Raymond Hettinger <[EMAIL PROTECTED]> added the comment: Rejecting the key-function patch in favor of the current typical approach of heapifying tuples that link a priority level with individual records. I've been a heavy user of the module and one of its principal maintainers. To date, I've seen very little need for key- function argument.
Use cases aside, there is another design issue in that the key-function approach doesn't work well with the heap functions on regular lists. Successive calls to heap functions will of necessity call the key- function multiple times for any given element. This contrasts with sort () where the whole purpose of the key function was to encapsulate the decorate-sort-undecorate pattern which was desirable because the key- function called exactly once per element. ---------- resolution: -> rejected status: open -> closed __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1904> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
