L1 = [1, 2, 3, 4]
L2 = L1
L3 = L1.copy()
L4 = list(L1)
L1[0] = [5]
Print(L1, L2, L3, L4)
A)[5, 2, 3, 4] [5, 2, 3, 4] [1, 2, 3, 4] [1, 2, 3, 4]
B)[[5], 2, 3, 4] [[5], 2, 3, 4] [[5], 2, 3, 4] [1, 2, 3, 4]
C)[5, 2, 3, 4] [5, 2, 3, 4] [5, 2, 3, 4] [1, 2, 3, 4]
D)[[5], 2, 3, 4] [[5], 2, 3, 4] [1, 2, 3, 4] [1, 2, 3, 4]

L2 is directly assigned to L1, so changes in L1 will reflect in L2. L3 and L4 are created as copies of L1, so they won't change when L1 is modified. The first element of L1 is changed to a list [5], not the integer 5.
