Send a packet of data literally via UDP in Python

Question

I want to my UDP data packet to have literately this information for example:

data = "83053163021478010102010370020000000000"

I'm using the follow code to send it which works fine(I can see it going out on wireshark):

listener = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
listener.sendto(data, (IP, PORT))

When I look at the data packet in wireshark i want the (wireshark)data packet == data. How do I declare/convert the data type to make this happen.

Do you mean that you want to convert the hexadecimal values in the data into raw binary? Otherwise I don't understand the question — hcs

data is a hex string represented as ascii string. I want listener.sendto(data, (IP, PORT)) to send data as the literal hex bytes that the data string equals — Nimjox

I think this should do the trick:

import codecs
data = codecs.decode("83053163021478010102010370020000000000", "hex_codec")

Then you can send data same as you are doing now.
