UDP Chat in Python Using Socket

Here I will share a very basic UDP chat application in Python using sockets.

It can work in point-to-point or broadcast mode.

For Point-to-Point, enter IP and Port.

For Broadcasting mode set the last byte of IP address to 255. i.e.

Port number is HEX, remove the base 16 to make it decimal.
