Copying the list elements

[psbasha]

Hi,

I am trying to assign the list elements(l1) to another list (l2).When I am trying to remove the element from l2,it is removing the element from l1.

Is there any method available to copy the list elements?So that I can avoid deleting the elements.

Sample
>>> l1 = [1,2,3,4]
>>> l2 = l1
>>> l2.remove(3)
>>> l1
[1, 2, 4]
>>> l2
[1, 2, 4]
>>>

O/P :

I need l1 = [1,2,3,4] and l2 = [1, 2, 4]
Thanks

>>> l1 = [1,2,3,4]
>>> from copy import copy
>>> l2 = copy(l1)
>>> l2.remove(3)
>>> l1
[1, 2, 3, 4]
>>> l2
[1, 2, 4]
>>>

The above statement works.But is there any other method available

>>> l1 = [1, 2, 3, 4]
>>> l2 = l1[:] # "slice" beginning to end #
>>> del l1[0]
>>> l2
[1, 2, 3, 4]
>>> l1
[2, 3, 4]
