def hanoi(num_disks, from_rod, to_rod, aux_rod): # Correct the base case if num_disks >= 0: # Correct the calls

The code seems to be correct. It implements the recursive solution to the Tower of Hanoi problem. The base case is when there are no disks left to move, and in that case, the function simply returns without doing anything. Otherwise, it calls itself recursively to move all but the bottom disk from the source rod to the auxiliary rod, then it prints a message to indicate that it's moving the bottom disk from the source rod to the target rod, and finally, it calls itself recursively again to move all the disks from the auxiliary rod to the target rod.
