[web2py] Re: Print statement fails in command line script (v2.15.3)
Looks like shell.py imports print_function from __future__, which requires
use of the print() function. I suppose this should be considered a breaking
of backward compatibility, so feel free to report an issue on Github.

What python version are you running?
I have a few controller functions that I run with -S, but I don't have them
on my 2.15.3 instance at the moment. But I do have URL-accessed
controllers with print statements, and those seem fine ... 2.15.3, Python
2.7.3 (on an antique Fedora).
