send a binary message to a udp server in python

To send a binary message to a UDP server in Python, you can use the socket module. Here's an example code snippet that demonstrates how to do this:

main.py
import socket

# create a socket object
client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# specify the server's IP address and port number
server_address = ('localhost', 12345)

# create the binary message
message = bytes([0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x21])

# send the message to the server
client_socket.sendto(message, server_address)

# close the socket
client_socket.close()
399 chars
17 lines

In this example, we create a UDP socket object and specify the server's IP address and port number. Then, we create a binary message using the bytes function and send it to the server using the sendto method of the socket object. Finally, we close the socket using the close method.

Note that in this example, the binary message is created manually using a list of integers in hexadecimal notation. However, you can create binary messages from strings or other data types using the appropriate functions in Python, such as struct.pack.
