How do I get the username of a member of a discord server from their user id

Question

I've been looking through the docs, and I found the get_members function, but when I used this function and I try to get the name or nick or nickname field, it returns an error saying that the attribute doesn't exist. Here's my code:

embed = discord.Embed(title=ctx.message.server.get_member(row[0]).nickname,  color=embedColor)

Here's the error:

'NoneType' object has no attribute 'nickname'

Answer 1

row[0] was, in fact, not a string. And the attribute I was actually looking for was "name."
