New submission from Andrew Hays <m...@andrewhays.net>:
[{}]*3 should produce a list of dictionaries that are 3 length long, which it
does. However, one would expect that if you assign something to the keyword
'abc' in the first dicitonary (e.g., x[0]['abc'] = 'def') that the other
dictionaries would remain blank (e.g., x = [{'abc': 'def'}, {}, {}]. However,
it appears that each dictionary is filled (e.g., x = [{'abc':'def'},
{'abc':'def'}, {'abc':'def'}]).
Creating a list of dictionaries like this [{}, {}, {}] or appending a
dictionary to a list like this list.append({}) does NOT produce this same
effect, it produces the desired effect.
