The above doesn't allow comma after the first instance of pattern2 and
it doesn't allow space after either instance. Here is a version that
passes your tests:
pattern3 = '''
^{
(
(%s
| {%s}) # Possible to have 1 level of nested lists
,?\s*)* # Items are comma-delimited, except for the last item
}$
''' % (pattern2, pattern2)
You might want to look at doing this with pyparsing, I think it will
make it easier to get the data out vs just recognizing the correct pattern.
