Hi Alasdair,

I understand that you mean
  sage: lst=[[1,2],[3,4],[5,6]]
  sage: for x in lst:
  ....:     lstc=copy(lst)
  ....:     lstc.remove(x)
  ....:     print lstc
  ....:
  [[3, 4], [5, 6]]
  [[1, 2], [5, 6]]
  [[1, 2], [3, 4]]

Probably you got onle "None" printed. This is because the return value
of lstc.remove(x) is None. The remove() method changes the list in
place.

Best regards,
  Simon
