Python *args and **kwargs are super useful tools, that when used properly can make you code much simpler and easier to maintain. Large manual conversions from a dataset to function arguments can be packed and unpacked into lists or dictionaries. Beware though, this power can lead to some really unreadable/unusable code if done wrong. /* h2 {display: block;} */ h2>img { margin: auto; width: 100%;} Python *args and **kwargs are super useful tools, that when used properly can make you code much simpler and easier to maintain.

I recently discovered the ✨ awesomeness that is pre-commit. I steered away from it for so long because it seemed like a big daunting thing to set up, but really it’s easy. It will automatically run checks for you. In some cases, it will even automatically fix them for you. Out of the box, it will do things like automatically trim extra whitespace, fix file endings, and ensure file sizes are not too large for git [1].

Follow along the Journey as I build out kedro.dev [1]. Building a Community # [2] I have really enjoyed my own personal journey as I have started to build all of my data pipeline projects with the kedro framework. I want to start building a place to share resources with the community. I want to see this community grow and flourish. They say in front end web development if you are not using a framework you end up building one. That’s exactly what I was doing before I started using kedro. I want to build out a set of resources that this community can learn from and start to use the framework at their own pace without needing to develop their own from scratch. research # [3] Looking into the front end frameworks to see how they welcome their community. Much of my inspiration is from them, bringing lessons learned to data. pages # [4] - banner - nav - docs -> readthedocs - tutorial -> kedro-examples - blog -> medium - community - support - team - courses - examples - mee...

kedro-static-viz [1] is out with support for the newly released hooks feature. This means that you can have kedro-static-viz automatically deploy a full gatsby site before_pipeline_run keeping your visualization always up to date. Even though it is a static site there is no functionality lost. The only thing that’s missing is the flask server. With kedro-static-viz [1] you can deploy your visualization to a number of static hosting providers such as GitHub pages free of charge with wicked fast performance ⚡ It’s Fast # [2] Even though it’s built on gatsbyjs the full site builds in under 2s even on slower hardware. This is because the site is already pre-rendered and stripped of any excess. It’s zipped up right into the python package and is typically used with the cli, but now can be used with python, or as a hook as well. What is kedro-viz [3] 🤔 # [4] Kedro viz is a fantastic kedro plugin that allows you to visualize your data pipeline. Kedro allows you to quickly build produc...

There are two main ways to create kedro hooks, with modules and classes. Each one still uses the same verbiage as the function/method names. Class hooks seem a bit special as they give you a way to configure them so that they are a bit more generally useful. What is Kedro [1] If you are completely unsure what kedro is be sure to check out my what is kedro [2] post Installation # [3] .create a new environment manager of choice. Here I will use conda. Then we will install kedro from pypi. conda create -n kedro_class_hooks -y conda activate kedro_class_hooks # may also be source activate kedro_class_hooks or activate kedro_class_hooks pip install kedro Create a sample project # [4] Kedro new # [5] For more details check out my full post on kedro new [6] For this post I really just want a working pipeline as fast as possible. For this I am going to use iris pipeline that is generated from the kedro new command in the cli. It’s important that you answer y to create an example pi...

I want to incorporate some of the wonderful comments, \U0001F495, \U0001F984, and \U0001F516’s that I have been getting on dev.to on my website. I have dabbled once or twice with no avail this time I am taking notes on my journey, so follow along and let’s get there together.

GitHub’s actions are a new GitHub feature that will trigger GitHub to spin up a virtual machine and run some tasks with some special access to your repo. It can interact with comments/issues, it can clone your repo, You can explicitly pass in secrets so that it can commit back to the repo or deploy to another service. The environment may be a Linux, windows, or even a mac machine. I believe this is wildly incredible for the open-source community, putting these tools in the same place that we are already collaborating is so convenient. What can they do for my personal website? 🤔 # [1] GitHub actions can give you confidence that your site is up and running, with the latest JavaScript packages, does not have broken links, and can even take screenshots of what your website looks like on different screen sizes and operating systems. - periodically check that the website is up - update npm - url checker - screenshot website srt32/uptime [2] # [3] srt32/uptime [2] is an action that...

Kedro provides an efficient way to build out data catalogs with their yaml api. It allows you to be very declaritive about loading and saving your data. For the most part you just need to tell Kedro what connector to use and its filepath. When running Kedro takes care of all of the read/write, you just reference the catalog key. But what is happening behind the scenes # [1] Under the hood there is an AbstractDataSet that each connector inherits from. It sets up a lot of the behind the scenes structure for us so that we dont have to. For the most part kedro has connectors for about anything that you want to load, csv, parquet, sql, json, from about anywhere, http, s3, localfile system are just some of the examples. Here is a DataSet implementation from their docs. Here you can see the barebones example straight from the docs. Parameters from the yaml catalog will get passed in from pathlib import Path import pandas as pd from kedro.io import AbstractDataSet class MyOwnDataSet(...

As usual while listening to python bytes 181 [1] I heard of a tool that I had to try out right away! This thing is 🔥 hot off the press folks, we’re talking the first release only 3 weeks ago. Its something that the python community needed years ago, and it belongs in your CI today. I had tried several tools that tried to do docstring coverage in the past but they were a bit cumbersome and were quickly forgotten about. Not interrogate, its dead simple! Nothing I have tried has come close to being this good Interrogate # [2] It runs documentation coverage for your python project. It allows you to set the minimum amount of docstring coverage for your project and has some great setup instructions right in the readme. Install it # [3] Interrogate is on pypi so it is super simple to install with pip pip install interrogate run it # [4] This is the best part, its super easy to run right from the command line! Just call it, and give it a path to run. interrogate -v <path> 😲 I hav...
