Iteration weirdness

[Dave Opstad]

I'm running into a strange behavior under Python 2.3.3:

------------------------------------------

d = {-1: 'cv', -2: 'se', -3: 'se'}
d {-1: 'cv', -2: 'se', -3: 'se'}
len(d) 3
[d[-1], d[-2], d[-3]] ['cv', 'se', 'se']
[d[-1-i] for i in len(d)]

Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: iteration over non-sequence
------------------------------------------

Can someone enlighten me as to why the list comprehension gives an
error, but the simple list construction case works fine?

Thanks for any help!

Never mind, brain freeze on my part. Should have been:

[d[-1-i] for i in range(len(d))]

Sigh...sorry to bother everyone.
