Yes, I've ran across that too a few times.

This routine copies a list of lists.
# Makes a copy of a list of lists
# Containing simple data.
def copylistlist(alist):
if type(alist) is list:
copy = []
for i in alist:
if type(i) is list:
i = copylistlist(i)
copy.append(i)
return copy
bob = [[[0, 0]]]
final = copylistlist(bob)
print 'bob:'bob
print 'Final:'final
This still doesn't create new items within the new list. but with
literal data consisting of letters and numbers, it will work.
If you are working with a data tree, you may be able to modify this to
do what you want. Just add a test in the inner loop for the data you
want to modify.
