client.connect("test.mosquitto.org", 1883)

client.loop_forever()

Hey, I'm trying to receive messages from the topic "medir" and put some conditions to send other messages to the topic "Valve_OC". the thing is that I want to receive all messages from the topic like in loop, but after receiving the first message the client disconnect. I have put the line client.disconnect() in each "if" because if I don't put it the client send me messages from the topic "valve_OC" I don't know why. any help?

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 ...
