how to do something like streams inside a port (Python socket)

there is such a code:

server:

import socket
from threading import Thread
from time import sleep

sock = socket.socket()

sock.bind(('', 1337))
sock.listen(1)
conn, addr = sock.accept()
def func1():
    while True:
        conn.send("1".encode("utf-8"))
        sleep(0.5)
def func2():
    while True:
        conn.send("2".encode("utf-8"))
        sleep(0.5)
t1 = Thread(target=func1)
t1.start()
t2 = Thread(target=func2)
t2.start()

client:

import socket
from threading import Thread
from time import sleep

sock = socket.socket()
sock.connect(('localhost', 1337))

def func1():
    while True:
        data = sock.recv(1024).decode("utf-8")
        if data != "1":
            print("the package did not arrive properly")
        else:
            print("package arrived ok")
def func2():
    while True:
        data = sock.recv(1024).decode("utf-8")
        if data != "2":
            print("the package did not arrive properly")
        else:
            print("package arrived ok")
t1 = Thread(target=func1)
t1.start()
t2 = Thread(target=func2)
t2.start()

you need to make sure that the packet sent by function1 comes to function1, and the packet of function2 comes to function2, but this code does not work correctly, and packets from function1 often end up in function2 and vice versa

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
