Message 228021 - Python tracker
It looks like the issue was already fixed: haypo@smithers$ ./python Python 3.5.0a0 (default:8e9df3414185, Oct 1 2014, 00:19:36) >>> invalid = 5 File "<stdin>", line 1 invalid = 5 ^ SyntaxError: invalid character in identifier The cursor is now before "=". It's not on the invalid character inside the identifier, but it's better than before ;-)
