我不知道如何使用套接字库在多台电脑上进行聊天。我唯一尝试的就是用 radmin 的外部 IP 替换该 IP，并将程序提供给连接到网络的朋友，但这没有帮助，并且终端中出现错误，指示缺少服务器。

服务器：

import socket

HOST = "26.104.62.185"
PORT = 50000

server = socket.socket()
server.bind((HOST, PORT))
server.listen()

print("Сервер запущен!")
name = input("Введите ваше имя: ")
conn, addr = server.accept()

data = (conn.recv(2 ** 10)).decode()
print(f"{data} присоединился")
conn.send(name.encode())

while True:
    msg = input("Я: ")
    conn.send(msg.encode())
    msg = conn.recv(2 ** 10)
    msg = msg.decode()
    print(data, ":", msg)

客户：

import socket

HOST = "26.104.62.185"
PORT = 50000

server = socket.socket()

name = input("Введите ваше имя: ")
server.connect((HOST, PORT))
server.send(name.encode())
data = server.recv(2 ** 10)
server_name = data.decode()
print(f"{server_name} присоединился")

while True:
    msg = (server.recv(2 ** 10)).decode()
    print(f"{server_name}: {msg}")
    msg = input("Я: ")
    server.send(msg.encode())

需要做什么？

我创建了第二个窗口，当我尝试将对象添加到第二个窗口时，它们会添加到第一个窗口。需要做什么？

代码：

import tkinter as ttk
from tkinter import *
from tkinter import messagebox as msgbox


class AddWin(ttk.Toplevel):
    def __init__(self, parent):
        super().__init__(parent)

        # All elements
        lbl = ttk.Label(text="TEST")
        horizontal_scale = ttk.Scale(orient=HORIZONTAL, length=200, from_=1.0, to=100.0)

        # Start settings
        self.geometry("200x50")
        self.title("Sets MMC")
        self.resizable(True, True)
        self.protocol("WM_DELETE_WINDOW", self.closing_win)

        # Place elements
        lbl.pack()
        horizontal_scale.pack()

    def closing_win(self):
        if msgbox.askokcancel("Quit", "Do you want to save settings?"):
            pass    # Here's need be save settings

        self.destroy()


class App(ttk.Tk):
    def __init__(self):
        super().__init__()

        # All elements
        btn = ttk.Button(text="OFF", command=lambda: print("I WORK"))

        text_lbl = f"0p (pixels)"
        lbl = ttk.Label(text=text_lbl)

        sets_btn = ttk.Button(text="Settings", command=self.open_window)

        # Start settings
        self.geometry("200x75")
        self.title("MMC")
        self.resizable(True, True)
        self.protocol("WM_DELETE_WINDOW", self.closing_app)

        # Place elements
        btn.pack()
        lbl.pack()
        sets_btn.pack()

    def closing_app(self):
        if msgbox.askokcancel("Quit", "Do you want to quit?"):
            self.destroy()

    def open_window(self):
        add_win = AddWin(self)
        add_win.grab_set()


if __name__ == "__main__":
    app = App()
    app.mainloop()
