'why can't I connect to server?

so I have just started learning network programming and I don't understand why does a connection between the client and the server is constantly denied.

import socket
my_socket = socket.socket()
my_socket.connect(("127.0.0.1", 8820))

that is the error I get:

ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

python sockets

A client program connects to a server program. A server program is a program which listens to a particular port and a client program connects to that port.

Your program tries to connect to your own computer, port 8820. If there isn't a program running on your computer which is listening to port 8820, there is nothing to connect to so you get a connection refused error.

"Connection refused" specifically means that your computer was able to access IP address 127.0.0.1, but at that IP address, there was no program listening to port 8820.
