Correct

Nope. You don't need a space line (you mean an empty line by that, right?), 
you can just outdent one level and continue without any empty lines 
(although in the interactive interpreter you need the empty line to end the 
block on the first indentation level). So you could do:

i = 5
while i > 0:
	print i
         i = i-1
print "That's it"

Works just fine. Other than the indentation, spacing is pretty much 
irrelevant in Python.
