How to Handle the `TypeError: a bytes-like object is required, not \'str\'` When Sending User Input Through a Socket in Python 3?

Encoding Byte-Like Objects to Address TypeError

When attempting to modify user input via socket communication, you may encounter the following error in Python 3:

TypeError: a bytes-like object is required, not 'str'

To resolve this issue, you need to encode the input message before sending it through the socket. Python 3 expects byte-like objects for network data transfer, not strings.

The corrected code should include the following adjustment:

clientSocket.sendto(message.encode(),(serverName, serverPort))

By encoding the message variable, you convert it into a byte-like object that can be transmitted over the network.

Similarly, on the server side, you should decode the received data before printing it to ensure it displays as intended:

modifiedMessage, serverAddress = clientSocket.recvfrom(2048)
print (modifiedMessage.decode())

This modification effectively addresses the TypeError and enables you to successfully transmit and modify user input through socket communication.
