R. David Murray <rdmur...@bitdance.com> added the comment: os.environ is not a dictionary, so it isn't all that surprising that a shallow copy doesn't behave like a shallow copy of a dictionary. deepcopy does what you'd expect, as does os.environ.copy().
Perhaps it is worth improving this by adding a __copy__ method to os.environ. Someone would need to propose a patch, and it would be an enhancement. ---------- nosy: +r.david.murray type: behavior -> enhancement versions: +Python 3.4 -Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15373> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
