happy can apparently set counter both within class(good) , outside of it(bad); not keen on having u...
