Others have already solved the immediate problem, but I'd just like to
make a brief comment abou

Yes- I can see that my_list and mops, being outside def __init__()
only get created once, hence the confusion.
Surely def __init__() gets called each time an instance is created
however? But the snag is that if they have default values set these are
shared between all instances, even if they are,

Similar to the example I gave, the lists my_list and mops shown above are
executed just once: when your
Ah - I have been very silly indeed!
I had not realised that by creating my lists outside of the
def__init___() constructor they would always be class rather than
instance variables, and so there was only one of them when I referred
to it. Thanks to Erik and Chris for your help!

Ah - ok. In fact I simply had:

Hello...
I have a dictionary, where each value is a seperate instance of the
same class:
self.mop_list[record_number]=record(self.mops[:])
In my case I know that record_number takes the values 0,3,and 7 thanks
to a loop, giving me three instances of the record class instantiaterd
with some data
