The sort() function for lists supports passing in a custom comparison function, however none of the functions in bisect() support this. The method used by bisect to find the proper insertion point is not documented, but I guess the module relies on a natural ordering for the items, or on the items of the list implementing __cmp__. I suggest adding a 5th argument, with keyword 'cmp', to the functions in the 'bisect' module that would allow supplying a custom comparison function, as for 'sort'. bisect_left( list, item[, lo[, hi]][,cmp]) bisect_right( list, item[, lo[, hi]][,cmp]) bisect(...) insort_left( list, item[, lo[, hi]][,cmp]) insort_right( list, item[, lo[, hi]][,cmp]) insort(...) ---------------------------------------------------------------------- Comment By: Matt Fleming (splitscreen) Date: 2006-04-03 12:57 Message: Logged In: YES user_id=1126061 See patch #1462228. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=355470&aid=1451588&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
