How to optimize discord bot in python?

Question

Python

Help optimize the bot. When 2 or more users click on an emoji, they are given a role, everything works fine here. But when they go through the channels with this role, the bot breaks down and removes and gives out roles with a huge delay. Help optimize.

Answer 1

Delete all roles at once, why one by one

if after.channel:
        await member.remove_roles(etaj1, etaj2, etaj3, ...)

Well, I would not immediately make 20 requests to get all the roles, if the condition is met before.channel, then it does not use any of the 10 variables that took time to create.
Well, it would be nice to use elif in the if construct, so as not to check conditions a hundred times that will definitely not be fulfilled.
