Discord.py private messages by id?

Question

Python

There is a discord server and it has a bot written in python.
It is necessary that the bot send a private message to the admin when entering the command.

async def test(ctx):
    await ctx.author.send('test')

how to do the same with only user id?
And is it even possible?

async def test(ctx):
   await ctx.idadmin.send('test')

Answer 1

The code is not written correctly, read the discord.py documentation
Link: https://discordpy.readthedocs.io/en/latest/api.html
code that can function:

async def test(ctx, *, user_id: int):
    user = await Client.fetch_user(user_id=user_id)
    await user.send('test')
