Tell us what’s happening:

Describe your issue in detail here.i do not understand
it said i should reduce the indentation after the return statement

/* User Editable Region */

A = list(range(NUMBER_OF_DISKS, 0, -1))

        # move n - 1 disks from source to auxiliary, so they are out of the way
        move(n - 1, source, target, auxiliary)
        # move the nth disk from source to target
        # display our progress
        print(A, B, C, '\n')
        # move the n - 1 disks that we left on auxiliary onto target
        move(n - 1,  auxiliary, source, target)      
# initiate call from source A to target C with auxiliary B
