Serhiy Storchaka added the comment: The "sys" file is not imported. It is read by linecache.
warnings.warn() tries to determine the file name by looking at __file__ in module's globals. If it fails, it falls back to the module name. Definitely it fails also for builtin modules, binary extensions and zipimported modules. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25493> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
