 | **Docstring**         | We use a slight variation of Numpy convention with markdown to help generate more readable API references.                                                                                                                                                                  |
-| **Style guide**       | We use black as well as flake8 extensions to enforce beyond good practices [PEP8](https://pep8.org/). We use type annotations and enforce static type checking at CI (mypy).                                                                                                |

 | **Core utilities**    | Core utilities use a Class, always accept `service` as a constructor parameter, can work in isolation, and are also available in other languages implementation.                                                                                                            |
 | **Utilities**         | Utilities are not as strict as core and focus on solving a developer experience problem while following the project [Tenets](https://docs.powertools.aws.dev/lambda/python/#tenets).                                                                                        |
 | **Exceptions**        | Specific exceptions live within utilities themselves and use `Error` suffix e.g. `MetricUnitError`.                                                                                                                                                                         |
