The server doesn't like attachments so strips them off
for security. As a result we can't see the code.

Please resend, but paste the code into the body of your
message (in plain text to preserve formatting).
It would be helpful to also include your OS and
Python version.

250 of anything is not very much in computing terms
(even if your lattice is 250 cubed its still not
unusually big). But I guess it depends on what the data
elements look like.

We can't see the code but the most common operation for
adding data to a list is the append() method

mylist.append(anObject)

But we can say more when we see the code.
