why does server and client code keep having this error?

Question

I've just finish coding my chat application using socket import on python and i came across with a error "OSError: [WinError 10038] An operation was attempted on something that is not a socket"

I never came across this error and I don't know what to do

in previous codes that was almost exactly like this one an error from this kind never popped up

can someone help me out, it will be much appreciated.

thank you
