I have been learning Python for a long time, but I have never felt any obvious indication. After thinking about it recently, I still feel that my goal is not clear enough. I don't know what I can do after learning it (for amateurs, learning programming is a hobby). So I am reading everything, but nothing works. Finally, let's take a look at network

Python has been learning for a long time, but it has never felt obvious. Recently think about, or feel that their goals are not clear enough, not clear what can be done after learning (amateur, learning programming is a hobby), so everything is looking at, but nothing has become. Summed up the next, to determine in the network

After reading this section, I suddenly got to know some incomprehension issues in the python network programming learning Notes (1). at least I understood what happened to socket. Here, we will not take notes on the origin of socket and directly go to the topic. 1. create a socket To create a socket object, you must understand the communication type and protocol

Based on the understanding of the basic syntax of Python, it is possible to freely assemble a variety of advanced functions that you need.Because of the characteristics of Python language, the implementation of various functions will be very fast.The network becomes one of the advanced features that Python has. Need to

arrival, reliability and data repeatability can not be guaranteed. The datagram preserves the data boundaries, which means that the data is not split into small chunks like a connection-oriented protocol.The primary protocol for implementing this connection is the User Datagram Protocol (that is, UDP). To create a UDP socket, you specify that the socket type is SOCK_DGRAM when it is created. Because these sockets use Internet protocols to find hosts in the
