What could be causing this error: RuntimeError('Event loop is closed') in Python

I am creating a discord bot in pyCharm. This is the following code I have:
# bot.py
import os
import discord
from dotenv import load_dotenv
load_dotenv()
TOKEN = os.getenv('DISCORD_TOKEN')
GUILD = os.getenv('DISCORD_GUILD')
client = discord.Client()
#client.event
async def on_ready():
for guild in client.guilds:
if guild.name == GUILD:
break
print(
f'{client.user} is connected to the following guild:\n'
f'{guild.name}(id: {guild.id})'
)
client.run(TOKEN)
When I run it the following errors are produced:

Now, what I find interesting is this:
I can assure you that I have a .env file set up as such:
DISCORD_TOKEN={my-token-here}
DISCORD_GUILD={my-server-here}
and it is the correct information
I know this because when I take the same token out of the .env file and just paste it directly into client.run() it works without issue, but of course this is private information!
So, the issue is that my file isnt being read properly? I would disagree because in testing I find that the string in DISCORD_GUILD is being read in properly without issue
I also tried the ole turn it off and back on trick by resetting to a new token but no luck
This is my last resort to understanding this error. Does anyone know what could be causing this error and ho to fix it?

Your .env file should look like this:
# .env
DISCORD_TOKEN = ADASIUHFOAka12312jsdfhpAFDA.GnTdIh.dOU0fjmz-WhfDebLN7x8ncuGbLVWyPXNftirGA
Should not contain the {}, if you included them (taking literally as you wrote in your question).
Also, you should set your intents under Discord Developers - Applications and declare them when defining client.

RuntimeError: Event loop is closed when connecting python discord bot

I just started writing a discord bot with python and although the code is very simple, I somehow keep getting a RuntimeError when trying to connect
I checked the token multiple times
would really appreciate it if someone could tell me what I did wrong
python Script:
import discord
from discord.ext import commands
bot = commands.Bot(command_prefix=':')
#bot.event
async def on_ready():
print('bot is ready')
bot.run('my_token')

You're using the wrong discord token. First of all, you leaked your bot token
bot.run('Bxb-8dRGeYHYLFD5-IXGhNfY1TnX3kKA')
Regenerate your toek ASAP. Second, make sure you grab the token in the Bot Tab, and you don't get any of the other tokens. I can tell that the token is too short and is the wrong token.

I'm pretty sure you're using the client secret code, which is not your bot's token. What you have to do is go to applications in Discord's Developer Portal. Once you're there, click on your bot application, and then go to the Bot tab on the left (it will have a little puzzle piece next to it). Over there, you should see Click to Reveal Token under Build-A-Bot. You can either click that and copy what shows up, or you can simply click the Copy button which will automatically copy the bot's token for you. Please do not share your token with anyone, as it can be used to run other people's code if they have access to it. If you've already leaked it, just go ahead and click the Regenerate button, which will give you a new token for your bot, and it will null the older token so that nobody can use your bot anymore.

Running telethon on pythonanywhere

try to run a basic scripts that adds members to a telegram group over pythoneverywhere server. I installed the main package which is telethon in the server. but i am getting the error in the image below. what am i not doing right?

Why am I getting "RuntimeError: This event loop is already running"

Im working on a slack bot using the new slack 2.0 python library. I am new to python decorators and I suspect that is part of my problem.
Here is my code...
#!/opt/rh/rh-python36/root/usr/bin/python
import os
import slack
# instantiate Slack client
slack_token = os.environ['SLACK_BOT_TOKEN']
rtmclient = slack.RTMClient(token=slack_token)
webclient = slack.WebClient(token=slack_token)
# get the id of my user
bot_id = webclient.auth_test()['user_id']
print('Bot ID: {0}'.format(bot_id))
def get_user_info(user_id):
user_info = webclient.users_info(user=user_id)['ok']
return user_info
#slack.RTMClient.run_on(event='message')
def parse_message(**payload):
data = payload['data']
user_id = data['user']
print(get_user_info(user_id))
rtmclient.start()
It outputs the Bot ID(using the webclient) when started but then crashes with RuntimeError: This event loop is already running when I make another call to webclient.
[root#slackbot-01 bin]# scl enable rh-python36 /root/slackbot/bin/slackbot.py

