IDLE 1.1.2
 >>> def as_excepted():
	print "The trailing comma makes the next print be ",
	print "on the same line as this one"

	
 >>> as_excepted()
The trailing comma makes the next print be  on the same line as this one
 >>>


Try putting a string behind the print statement that appears not to be 
doing anything, and you will see that it is. The first print is needed 
to clear out of the looped print's comma.

If you don't like the repetition, you could:


 >>> def one_way():
	for i in range(3):
		print i,
	print '\n'   # Explicitly request newline

	
 >>> one_way()
0 1 2

 >>>
