In order to get the losses of the transformer you can sum the incoming flows like this:

bus_number = [3000, 3112, 3201]
ickt = "1"

flows = []
for i in range(3):
    ierr, flow = psspy.wnddt2(
        bus_number[i % 3],
        bus_number[(i + 1) % 3],
        bus_number[(i + 2) % 3],
        ickt,
        "FLOW"
    )
    flows.append(flow)

losses = sum(flows)

If you want the losses of an specific winding, the subsystem data retrieval API has the function awndreal with the string "PLOSS" and "QLOSS". Finally, the function awndint and awndchar can help you to make a tabular data structure.
