[FIXED] global variable not defined inside async function

Issue

I have an async function that is supposed to add reactions to a list until a certain reaction is pressed then it will add all appropriate roles. to do this I have a global variable "reactions = []" that gets reset when the "ok" reaction is pressed. VS Code is telling me this on the line "for react in reactions:" : "reactions is used before it is defined. Move the definition before." this is confusing because roleEmojis is another global variable but that works fine. here is my code:

import os
import discord
import time
from discord.utils import get
from discord.ext import commands

token = "TOKEN"
BOT = commands.Bot("£")
reactions_list = []

@BOT.event
async def on_reaction_add(reaction , user):
    if reaction.emoji in roleEmojis.keys() and user != BOT.user:
        if reaction == get(reaction.message.guild.emojis, name = "OK"):
            for react in reactions_list:
                await user.add_roles(roleEmojis[react.emoji])
            reactions_list = []
        else:
            reactions_list.append(reaction)

BOT.run(token)

Side note: I haven't yet figured out how to detect when someone has "un-reacted" to a message, id appreciate any help there

Solution

use global reactions in your local method to make use of global variable

And as per the error you mentioned your error lies in for loop which I cant see in code snipped. In python you need to explicitly mentioned if you're using global variable. (except if it is a list and your using that through function parameter or any other data type which uses address).

Ex-

a=0
def b():
    a=1
b()
print(a)

Will result 0

a=0
def b():
    global a
    a=1
b()
print(a)

will result 1
