Have you ever been in a situation where you check your pipelines to see if he’s finished running the tests and you find that he hasn’t even started because you forgot to run the linters locally? I contribute to the development of PyCon Italia (https://pycon.it), Strawberry GraphQL (https://strawberry.rocks) and Poetry Package Manager and coding with these organizations I discovered fantastic tools such as pre-commit (https://pre-commit.com/), Poetry (https://python-poetry.org) and many others. In this talk I would like to share with you my findings, think about the pros and cons and understand a little bit better why you should start using them.
