Answer 1

x = 5
y = 4
z = [1,2,3]
print (len(x*y*z))

The calcultion of len() is based on the multiplication of 5 * 4 = 20. Then list (len = 3) is multiplied with 20. if you do:

a = x * y * z

a will look like: [1,2,3,1,2,3,1,2,3,...] with a length of 60.

Answer 2

5 * 4 = 20 * 3(length of z)= 60

Answer 3

5*4*[1,2,3] it will create 60 elements in z(as it iterables)
SO the len gives 60
