I don't think it is complaing about the parenthesis, but rather the
space between print and the functional parens:

print "foo"

uses print as a built in.  You can also call print as a function:

print("foo").

You are giving:

print ("foo").

The warning is just saying, hey I assumed you meant that as a function.
Take away the space, and the warning will go away.  At least it did for
me.
