This may be a Python version mismatch error.
In python version 2.x (and 1.x for that matter), "print" is a statement,
but it was changed to be a function in python version 3.x.
In other words, in python 2.x you can say this:
print x
print "hello there"
But in python 3.x you have to do it a little differently:
print(x)
print("hello there")
It sounds like your IDLE is running python 3, but your command line is
running python 2.
