strange list.remove behaviour in loops

[peter]

hi,

look at the following simple example:

Python 2.2.1 (#1, Jul 29 2002, 23:15:49)
>>> A = [1,2,3,4,5,6,7,8,9]
>>> for a in A:
...     print a
...     A.remove(a)
...
1
3
5
7
9

instead of removing the actual item from the list it removes the next
one. is this by design? if yes how can i work around it. i don't
really want to clone the list and remove from the clonelist instead.
