🚀 Atenção, devs Python! 🚀

Você já ouviu falar em *Primitive Obsession*? É aquele code smell que vira pesadelo quando usamos só *primitivos* (strings, dicts, listas) para modelar dados complexos num sistema. A boa notícia: existe uma saída poderosa e elegante! 💥

No artigo fresquinho *"Primitive Obsession no Python: Refatorando com Dataclasses para Value Objects Robustos"*, inspirado na incrível Live de Python #150 do Eduardo Mendes, você vai descobrir como as **dataclasses** podem revolucionar seu código!

✨ Imagine ter:
- Abstrações de domínio ricas, tipadas e imutáveis
- Código mais seguro e testável, sem KeyError ou lógica espalhada
- Menos boilerplate e alta legibilidade
- Validações incorporadas e comportamento encapsulado
- Facilidade para escalar e evoluir sistemas com menos bugs

Este é o caminho para sair da armadilha dos primitivos e dominar Value Objects com Python moderno! 🚀👩‍💻👨‍💻

Today we fixed a missing abstraction for extracting data from a tab-separated input, based on column name from the header.

We created a new class, ColumnMapper, with an underused refactoring from IntelliJ IDEA: Introduce Parameter Object.

Check it out: https://www.youtube.com/live/CzdfBOKUtw4?t=1248

We extract duplicate code to a method, introduce the Param Object, and prepare to move the method (which now has "Feature Envy") by doing Inline Method (at 40m20). We finish by doing Move Instance Method to move it to ColumnMapper.

This is one of my favorite Composite Refactorings to do!

Friendgineers: George Boole brought us Boolean logic. There's tremendous benefit in using it. But sometimes, it can also blind you to a deeper truth.

Think I have my next talk subject "Strings - The Post Modern Chameleons of Programming". Need a name, a database connection, a path, a password, a date? Strings can be all of these. In fact, one instance could even be all of these, all at the same time or in quick succession!

Been fighting a bug for a few days that turned out to be a post-modern use of strings. I'm not bitter. At. All. #PrimitiveObsession

Are your classes too big? Hard to understand and test? I talk about a great approach for cutting your classes down to size. Video and slides are now available!

Build fails because ReportGenerator "misses a framework" Fine, let's provide it one. Should be simple: ReportGenerator exposes a SetFramework method.

Guess the type parameter it requires.

String.
