Unless you are doing some strange GUI type things it should work at
the >>> prompt too. (Sometimes you need an extra line - that could
fox beginners I suspect, if his examples contain multiple statements)

You shouldn't need to use an editing window, but the >>> prompt
does execute each line 9or block) in turn thus:

x=0
for n in range(5):
    x = n+x
print x

looks like this in IDLE:

>>> x=0
>>> for n in range(5):
    x = n+x
                                            <--Extra line here!
>>> print x
10
>>>

Is that the kind of thing you are seeing?
