 Here we have used list comprehensions couple of times. *[int(x) for x in input("").split(" ")]* here first it takes the input as string by *input()*, then split the result by " ", then for each value create one int. We are also using *[a[i][j] * b[j][i] for j in range(0,n)]* to get the resultant row in a single line.
