Ezio Melotti <ezio.melo...@gmail.com> added the comment: Default args are evaluated when the module is imported, if the arg is a function call, the function is called. You can see how the file is created just after the import, you don't even need to call help().
This behavior is documented here: http://docs.python.org/tutorial/controlflow.html#default-argument-values The doc doesn't mention explicitly function calls, that could be added. ---------- components: -Interpreter Core nosy: +ezio.melotti versions: -Python 2.5, Python 2.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6148> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
