I want a python script to execute on startup, so for that, I created a bat file and a vbs file
and it works when there is internet but most of the time when I turn on the pc and log in, the script launches before the pc connects to the internet and it gives me this error:

I made a Discord Bot using Python 3.6. It runs and behaves perfectly when run on my computer, yet when I run it on PythonAnywhere, I get this message. I installed Discord.py and all necessary modules. Please help. I am not that very good with complex programming talk, and not at all good with web talk, so please answer as simply as you can. Does this issue only happen with PythonAnywhere or all remote hosting sites?

This is because PythonAnywhere requires a proxy in such a way that the aiohttp websockets don't support. There's a thread on their forums about it here: https://www.pythonanywhere.com/forums/topic/7384/ (See #Patrick Haugh's comment above)
I'am trying to send task from django local app too remote rabbitmq server (preprod through vpn) but when I'm trying to send it always same error occure. Two errors code are related [Errno -9] Address family for hostname not supported and [Errno 111] Connection refused. The port 5672 is open the user is not the default user and the broker url is amqp://dist:dist#amqp.nopow-link.com:5672.
If someone can help me to understand what I'm doing wrong.

I have a server built in python, using Tornado and RethinkDB. Its been running for a long time, opening several connections to the DB per user. I never had any major problems by leaving them open -never closing them-. But checking out the log file I found out there's a lot of this warnings:

Should I worry about it? In that case, what are the good practices?
Yes, you need to close the connection to avoid connection leaks. This Flask example, from RethinkDB, does it:
https://github.com/rethinkdb/rethinkdb-example-flask-backbone-todo/blob/master/todo.py#L47-L65
Even if RethinkDB does not enforce a hard limit on number of connections (I'm not sure if it does or not), you can run into the limits of the OS.
My environment is Mac OS 10.9.2, python3.3, redis-2.6.9 (64-bit).
I have many threads (nealy 2000) that use the same redis instance to write data, but some threads throw the following exceptions:

Is there some way to solve this problem?
I tried to connect to redis server when this exception happens and use ulimit -n to set a larger number, but the two methods don't work.
I know why this happened. It's caused by the max number of connections to redis-server and it's related to the max number of file handlers that the OS sets.
If I set:
$ ulimit -n 1024
it works.
Most likely the reds server is not running. Run it using "redis-server" command.
brew services start redis (on mac)
I also faced this issue.
When you are using the wrong Redis HOST then you also meet that error.
