Dedicated time for learning Python at work

In the spring of 2019 I had the opportunity to use some paid work time for learning something new.
I decided to spend the given time to brush up on my Python knowledge. I had some experience in programming with Python but not much and I didn't have a understanding of Python conventions or ecosystem.

Limited time frame

I had a limited time frame that was split to four sessions. In addition to the time given for each session I spent at least the same amount of time on preparing each session.

First session, the basics

It was quite hard to find a resource that summarised Python basics on a sufficient level but I managed to find Alex Martinelli's slides Python for Programmers from 2007 that contained exactly what I was looking for.
Even though the slides are from over a decade ago and the Python version was 2.x at that time all the information is still applicable to current Python 3.x version as is or with minor changes.

Second session, testing in Python

Python has a good support for automated tests and it wasn't too hard to find two good resources where to learn. First I read a short introduction to Python's unit testing libraries from the Hitchhiker's guide to Python. After that I went through a longer, more profound, tutorial from Real Python.

Third session, functional programming in Python

I knew that Python supported functional programming concepts and the best resource that I could find was Python's own documentation that also explained some of the gotchas I ran into in my earlier Python programming experiments e.g. map function returns a iterator not a list or set or what ever was the input's type.

Fourth and final session, asynchronous programming in Python

With the rise of FRP and the Reactive Manifesto I thought that introducing myself to Python's async IO would be a good idea. For me the Real Python's tutorial on async IO was the easiest to understand and I think it's quite comprehensive.

Syllabus for Python for programmers

  1. Basics, Alex Martinelli's slides http://www.aleax.it/goo_py4prog.pdf 
  2. Testing, the Hitchhiker's guide to Python https://docs.python-guide.org/writing/tests/ and Real Python's getting started with testing in Python https://realpython.com/python-testing/ 
  3. Functional programming, Python's own documentation https://docs.python.org/3.7/howto/functional.html 
  4. Async IO, Real Python's tutorial on async IO https://realpython.com/async-io-python/

Conclusion

It took me around 6 hours to read and somewhat understand the contents of all the resources of the sessions. I already knew Python's syntax and had a solid understanding of other programming languages and I knew all the concepts that were covered.

I haven't worked with Python since the sessions but next time that I will, I'll first browse through these resorces.

DIY home automation v2

Previously I set up a simple home automation system for controlling outlets at home. So far I've used the system for controlling various lights at our home. I've been satisfied with oulet controlling via browser but I wanted something more. Objective I had a idea of temperature and humidity monitoring via Raspberry Pi. I was already browsing for electronics components needed for building a system with sensors but buying single components seemed a bit expensive and I would also have to actually connect all the components to RPi and write the code to read the sensor data. Mainly because of the price the components I started looking for a pre-built system with the preferred sensors. Almost immediately I came across Proove's sensor that has indoor and outdoor temperature sensors and a indoor humidity sensor. Best part of the pre-built system is that it's already compatible with TellStick system that I used for controlling outlets. I decided to buy the pre-built s

DIY home automation, new generation

I've had my DIY home automation system for controlling outlets and reading sensor data running for about two years now. The system has been working fine and I haven't had any need to touch the code since I added the sensor reading to it, until a few months back. Need for new functionality Few months ago I got a new IoT toy for a lend from a friend until I'd get my own toys, a ruuvitag sensor beacon. Ever since I found the ruuvitag for the first time from kickstarter I had the idea of getting a bunch of ruuvitags and adding their weather station sensor readings as part of my home automation system. The original home automation backend included only tellstick compatible devices and was written in Python, and in my mind it was kind of a hack. The ruuvitag beacons communicate via BLE i.e. Bluetooth Low Energy and that meant that I needed to add functionality to read the beacon data via bluetooth. I found a ruuvitag Python library and initially thought that I'd just

Automated browser testing in 2018

Every now and then I do some research on browser testing. More specifically I try to find and evaluate what kind of ready to use solutions or libraries have emerged since my previous research or if some of the previously tested solutions has come up with something new. Back in September 2017 I had some extra time on my hands and I used a couple of days to see what are the new and interesting solutions at that time. I came across some tools that I have used in the past and found two new interesting options in which one stood out. Say hello to TestCafe The most interesting solution that I found was called TestCafe . It's a open source Node.js library from a company called Developer Express Inc. They also have a commercial product called TestCafe ( confusing ) which I haven't tried as the open source library provided everything I was interested in and it seemed to be under active development . The thing that caught my interest at first was that this library doesn't depen
