I am currently using the pysher python package as basis for my pusher client with python 3.5.
Based on my experiences pysher is currently not capable to recover from pusher errors or temporary interruptions of the internet connection, resulting in loss of pusher notifications. Also the performance requirement (CPU usage and memory) is too high, resulting in the need to kill and restart the pusher clients every now and then.
I would therefore like to implement a python 3.5 based pusher client in an alternative way (without the pysher package). As I have heard asyncio would be very suitable for this use case, I would like to consider this too.
How can I implement this?
Thanks!

I'm trying to communicate with an ESP32 microcontroller and my linux desktop using Bluetooth Low Energy.
Right now I'm using the notification example from https://pypi.org/project/pygatt/ (carefully replacing the MAC address and UUID of course).
The pygatt library runs gatttool under the hood, and is pretty flaky. Sometimes the example reports a single value before the program terminates. Sometimes it reports a spate of values and then hangs.
I was wondering if there were any alternatives to pygatt that were more robust?
gatttool is one of the eight tools that BlueZ deprecated.
BlueZ publishes an API using D-Bus and there are various D-Bus bindings for Python
For a BLE client you will need the following API parts of BlueZ:

https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/device-api.txt
https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/gatt-api.txt
An example of how to do this with pydbus is at:

There are also a number of other BLE Python libraries available on PyPI but not all of them built using the BlueZ supported D-Bus API.

I am trying to implement a p2p application. I want to use DHT in libtorrent library. I would like to use python for p2p application. Can anyone suggest an example dht libtorrent python implementation or some api that I can use?
Deluge is well supported implementation of libtorrent in python which supports DHT
Also DHT is enabled by default in libtorrent, even in the python bindings.

I have written an application in python 2.7. Now I have to add a feature in it, in which it will find the list of DMRs available in the network and then user will select the device from the list and send data from the application to the device.
For this I searched on google for python upnp libraries, and I got these (coherence, miranda-upnp, miniupnp, pyunpnp).
I also read about them, but i couldn't figure out which library i should use.
Tell me which library I should use and why ?
MiniUPnPc is actively supported (I'm the maintainer), it is a C library but there is a python module. Here is a good example for how to use it : https://github.com/miniupnp/miniupnp/blob/master/miniupnpc/testupnpigd.py
But you would prefer miranda-upnp if you want to use a 100% python library.

I am looking for an open source monitoring solution (preferably in Python) that works with ssh or snmp and does not require the installation of an agent (like Nagios, ZenOSS, munin).
Are you aware of such a solution?
All tools that allow you to run scripts to gather metrics can basically run commands over a ssh connection on the target box.
The question is though if this makes a lot of sense as you rely on the network connection always being available and for each (set of) property(s) you need to run a new remote connection with all its overhead.
Snmp does by definition of the protocol require you to run an snmp agent on the target box.

What is the recommended library for python to do everything that is Amazon EC2 related?
I came across boto and libcloud. Which one is easier to use? does libcloud offer the same functionality as boto?
The big advantage of libcloud is that it provides a unified interface to multiple providers, which is a big plus in my mind. You won't have to rewrite everything if you plan to migrate some instances to Rackspace later, or mix and match, etc. I haven't used it extensively but it looks fairly complete as far as EC2 goes. In boto's favor it has support for nearly all of Amazon's web services, so if you plan to be Amazon-centric and use other services you'll probably want to use boto.
That said, try both packages and see which you prefer.
