Two clients do not connect to the server

I want to add a feature in which two clients can send messages to each other without stopping and without having to wait.

I have a server script:

import socket
import threading
from datetime import datetime
from random import randint

global num
num = 0

class serverThread(threading.Thread):
    def __init__(self, client, address):
        global num
        num = num + 1
        self.id = num
        threading.Thread.__init__(self)
        self.client = client
        self.address = address
        print "serverThread init finished-" + str(self.id)

    def run(self):
        print "r1 num-" + str(self.id)
        size = 1024
        while True:
            #try:
                print "r2*************-" + str(self.id)
                data = self.client.recv(size)
                print "r3..... " + data
                print "r4-" + str(self.id)
                if data:
                    print "r5-" + str(self.id)
                    response = data

                    self.client.send(response)
                    print "r6-" + str(self.id)
                else:
                    print "r7-" + str(self.id)
                    raise Exception('Client disconnected-' + str(self.id) )
            #except:
               # print "Except"
               # self.client.close()
               # return

def create(ipHost, port):
    server = socket.socket()
    server.bind((ipHost, port))
    print "The server was created successfully."
    return server

def listen(server):
    server.listen(5)
    client, address = server.accept()
    c1 = serverThread(client, address)
    c1.start()
    client, address = server.accept()
    c2 = serverThread(client, address)
    c2.start()
    print "finished both threads created"

    while c1.isAlive() and c2.isAlive():
        continue

server = create("0.0.0.0", 1725)
listen(server)

As you can see, I do not use tryand exceptbecause I do not know how to use them.

My second script, the client:

import socket
import threading

class sendThread(threading.Thread):
    def __init__(self, ip, port):
        threading.Thread.__init__(self)
        self.client = socket.socket()
        self.port = port
        self.ip = ip
        self.client.connect((self.ip, self.port))
        print "[+] New send thread started for "+ip+":"+str(port) + "...Everything went successful!"

    def run(self):
        while True:
            data = raw_input("Enter command:")
            self.client.send("Client sent: " + data)

class receiveThread(threading.Thread):
    def __init__(self, ip, port):
        threading.Thread.__init__(self)
        self.client = socket.socket()
        self.ip = ip
        self.port = port
        self.client.connect((str(self.ip), self.port))
        print "[+] New receive thread started for "+ip+":"+str(port) + "...Everything went successful!"

    def run(self):
        print "Entered run method"
        size = 1024
        while True:
            data = self.client.recv(size)
            if data != "" or data:
                print "A client sent " + data
def client():
    port = 1725
    ip = '127.0.0.1'
    print "Connection from : "+ip+":"+str(port)

    receive = receiveThread(ip, port)
    print "b1"
    receive.start()
    print "b2"
    send = sendThread(ip, port)
    print "b3"
    send.start()
    while send.isAlive() and receive.isAlive():
        continue
    print "-----END of While TRUE------"
    print "Client disconnected..."

client()

I thought it would be nice to describe my scripts step by step in my code, maybe this will help, so it will be more readable.

Problem

When I want to start the server before starting two clients, it prints

The server was created successfully.

I start 2 clients and both clients print:

Connection from : 127.0.0.1:1720
[+] New receive thread started for 127.0.0.1:1720...Everything went successful!
b1
Entered run method
b2
[+] New send thread started for 127.0.0.1:1720...Everything went successful!
b3
Enter command:

However, there is a problem second . , , , , . , , . , .
