Nope! `print` is a statement in all 1.x and 2.x versions of Python.
When you do, say,
print(1)
before Python 3.x, you're not calling a print function with an
argument of 1, you're giving the expression (1) to the print
statement. (1) is the same thing as 1, so it just prints "1".
Maybe the difference is clearer here:
print(1,2,3)
Before 3.x, tjat's the same as
_x = (1, 2, 3)
print _x
That is, it's not passing arguments 1, 2 and 3 to a print function,
it's giving a single expression - the 3-tuple (1, 2, 3) - to the print
statement - and is very different from
print 1, 2, 3
(which gives 3 expressions - not just 1 - to the print statement).
It's really the same as doing, e.g.,
return(1)
`return` and `print` are statements, and tacking "(1)" on does not
magically turn either into a function call, it's just adding redundant
parentheses to the expression "1".
