A quick GitHub gist for anyone looking to write to an InfluxDB server with Python3. This is a generic function that accepts three inputs; as an example, I am using temperature data in degrees Celsius. Turning DHT11 readings into beautiful graphs in Grafana Once you have your data in influxDB, a great way to visualise it is using Grafana. I hope to bring you more posts in the future about visualising your python data with Grafana. ...
I have covered this a number of times in the past and the posts have proved popular and useful to many. So, here is my guide for updating to the latest version of Python 3 (3.9) on Debian 10 Buster. To clarify the purpose of this guide, Debian 10 ships with Python 2 (2.7) and Python 3 (3.7) installed at my time of writing. For those wishing to upgrade from python 3.7.X to 3.8.X or 3.9.X, this is the guide for you. If you are trying to configure python 3.7 as your default interpreter when you call ‘python‘, try this: CHANGING THE DEFAULT PYTHON VERSION IN DEBIAN. This method involves using the ‘update-alternatives‘ command. We will be using a similar method in this guide, however this time we only do so to give 3.9.X a higher priority to 3.7.X, rather than uninstalling older versions. ...
Compound stonks only go up! I have a growing interest in finance and analytics, so it felt like a great idea to start creating my own set of financial tools with Python. This article will explain how I created a simple but effective script for calculating compound interest with Python. I wrote this in Python 3 (as all new Python projects should be from now onwards), but the library dependencies are very lightweight, making this something that could easily be re-written from Python 2. ...
A quick Google of the above only seemed to give me answers for the inverse, calling a python script from a bash shell and handing it variables. At least, the first 3 results showed this and I’m probably not alone when it comes to scrolling down past the StackOverflow articles. So I am had to go it alone and the way that I figured out how to call a bash command with variables in Python (3), is a total hack… But it works. This is commonly referred to as ‘getting the job done’ code. ...
Here is a quick guide on how to create an infinite loop in python using a ‘while true’ statement. There are number of reason that you might want to implement this; a great use case would be outputting a fluctuating variable to the terminal such as a temperature reading from a sensor. loops that make your brain hurt A ‘while true’ statement allows us to run a sequence of code until a particular condition is met. In order to make that sequence of code run in an infinite loop, we can set the condition to be one that is impossible to reach. Better still, we can simply omit the condition altogether to ensure that the while true loop never ends. ...
