If it were me, I'd start with Geotab's developer api for programmatically tapping into the feeds of near real time vehicle movement, combined with ESRI's python api for creating and updating feature services on Arconline. I bet you could get near real time if you run the updates fairly frequently, like maybe once or twice a minute, depending on your needs. Source: almost 2 years ago

If you are used to Python and Jupyter Notebooks, you should definately get your hands dirty with https://developers.arcgis.com/python/. Source: about 2 years ago

Have you looked at ArcGIS API for Python? It's not the same as arcpy, but used more for working with Esri's portals. Source: about 2 years ago

We are very heavy into using the ESRI suite of tools and which languages I use depend heavily on the project I am working on. I would say I mostly use Python, but mainly with the ArGIS API for Python, not arcpy. I do use quite a bit of javascript to develop UIs for widgets as well, but that is not anywhere near as common.

Once you have your foundation, then https://developers.arcgis.com/python/ and https://developers.arcgis.com/documentation/arcgis-add-ins-and-automation/arcpy/ become much easier to understand. Also be aware that you can run Geoprocessing Tools in ArcGIS Desktop and in the Geoprocessing History, copy out the Python snippets to add to your code and automate. Source: almost 3 years ago

TurboGears is another Python web framework that is scalable. It starts as a microframework and can scale up to a full-stack framework. - Source: dev.to / over 2 years ago

Building, constructing, and maintaining websites is a broad definition of web development. A front-end, which communicates with the client, and a back-end, which contains business logic and interacts with a database, are typical components of web development. Python also supports quite a percentage of the total websites, web apps and software running in the world wide web. The libraries that are applied in web... - Source: dev.to / about 3 years ago

I've pretty much tried every Python web framework that exists, and it took me a long time to realize there wasn't a silver bullet framework, each had its own advantages and disadvantages. I started out with Snakelets and heartily enjoyed being able to control almost everything at a lower level without much fuss, but then I discovered TurboGears and I have been using it (1.x) ever since. Tools like Catwalk and the... Source: about 3 years ago

Unfortunately, there doesn't seem to be many really popular MVC frameworks for Python. There IS Turbogears, but it doesn't seem that popular. https://turbogears.org/. Source: about 4 years ago
