If the code is saved in a file, yes, but not in an interactive interpreter. This is not actually related to IDLE, but to the fact that inspect.getsource merely finds the __file__ attribute of the module object for its argument. If a module object has no file, the error message indicates that it’s a built-in module (like sys), but this fails to take into account the special __main__ module in an interactive interpreter. It might be worth it to improve the error message, and in any case the documentation can be improved. ---------- stage: -> needs patch title: inspect.getsource fails to get source of local classes -> Document that inspect.getsource only works for objects loaded from files, not interactive session versions: +Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12920> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
