>>> def foo(): ... print bar File "<stdin>", line 2 print bar ^ SyntaxError: Missing parentheses in call to 'print' It's still just basic string hackery, though. The one liner handling, for example, relies on the fact that ":<whitespace>print " and ":<whitespace>exec " are going to be uncommon outside Python 2 code being ported to Python 3, so it just looks for the first colon on the line and checks from there, without worrying about slice notation or dicts. ---------- Added file: http://bugs.python.org/file35510/issue21669_custom_error_messages_v2.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21669> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
