A warning is an indication of possible bugs in your code. If you do not close file explicitly, and it is closed by the garbage collector, the time of closing is undeterminated. This can lead to exhausting of file descriptors if you have a lot of opened files waiting for closing in reference loops. If you want to get rid of warnings, use a corresponding warning filter for ignoring specific warnings. Or better rewrite your code in a way that file closing is deterministic. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46304> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
