This is actually misleading by itself, as the first statement is not a
function call in Py2:
Python 2.6.4 (r264:75706, Dec 7 2009, 18:43:55)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> print(1,2)
(1, 2)
It can, however, be made a function call through a future import in 2.6:
>>> from __future__ import print_function
>>> print(1,2)
1 2
