How to get a person by ID discord.py?

Question

Python

Hello, I need to get a person by ID, which is not a member of the bot's discord servers.
And send him a message

Answer 1

1. Client.fetch_user
2. None. Bots cannot write to users they cannot see.

Answer 2

It’s interesting to me that the bot wrote to an account that I just created and he already wrote to me, it’s a pity that so far I won’t find the answer to this question
