New submission from Yclept Nemo <orbisvi...@gmail.com>: Python 3.3 expands the range class but I would find some additional methods useful:
min/max: provides O(1) time __and__: provides intersection: Range(...) & Range(...) examples: intersection #1: a=Range.Range(9,58,4) b=Range.Range(15,69,6) c=a&b print(c) Range(21, 69, 12) list(c) [21, 33, 45, 57] intersection #2: a=Range.Range(-75,-7,4) b=Range.Range(-111, -26, 6) c=a&b print(c) Range(-75, -15, 12) list(c) [-75, -63, -51, -39, -27] intersection #3: a=Range.Range(58,9,-4) b=Range.Range(15,69,6) c=a&b print(c) Range(0, 0, 1) list(c) [] I've attached an example Range class implemented in python that includes the min, max, and __and__ functions. It should be useful because the intersection algorithm is complicated. Extending the range class was a requirement for a python 3.2 project and hopefully python 3.4 can benefit. ---------- components: None files: Range.py messages: 164333 nosy: Yclept.Nemo priority: normal severity: normal status: open title: Range: Additional Methods (min/max/__and__) type: enhancement versions: Python 3.4 Added file: http://bugs.python.org/file26209/Range.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15224> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
