I was in a job interview just this week where my interviewer stated "you dealt with Python 2-3 phase? That's crazy, we're still dealing with it now". That was beyond the silly parens after a print statement.
I was at my job a few weeks ago working on a project where I'm the expert on scripting bulk changes in a certain modeling software when a non-programming project manager asked me if Perl is obsolete and why don't I use Python. The upgrade must not have done all that much damage to Python.
