I'm trying to build a notification system that would be triggered initially from an api call made on the cloud, and should trigger a notification on one of my agents' pc (assuming running windows 10)
I'd like to do that in python as this is my knowledge
How should I structure this ?
The hardest part I can't figure out and couldn't find anything online is how to link the "local" pc to the "server"/cloud system (i'm using aws if that is useful) which would store the notification and dispatch them for each one of my agent.
My ultimate goal is to use a phone solution like aircall and to show the contact name of the caller through a notification popup in windows (aircall does offer that natively but can't access my contact datrabase so i'm trying to override the same function of displaying the caller name)
any help or suggesiton appreciated
One solution could be to build a simple ElectronJS frontend app that runs on your agents' computer AND a Python web server that listens to Aircall's Webhook events.
The web server would listen to call.ringing_on_agent Webhook events sent from Aircall and send a WebSocket push event (using Pusher for example) to your ElectronJS app.
The ElectronJS app installed by your agents would listen to WebSockets from your Python web server and would trigger a native Windows notification with the information you want (check the doc here).

I am trying to create a python program that takes input of what homework assignments I have and stores all of that information so that I can send a notification to my phone when assignments are coming up. I want to be able to give input from my phone throughout the day and cant seem to find a way to interact with my script on my computer from my phone. Any ideas? Ps: if you know a way that I can send notifications to my phone that would also be cool.
It looks like you should create a classic client/server architecture. This is quite a big task. Your program running on your Windows computer acts as a server waiting for client (mobile application) requests. I propose to create a widely used REST API service using e.g. the Flask framework (server side) and use the Retrofit framework for the Android application.
Remember that when using the application on the Internet, you will have to ensure the availability of the server.
To send notifications from the server to the app, use Firebase Cloud Messaging
What I am trying to do is a quite basic task: to send event triggers from different services to Raspberry pi and do some tasks when these triggers are received, in other words to make "home automation".
I searched for many websites and links but all projects about ifttt and raspberry pi do the reverse job: raspberry pi posts a web request and another service receives this trigger and does something.
There are some projects to receive requests from google assistant on raspberry pi but google assistant posts a request which contains https://raspberry_ip_address:port/bla_bla which works locally, but I want to send request from my phone even if it is not connected to my home wi-fi.
I found that ProtaOS on rpi works for these tasks and there are some projects with node-red but I don't want to use both of these solutions, I want to write python code on my own.
Is there any api or library for getting requests from maker ifttt trigger events for Python?
Any help would be appreciated. Thanks!
If i understood your question correctly, You want to trigger something with your phone and then on raspi you will excecute something with that trigger generated from phone or any other device.
One way of doing this is to use an external api like thinkspeak or ifttt, for that you have to continiously read a particular field which your trigger will change
check this
Another way can be making your own api and using it both from your services to post data and your raspi to read data. Python Flask ia a very simple framework for building web api. For hosting there are many free services like heroku, pythonanywhere.
Flask 101 and Free Hosting!!!
Another way is to host your trigger listener in your raspi and port forward your raspi IP with Ngrok or any other services of such kind.Ngrok

There are a number of solutions I use in this scenario, depending on what the problem is and how frequently I need to push requests to the Pi. Here is my portfolio:
Get a 3G module like SIM900: https://www.amazon.co.uk/Aihasd-Quad-Band-Development-Wireless-Raspberry/dp/B01IBGDDVM/. This will allow you to receive SMS in real time and receive instructions with a push from your phone. I like this option for remote sensing and homes with a weak or unstable internet connection.
continuous calls to a server to check for updates (a method you sound familiar with). This works well if Wifi is good and data is cheap.
Web sockets: this allows a continuous connection to be kept open between Raspberry Pi and server, though it requires a stable and continuous connection. https://www.jaredwolff.com/raspberry-pi-getting-interactive-with-your-server-using-websockets/
I am trying to do some automations using Google Assistant. Is it possible to integrate the mobile google assistant app with python? For example if I say open edge in my PC in my mobile and I am able to fetch the same from a python app running on my PC, I can create custom actions based on that. Can anyone help me with how can that be possible?
At the highest level, Google Assistant is able to be programmed using "Actions on Google". Actions on Google takes your audio input and drives a service called "Dialog Flow". Dialog Flow parses your natural language looking for an "intent" (what you are asking for). When an intent is matched, a "Webhook" can be called to process the request.
If you have an application running on your Windows PC that is listening for an incoming REST request and can process the payload content, then the Webhook specified in Dialog Flow can be used to invoke your Windows application (REST app) that can perform the work.
Wiring all this up does take some skills. Some good reading to start with would be:

I have created a simple POS application. I now have to send a command to the receipt printer to print the receipt. I don't have any code related to this problem as I don't know where to start even. My questions are:
1) Is Windows a good choice for working with receipt printers as every shop I went to use a desktop application on Windows for POS?
2) Is it possible to control the receipt printer and cash register/drawer from a web app?
3) Is there a good reading material for developing POS systems by myself?
For a web app to use a device on the client, it has to go through the browser. I may be wrong, but I seriously doubt this is a built-in feature for receipt printers. I see three options:
1) Find/make a normal printer driver that works with your receipt printer, put it on the client box, and just use the normal print js commands.
2) Find/make a browser plugin that talks to the printer and exposes an API.
3) Find/make a simple web app that talks to a server-connected receipt printer (probably via native code execution or script call), and install it on each POS, with CORS to allow remote origin; then just post to that on 127.0.0.1:whatever from the webapp client script.
Side note: I seriously discourage connecting a POS to anything resembling a network any more than absolutely necessary. Every outbound network request or trusted network peer is a potential attack vector. In short, I would never use django or any other web app for physical POS software.
I am building a chat application that consists of a Django web backend with a Node.js/socket.io powered chat server. There will be instances when changes made via the web interface (e.g. banning a user) need to be pushed immediately to the chat server. I can think of the following options:
Use a Python-based socket.io client to interface directly with the server (what are some good Python clients?)
Use redis or a message queue to do pub/sub of events (seems like overkill)
implement a simple TCP wire protocol on a secondary localhost-only port (this could be done using the built-in Node and Python TCP libraries)
What would be the best option?
Expose a Restful API on the chat server. Then your Django web application can easily make API calls to modify state in the chat server.
Doing anything else is more complicated and most likely unnecessary.
