Travou na hora de migrar de SQL pra Python? 😅 Somar vendas por país é o MESMO conceito nas 3 ferramentas — só muda a escrita: 🔹 SQL: GROUP BY country 🔹 Pandas: df.groupby["sales"].sum 🔹 Spark: .groupby.agg(sum.alias) Mesmo raciocínio, três sintaxes: agrupar por uma chave e agregar. Quem enxerga o padrão troca de ferramenta sem reaprender do zero. Salva pra não esquecer 👇 #SQL #Python #Pandas #Spark #DataScience
