print is simply not a function in 2.x. Abusing the Python 2.x syntax
to pretend like it is a function is terribly inconsistent when showing
Python 2.x code. It is bad style to use print() in Python 2.x. The
semantics are *not* the same when executing Python 3.x print() code in
Python 2.x. numpy does not support Python 3.x, yet.

+1 on reverting the changes.
