For a container class with a dictionary with config values (among other members) I wanted easy reading access as if it was a dict itself. For that you only have to implement the __getitem__ method. You can extend the provided dict functionality for your class if needed like the following: All but the update method…
As most of the time – there are multiple valid ways of doing it. Keeping the order I prefer easy and readable, if it is not crucial for performance to go another way.Create a new list and add only values to it that are not already included. You can do this with a simple list…
Yeah I know it’s kinda pointless. I was thinking the same thing when I doomscrolled youtube shorts watching a so called programmer “Herr Programmierer” showing a simple script moving the mouse in a fixed interval to coordinates in a fixed square. I was bored, I like Python and sure I could create a better pointless…
Yeah we all can loop, but can you any or all? Checking if condition matches for at least one element of an iterable (e.g. list, tuple, set) In Python you can write that nicer with the builtin method any(): But who doesn’t like a one-liner (that is understandable): Very similar is the case if you…
The little easter egg of “import this” in Python is well known – it shows Zen of Python. Nice guideline of how to keep your code clean. The Zen of Python, by Tim Peters Beautiful is better than ugly.Explicit is better than implicit.Simple is better than complex.Complex is better than complicated.Flat is better than nested.Sparse…
A little util to map direction angle from weather API to ‘NW’ (SHORT, default) or ‘north west’ (LONG). Supports english (default) and german. An example API call to the weather API I am using and mapping the current wind direction to readable format. All my weather related code at github https://github.com/worksonmymachine-de/weather.
Just wanted to let you know I wrote a little mapper / translation for WMO weather codes as the (free) API I use for current weather and forecast also provides it. An example API call to the weather API I am using and mapping the current weather code to readable format. The code is on…
Most code for simple IoT devices is a script with an endless loop with the code for the connected hardware like reading a sensor or polling something from the network followed by a delay. Keeping that pattern in mind helps to write new or convert your existing code for asynchronous execution. If you want to…
TLDR: Code for MAC address in (Micro)Python and C++ for D1 Mini, Raspberry devices and NodeMCU. I was looking for a unique static identifier to handle my IoT devices without baking the mqtt publish topics, name and location into the code. The code on identical devices should be the same, the the individual configuration should…
Write them. Do not try to save time writing them poorly or even not at all. You and your coworkers and even often your future self will appreciate the work you put in. Many many times I found probable issues, uncovered cases and bugs lurking in my code I wrote by testing the code step…
Sweet and short: Instead of a function you can write a single statement in Python as a lambda. Either is one either better or worse nor does one replace the other. They both have their place and intended use. Functions hopefully have describing names, are probably used multiple times and handle a specific part which…
Currently did some text analysis with Python and Regex. Came up with an E-Mail format validation method which could help you with the same problem and remind me of it in the future. Import package re and use the compile method to get a regex pattern with which you can match your desired String.For evaluation…
