A bit of socket code from python

Sockets are used nearly everywhere.This is a bit of socket code form python.This program is designed to test FRS4 socket communicate test as below.

import socket

print "-----------------------------------------------------------"
print "Welcom to use Python Socket Tools./nThis program is designed to test FRS4 socket communicate test/n----Powered by Lucker."
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)   #Create a socket
try:
    s.connect((socket.gethostname(),  8888))    #Connect to target server
except:
    print "Connect to '%s' failed!"%(socket.gethostname())
else:
    phoneno = raw_input("Please input your PhoneNo.:(Push Enter to use default)")   #Get local phoneno
    if (len(phoneno)) == 0:
        phoneno= '123456'
    phoneno="phone:"+phoneno    #Add a prefix of phoneno

    s.send(phoneno) #Send data string to server
    print '>> %s'%phoneno
    data = s.recv(4096) #Get response data from server
    print '<< %s'%data
    process_string='*571253*61235468*1*2617*5#'
    s.send(process_string)
    print '>> %s'%process_string
    print '<< %s'%s.recv(4096)
    s.send('6506')
    print '>> %s'%'6506'
    print '<< %s'%s.recv(4096)
    s.close()   #Disconnect the socket connection
print 'End!'    #End the program

Meybe,we need a special class for our communication in the socket program.We call it "MySocket" as below

class mysocket:
    '''demonstration class only coded for clarity, not efficiency '''
    def __init__(self, sock=None):
        if sock is None:
            self.sock = socket.socket( socket.AF_INET, socket.SOCK_STREAM)
        else:
            self.sock = sock
    def connect(self, host, port):
        self.sock.connect((host, port))
    def mysend(self, msg):
        totalsent = 0
        while totalsent < MSGLEN:
            sent = self.sock.send(msg[totalsent:])
            if sent == 0:
                raise RuntimeError,"socket connection broken"
            totalsent = totalsent + sent
    def myreceive(self):
        msg = ''
        while len(msg) < MSGLEN:
            chunk = self.sock.recv(MSGLEN-len(msg))
            if chunk == '':
                raise RuntimeError,"socket connection broken"
            msg = msg + chunk
        return msg
