How to send a message to a chat by chat ID - discord.py rewrite?

Question

Python

Hello, here I have a code by which messages should be sent to the channel indicated in the message:

@bot.command()
async def news(ctx,channel_id, text):
    emb= discord.Embed(title='Новость!!!',description=f'{text}', timestamp=ctx.message.created_at)
    channel= bot.get_channel(channel_id)
    await channel.send(embed=emb)

I wrote on one of your questions, but it gives an error:

Ignoring exception in command news:

And if you write:

@bot.command()
async def news(ctx,channel_id, text):
    emb= discord.Embed(title='Новость!!!',description=f'{text}', timestamp=ctx.message.created_at)
    channel= bot.get_channel(channel_id)
    await ctx.channel.send(embed=emb)

That will be sent to the same channel in which the command was written

. Is it possible to write something to a friend?

Answer 1

bot.get_channelaccepts an ID in the int type as an argument. By default, all arguments passed to the command by the parser are passed there as str, unless another type is specified. In your case, this function will never return a channel.
The most adequate solution in the context of discord.py: Use converters .

@bot.command()
async def news(ctx, channel: discord.TextChannel, *, text):  # используем kwargs для отсутствия необходимости написания ковычек: https://discordpy.readthedocs.io/en/stable/ext/commands/commands.html#keyword-only-arguments
    emb= discord.Embed(title='Новость!!!',description=f'{text}', timestamp=ctx.message.created_at)
    await channel.send(embed=emb)

This will allow you to get a channel in a team not only by ID, but also by its mention or just by name.
