a)

>>> lst1 = [1, 3]

>>> lst2 = lst1[:]

>>> lst2.append(5)

b)

>>> lst1 = [1, 3]

>>> lst2 = lst1

>>> lst1.append(5)

>>> lst1 = [0]

c)

>>> a = [[1, 2, 3], ['a', 'b']]

>>> b = a

>>> b.append(99)

d)

>>> a = [[1, 2, 3], ['a', 'b']]

>>> b = a[:]

>>> b.append(99)

e)

>>> a = [[1, 2, 3], ['a', 'b']]

>>> b = a[:]

>>> b[0].append(99)

L = [[1, 2], [3, 4], [5, 6]] for item in : item[1] = 88 print(L) id22 1,88 id58 id23 3, 88 item id24 id 24 5, 88 id58 [id22, id23, id 24 ] Output: [[1,88] , [3, 88], [5, 88]] L = [[1, 2], [3, 4], [5, 6]] for item in : item[1] = 88 print(L) id22 1,88 id58 id23 3, 88 item id24 id 24 5, 88 id58 [id22, id23, id 24 ] Output: [[1,88] , [3, 88], [5, 88]]
