name? 5. handle errorsFor error exception handling, try and retry T statements are mainly used. For example, modify gopherclient. py in python network programming learning Note (1: The code is as follows: #-*-Coding: cp936 -*-# Modify by xiaowuyiImport socket, sysPort = 70Host = sys. argv [1] Filename = sys. argv [2] Try:S = socket. socket (socket. AF_INET, socket. SOCK_STREAM)Failed T Socket. error, e:Print "socket creation error: % s" % e Try:S.

This article mainly introduces how python uses socket to send data to the client. it involves the techniques of using socket to implement data communication in Python, which is of great practical value, for more information, see the following example. Share it with you for your reference. The details are as follows: Import socket, sysport = 55555 host = 'localhost' data = "test" * 10485760 #40 MB of datas = socket. socket (socket. AF_INET, socket

Makefile functionPython file class objects can read and write directly, and so on, when using the socket to write services, the socket object can be used as a text object directly to read and write performance? The answer is yes, you can use the Makefile function to produce a file class object.Makefile function:Returns a socket associated file class object, makefile has two parameters: one for the file class mode, the other for the cached mode, the file class mode contains read-only, write-only

This example describes how Python uses the socket to send data to the client. Share to everyone for your reference. Specific as follows: Import socket, Sysport = 55555host = ' localhost ' data = ' Test ' * 10485760 # 40MB of datas = Socket.socket (socket.af_inet, S Ocket.
