Hi All.
I'm using psycopg2 to retrieve results from a rather large query (it
returns 22m records); unsurprisingly this doesn't fit in memory all at
once. What I'd like to achieve is something similar to a .NET data
provider I have which allows you to set a 'FetchSize' property; it
then retrieves '

To emulate the order of XP, you might be able to get away with
something like:-
sorted( myData, key=lambda L: L.replace('~',chr(0)) )
That just forces all '~'s to be before everything else.

How about decorating your list of elements with an additional value,
which indicates the weight of that element. A value of 1 will indicate

Hi Group,
If I have a CSV reader that's passed to a function, is it possible for
that function to retrieve a reference to the "fileobj" like object
that was passed to the reader's __init__? For instance, if it's using
an actual file object, then depending on the current row, I'd like to
open the f
