brother you have put the ip as localhost in both computers

localhost means the ip of the computer you are writing the code in,

to connect, enter the server's ip , the client's ip does not matter at all in the client's code

also specify this: socket=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

note: SOCK_STREAM is for tcp, SOCK_DGRAM is for udp

that's why when you tried it in one computer , the client ip was the same as server ip as localhost gives the current computer's ip

IF YOU WANT TO KNOW THE SERVER'S IP , TYPE ipconfig IN CMD PROMPT AND COPY THE WLAN IP, DO NOT COPY VIRTUAL BOX ETHERNET IP , YOU CAN ALSO COPY THE WIFI IP

I am young(14) but I know this well

please ask again if any doubt brother/sister
