[Tutor] IF statements

[WM]

I used to do Basic and enjoyed it.  Someone said Python was a vastly 
better language than Visual Basic, which I considered playing with.  So 
I sought to give it a go but struck a sticking point very early.
I am now going through the Python tutorial.  All went well until I came 
to IF.  The code below was not written by me.  It is a copy/paste job 
from the tutor.  I do not have any idea what is going wrong.

IDLE 2.6     
 >>>
 >>>
 >>> x = int(raw_input("Please enter an integer: "))
Please enter an integer: 42
 >>> if x < 0:
...      x = 0
...      print 'Negative changed to zero'
... elif x == 0:
...      print 'Zero'
... elif x == 1:
...      print 'Single'
... else:
...      print 'More'
...
More
12
SyntaxError: invalid syntax
