create a udp client in python

To create a UDP Client in Python, we can use Python's socket module. Below is a simple example:


main.py
import socket

UDP_IP = "127.0.0.1"  # IP address of the server
UDP_PORT = 5005  # Port number of the server
MESSAGE = b"Hello, Server!"  # Message to be sent to the server

# create a UDP socket
sock = socket.socket(socket.AF_INET,  # Internet
                     socket.SOCK_DGRAM)  # UDP

# send the message to the server
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))

# receive the response from the server
data, addr = sock.recvfrom(1024)  # buffer size is 1024 bytes
print(f"Received message: {data.decode()}")
513 chars
17 lines

In this example, we first create a UDP socket using the socket() function and specifying that we want an Internet socket (AF_INET) that uses the UDP protocol (SOCK_DGRAM).

We then send a message to the server using the sendto() function and passing in the message and the server's IP address and port number.

Finally, we receive the response from the server using the recvfrom() function and print the received message.
