Как отправить файл клиенту из filedialog с помощью программирования сокетов

Question

Я хочу отправить файл от одного клиента другому клиенту через сервер. Файл выбран из filedialog, в то же время я отправляю обычный текст, но я не могу понять, как мы это делаем с файлом?

Вот что у меня есть

Server.py

from socket import *
from threading import *
import socket
from tkinter import *
clients = set()

def clientThread(clientSocket, clientAddress):
    while True:
        message = clientSocket.recv(1024)
        print(clientAddress[0] + ":" + str(clientAddress[1]) +" says: "+ message)
        for client in clients:
            if client is not clientSocket:
                client.send((clientAddress[0] + ":" + str(clientAddress[1]) +" says: "+ message))

        if not message:
            clients.remove(clientSocket)
            print(clientAddress[0] + ":" + str(clientAddress[1]) +" disconnected")
            break

    clientSocket.close()

hostSocket = socket.socket(AF_INET, SOCK_STREAM)
host_name = socket.gethostname()
ip=socket.gethostbyname(host_name)
print (ip)
portNumber = 7500
hostSocket.bind((host_name, portNumber))
hostSocket.listen()
print ("Waiting for connection...")


while True:
    clientSocket, clientAddress = hostSocket.accept()
    clients.add(clientSocket)
    print ("Connection established with: ", clientAddress[0] + ":" + str(clientAddress[1]))
    thread = Thread(target=clientThread, args=(clientSocket, clientAddress, ))
    thread.start()

Client.py

from tkinter import *
from threading import *
from socket import *
from tkinter import filedialog

clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
portNumber = 7500

    def test1():

            print((EDIentry.get()))
            clientSocket.connect((EDIentry.get(), portNumber))
        else:
            print ('error')

    SCbutton.grid(column=1, row=4)

        txtMessages.insert(END, "\n" "client : " + clientMessage)
        clientSocket.send((clientMessage.encode("utf-8")))
        filedata=name.read()
        print (filedata)

    btnSendMessage = Button(root, text="Send", width=20, command=sendMessage)
    btnSendMessage.grid(row=2, column=0, padx=10, pady=10)

    def recvMessage():

            serverMessage = clientSocket.recv(1024).decode("utf-8")
            print(serverMessage)
            txtMessages.insert(END, "\n"+serverMessage)

    recvThread = Thread(target=recvMessage)

    recvThread.start()

def changepage():
    global pagenum, root
    for widget in root.winfo_children():
