The preceding site confirmed an illustration of how to write down a consumer method that interacts with an existing server through a Socket item. This web site shows you the way to put in writing a method that implements another aspect with the relationship—a server software.

During the portion Information Entry Place, you acquired how the concept object was called into motion when socket gatherings ended up All set through .process_events(). Now you’ll understand what takes place right after info is study and written on the socket in addition to a concept is ready to be processed via the customer.
