title: How to change nickname (discord.py)
body: <p>I want to make a command that changes a nickname to a specific user (Let it be Example # 1234). This command accepts an argument in which a new nickname must be entered, to which the old nickname must be changed - g!Chnick "ExampleNick". I do not know how to change the nickname to users of the Discord server, I tried it through the Guild class, I tried it through the Member class.
