Predict the output of following two parts. Are the outputs same? Are the outputs different? Why?

(a)

L1, L2 = [2, 4] , [2, 4]
L3 = L2                 
L2[1] = 5               
print(L3)               

(b)

L1, L2 = [2, 4] , [2, 4]
L3 = list(L2)
L2[1] = 5
print(L3)

Find the errors:

1. L1 = [1, 11, 21, 31]
2. L2 = L1 + 2
3. L3 = L1 * 2
4. Idx = L1.index(45)

Find the errors:

L1 = [1, 11, 21, 31]
An = L1.remove(31)
print(An + 2)

Find the errors:

L1 = [3, 4, 5]
L2 = L1 * 3
print(L1 * 3.0)
print(L2)
