pytest has open sourced their amazing plugin framework pluggy, it allows library authors to give their users a way to modify the libaries behavior without needing to submit a change that may not make sense to the entire library. Previous Experience # [1] My experience so far as a plugin user, and plugin author has been great. Building and using plugins are incredibly intuitive. I wanted to dive a bit deeper and see how they are implemented inside of a library and its a bit of a mind bend the first time you try to do it. Plugins vs. Hooks # [2] A hook is a single function that has a specific place that it is ran by the PluginManager. A Plugin is a collection of one or more hooks. Layers # [3] - library author - plugin author - end user Using a plugin # [4] For a plugin to be registered is must be registered by the PluginManager which is implemented by the library author. It is the job of the library author to determine what plugins are actively registered or disabled. Ther...

There are various ways to configure python tools, config files, code, or environment variables. Let’s look at a few projects that allow users to configure them through the use of config files and how they do it. Motivation # [1] This will not include how they are implemented, I’ve looked at a few and its not simple. This will focus on where config is placed and the order in which duplicates are resolved. The motivation of this article is to serve as a bit of a reference guide for those who may want to create their own package that needs configuration. Flake8 # [2] Global # [3] User settings can exist in the users ~/.config/flake8 file to configure how flake8 runs on their machine. - ~/.config/flake8 Per-Project # [4] Only One project config file will be considered, but allows for several options. These files all use the ini format and must have a [flake8] section header to be consideered. Selection of the config file can also be overridden by the --config cli option. An e...

Init signature: Pipeline( nodes: Iterable[Union[kedro.pipeline.node.Node, ForwardRef('Pipeline')]], *, tags: Union[str, Iterable[str]] = None, ) Docstring: A ``Pipeline`` defined as a collection of ``Node`` objects. This class treats nodes as part of a graph representation and provides inputs, outputs and execution order. Init docstring: Initialise ``Pipeline`` with a list of ``Node`` instances. Args: nodes: The iterable of nodes the ``Pipeline`` will be made of. If you provide pipelines among the list of nodes, those pipelines will be expanded and all their nodes will become part of this new pipeline. tags: Optional set of tags to be applied to all the pipeli...

Nesting loops inside of each other in python makes for much harder code to understand, it takes more brain power to understand, and is thus more error prone than if its avoidable. One issue with this complexity is that toy examples may make sense, but most real example will grow and become more deeply nested over time. Avoiding this complexity from the start can help simplify the project in the future. setup # [1] Lets take a pretty simple example where we are using a ficticious library to get some sales data for our transportation company. The api allows us to fetch teh sales data for one class of vehicle and one region at a time. import pandas as pd from datastore import get_sales # ficticious library cars = ['sedan', 'coupe', 'hatchback'] regions = ['US', 'CA', 'MX'] ❌ Nesting Loops # [2] We have setup to fetch our data with two lists that represent the vehicles and regions that we want to analyze. We know that we need to make a call to get_sales for every vehicle and regio...