The really confusing part to me is that if I comment out the line that makes the first call to webclient.auth_test(), I have no issues at all. My call to webclient.users_info() works every time rtmclient sends me data.
#!/opt/rh/rh-python36/root/usr/bin/python
import os
import slack
# instantiate Slack client
slack_token = os.environ['SLACK_BOT_TOKEN']
rtmclient = slack.RTMClient(token=slack_token)
webclient = slack.WebClient(token=slack_token)
# get the id of my user
#bot_id = webclient.auth_test()['user_id']
#print('Bot ID: {0}'.format(bot_id))
def get_user_info(user_id):
user_info = webclient.users_info(user=user_id)['ok']
return user_info
#slack.RTMClient.run_on(event='message')
def parse_message(**payload):
data = payload['data']
user_id = data['user']
print(get_user_info(user_id))
rtmclient.start()
[root#slackbot-01 bin]# scl enable rh-python36 /root/slackbot/bin/slackbot.py
True
True
^C[root#slackbot-01 bin]#
I need to get the bot id so that I can make sure it doesnt answer it's own messages. I don't why my code doesnt work after I get the bot id outside of the parse message function with a decorator.
What am I doing wrong here?

The python event loop is a tricky thing to program libraries around and there are some issues with the way the event queue is managed in the 2.0 version of SlackClient. It looks like some improvements were made with 2.1 but it appears to be a work in progress, and I still encounter this. I'd expect there will be future updates to make it more robust.
In the meantime, the following code at the top of your file (use pip to install) usually resolves it for me:
import nest_asyncio
nest_asyncio.apply()
Keep in mind this will alter the way the rest of your application is handling the event queue, if that's a factor.

If you're using RTM, the RTMClient creates a WebClient for you. The handle for it should be getting passed to you in the payload when you handle an event. You can check your ID by looking for the 'open' event which is always dispatched after RTM successfully connects and doing the lookup inside your 'open' event handler.

Python3.5 Asyncio - Preventing task exception from dumping to stdout?

I have a textbased interface (asciimatics module) for my program that uses asyncio and discord.py module and occasionally when my wifi adapter goes down I get an exception like so:
Task exception was never retrieved
future: <Task finished coro=<WebSocketCommonProtocol.run() done, defined at /home/mike/.local/lib/python3.5/site-packages/websockets/protocol.py:428> exception=ConnectionResetError(104, 'Connection reset by peer')>

ConnectionResetError: [Errno 104] Connection reset by peer
This exception is non-fatal and the program is able to re-connect despite it - what I want to do is prevent this exception from dumping to stdout and mucking up my text interface.
I tried using ensure_future to handle it but it doesn't seem to work. Am I missing something:
#asyncio.coroutine
def handle_exception():
try:
yield from WebSocketCommonProtocol.run()
except Exception:
print("SocketException-Retrying")
asyncio.ensure_future(handle_exception())
#start discord client
client.run(token)

Task exception was never retrieved - is not actually exception propagated to stdout, but a log message that warns you that you never retrieved exception in one of your tasks. You can find details here.
I guess, most easy way to avoid this message in your case is to retrieve exception from task manually:
coro = WebSocketCommonProtocol.run() # you don't need any wrapper
task = asyncio.ensure_future(coro)
try:
#start discord client
client.run(token)
finally:
# retrieve exception if any:
if task.done() and not task.cancelled():
task.exception() # this doesn't raise anything, just mark exception retrieved

The answer provided by Mikhail is perfectly acceptable, but I realized it wouldn't work for me since the task that is raising the exception is buried deep in some module so trying to retrieve it's exception is kind've difficult. I found that instead if I simply set a custom exception handler for my asyncio loop (loop is created by the discord client):
def exception_handler(loop,context):
print("Caught the following exception")
print(context['message'])
client.loop.set_exception_handler(exception_handler)
client.run(token)
