I have two files, one of which sets up the UDP Server and one of which sets up the UDP Client that the server should receive from.

When I start up the UDP Server file, it does what it is supposed to, which is display "the server is ready to receive" while the server is up.

However, whenever I run the client file and enter text to test the implementation, I get the following error:
gaierror: [Errno 11001] getaddrinfo failed

It is important to note that I am using Spyder (Anaconda Navigator) for Python 3.7. My questions are:

1. Is it possible to do this in Spyder?


2. If 1. is true, what am I doing wrong?

I've tried running the UDP Server file in the Windows Command Prompt and then tried to run the UDP Client file in order to see if the fact that I was running the server from Spyder affected the outcome, however I still got the same error saying "gaierror: [Errno 11001] getaddrinfo failed"

I've tried putting "socket.getaddrinfo('hostname', 12000)" into the Client File directly below the two definitions of the serverName and serverPort but this didn't work either

The code for the client is the first block of code, the code for the server is the second

import socket

serverName='hostname'
serverPort=12000
clientSocket=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
message= input('Input lowercase sentence:')
clientSocket.sendto(message.encode(),(serverName, serverPort))
modifiedMessage, serverAddress=socket.clientSocket.recvfrom(2048)
print(modifiedMessage)
clientSocket.close()

import socket

serverPort=12000
serverSocket=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
serverSocket.bind(("",serverPort))
print ("The server is ready to receive")
while 1:
 message, clientAddress = serverSocket.recvfrom(2048)
 modifiedMessage = message.upper()
 serverSocket.sendto(modifiedMessage, clientAddress)

Expected results:
Server takes in an all-lowercase sentence from the Client such as "hi there my name jeff" and then makes this sentence "HI THERE MY NAME JEFF"

Actual: Upon inputting the sentence, I get the following error message: "gaierror: [Errno 11001] getaddrinfo failed"
