I'm a little confused by for A in range(1, 27): for B in range(1, 27): if A == 2 * B: Why iterate over anything here? for A in ra

I'm a little confused by for A in range(1, 27): for B in range(1, 27): if A == 2 * B: Why iterate over anything here? for A in range(1, 27): if A % 2 == 0: B = A / 2 Or for A in range(2, 27, 2): B = A / 2 Is there a full version of the naive nested loops? I'd like to see just how readable the final version is with applying more rules like this.
