Is correct this modification for work in a raspberry Pi?

[nucklearproject]

Hi, I use my raspberry Pi B+ for sending data for serial UART port. TX pin

uart = serial.Serial(port='/dev/ttyAMA0', baudrate=31250)

midi = adafruit_midi.MIDI(midi_out= uart, out_channel=0, debug=True)`

But this error appear:

 File "/home/raspbi/.local/lib/python3.9/site-packages/adafruit_midi/__init__.py", line 171, in _send
    self._midi_out.write(packet, num)

TypeError: write() takes 2 positional arguments but 3 were given`

Work fine if delete 'num' argument..

Change this

def _send(self, packet, num):
        if self._debug:
            print("Sending: ", [hex(i) for i in packet[:num]])
        self._midi_out.write(packet, num)

To

def _send(self, packet, num):
        if self._debug:
            print("Sending: ", [hex(i) for i in packet[:num]])
        self._midi_out.write(packet)

It is correct?
