client and server sockets. To create a simple server with TCP and streaming sockets in Python, you need to use the socket module. Using the functions and class definitions contained in this module, you can generate programs that communicate over the network. In general, it takes six steps to establish a server connection.
The 1th step is to create a socket obje
Previously also learned the socket programming, this time want to systematically study the use of Python network programming. Do this, for testing progress, also leave notes and footprints for the follow-up.
Socket common functions get host name and host address

to receive information from the customer. When calling recv, the server must specify an integer that corresponds to the maximum amount of data that can be received through this method call. The Recv method enters the "blocked" state when it receives the data, and finally returns a string that represents the received data. If the amount of data sent exceeds the allowable recv, the data will be truncated. The excess data will be buffered on the receiving side. When Recv is called later, the extra
Prior to implementing the Java version of the TCP and UDP socket programming example, so decided to combine Python learning to do a python version of the socket programming experiment.The process is as follows:1. A client reads a

Socket is a method of inter-process communication. It communicates with other processes mainly in different ways: it can implement inter-process communication between different hosts, most of our various services on the network communicate based on sockets, such as Browsi
succeeds, the client can communicate with the server through the socket, and if the connection fails, a Socket.error exception is thrown.3. During the processing phase, the client and the server communicate via the Send method and the Recv method.4. When the transfer is complete, the client closes the connection by calling the Close method of the socket.server.pyImportSockets=socket.socket (socket.af_inet, socket
