Terry J. Reedy <tjre...@udel.edu> added the comment: The intro paragraph currently (3.2a) consists of "This module provides generic (shallow and deep) copying operations."
This could be expanded to ''' Assignment statements create bindings between a target and an object. They never duplicate or copy an existing object. For collections that are mutable or contain mutable items, a copy is sometimes needed so one can change one copy without changing the other. Sequences can be shallow copied by slicing the entire sequence(s[:]). (See below for the meaning of 'shallow'.) Some objects can be shallow copied with their class constructors (tuple, list, set, dict). This module provides generic shallow *and* deep copying operations. The latter is not otherwise available in an single operation or call.''' ---------- nosy: +tjreedy versions: +Python 3.1 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9021> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
