I've written this code that seems to work and I'd like to know how to get
the record that causes the abort. Apparently 'executemany' doesn't
support lastrow? And if it doesn't, any suggestions?

Thanks for the detailed explanation.
I've sort of used a dict of this sort {'a': [1,2,'fff'] } in

What's the best way to append to the list which is the value to a dict
key?
I did the following based on the docs and I'm not sure why it works
>>> b = { 'a': [4, 5]}
>>> list.append(b.get('a'),'c')
>>> b
{'a': [4, 5, 'c']}
>>>
as in, shouldn't it be
b['a'] = list.append(b.get('a'),'c')

I was wondering whether there is a faster/better/cleaner way of
element wise operations of arbitrarily nested list. I wrote something
like this for 1 level nested lists and am wondering whether there are
any good idioms in python. I did this after a ridiculous amount of
bad thinking/missteps in
Can someone point me to a good intro on OO in Python? If it does OO
basics too, even better, assuming no prior knowledge of Object
Orientation.

Thanks for that, I kept thinkin
I was under the impression that you have to define the attributes of
the class before using it in an instance. Following the book
'thinking in Python',
>>> class Point:
... """pts in 2d space"""
...
>>> print Point
__main__.Point
>>> b = Point()
>>> b.x =3
>>> b.y =4
>>> print b.y
4

While trying out code, I have trouble following the difference between
return True vs print True and the same with False. If I use return
for the True/False statements, nothing gets printed. Why? And if I
add a print before the function call I get an output like
>>>True
None
