今天小编就为大家分享一篇关于Python一个简单的通信程序(客户端服务器)，小编觉得内容挺不错的，现在分享给大家，具有很好的参考价值，需要的朋友一起跟随小编来看看吧

功能是从客户端向服务发送一个字符串, 服务器收到后将字符串重新发送给客户端,同时,在连接建立之后,服务器可以向客户端发送任意多的字符串

客户端:

10.248.27.23是我电脑的IP

				?

									import socket, sys

									host = '10.248.27.23'

									# host = raw_input("Plz imput destination IP:")

									# data = raw_input("Plz imput what you want to submit:")

									port = 51423

									s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

									try:

									  s.connect((host, port))

									except socket.gaierror, e:

									  print "Address-related error connecting to server: %s" %e

									  sys.exit(1)

									except socket.error, e:

									  print "Connection error: %s" %e

									  sys.exit(1)

									data = raw_input("Plz imput what you want to submit:")

									s.send(data)

									s.shutdown(1)

									print "Submit Complete"

									while 1:

									    buf = s.recv(1024)

									    sys.stdout.write(buf)

服务器:

				?

									import socket, traceback

									host = ''

									port = 51423

									s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

									s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

									s.bind((host, port))

									s.listen(1)

									print "done"

									while 1:

									  #when connect error happen, skip the error

									  try:

									    ClientSock, ClientAddr = s.accept()

									  except KeyboardInterrupt:

									    raise

									  except:

									    traceback.print_exc()

									    continue

									  #Get informaion form client and reply

									  try:

									    print "Get connect from ", ClientSock.getpeername()

									    data = ClientSock.recv(1024)

									    print "The information we get is %s" % str(data)

									    ClientSock.sendall("I`ve got the information: ")

									    ClientSock.sendall(data)

									    while 1:

									      str = raw_input("What you want to say:")

									      ClientSock.sendall(str)

									      ClientSock.sendall('\n')

									  except (KeyboardInterrupt ,SystemError):

									    raise

									  except:

									    traceback.print_exc()

									  #Clocs socket

									  try:

									    ClientSock.close()

									  except KeyboardInterrupt:

									    raise

									  except:

									    traceback.print_exc()
