My code:

    tron = Tron(full_node=full_node,
        solidity_node=solidity_node,
        event_server=event_server)
    print(tron.toSun(0.2))
    tron.private_key = pkey
    tron.default_address = tron.address.from_private_key(pkey).base58
    trx_kwargs = dict()
    trx_kwargs["private_key"] = pkey
    trx_kwargs["default_address"] = tron.address.from_private_key(pkey).base58
    tron = Tron(**trx_kwargs)
    kwargs = dict()

    kwargs["call_value"] = 10
    payment_amount = int(float(payment_amount))
    kwargs["parameters"] = [

    'value': tron.address.to_hex(payment_address)
    },
    {

    'value': payment_amount * 1000000 
    }
    ]

    raw_tx = tron.transaction_builder.trigger_smart_contract(**kwargs)
    print(raw_tx)
    print("++++++++++++++++++")
    signed = tron.trx.sign(raw_tx["transaction"])
    print(f"\n\nSENDING {payment_amount} USDT TO {payment_address} IN 2 SEC...\n")
    time.sleep(2)
    result = tron.trx.broadcast(signed)

    print("RESULT", result, "\n\n")
    return result

please tell me what I'm doing wrong. how do I fix my code?
