It's not necessarily true that the environment variable is not set just because the key is not in os.environ. In this example my del did not change the environment variable: >>> import os >>> os.environ['TMPDIR'] '/var/folders/kf/0v7kz3ps62dg11v9rq0sz35m0000gn/T/' >>> del os.environ['TMPDIR'] >>> os.environ['TMPDIR'] Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<frozen os>", line 678, in __getitem__ KeyError: 'TMPDIR' ---------- nosy: +iritkatriel _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44264> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
