Python TCP trying to send object a bytes-like object is required

Question

I'm trying to send a custom object via sockets in Python. My object is defined as:

packet = Packet.Packet(MAGIC_NUMBER,0,sender_next,packet_size,local_buffer)
port_out.send(packet)

But I am getting an error of: builtins.TypeError: a bytes-like object is required, not 'Packet'

I've seen previous posts about using .encode() for str types but how do I do it for a custom object like this? Do I need to make a encode method?

You need a way of converting to `bytes`. For strings that is `.encode()`. For your `Packet` object it's whatever you choose to call it. — Steven Rumbalski, Sep 04 '17 at 02:23

You can use pickle

import pickle

packet = Packet.Packet(MAGIC_NUMBER,0,sender_next,packet_size,local_buffer)
port_out.send(pickle.dumps(packet))
