Hello,
When I make a list with list comprehensions, I get what I believe are
incorrect results. I made a short example that shows what I'm talking
about. I'm not sure if this is a bug in the iterator, or if this behavior
is by design.
Thanks,
Craig

table = hFile.createTable('/', 'table', Example)

entry['col1'] = random.randint(0, 5)
entry['col2'] = random.randint(0, 5)

(2, 0)
that is fine

print l

"""

(5, 2)
this is really unexpected (for me)
