Replace
alfc[iteration]=alf.copy()
with
alfc[iteration] = deepcopy(alf)
(This should work if you're using it in an interactive Sage session, but deepcopy
may not be defined in a non interactive session, so you might need to also include from copy import deepcopy
.)
See https://stackoverflow.com/questions/2541865/copying-nested-lists-in-python, for example.
