Portanto, no OpenAPI, cada um dos métodos HTTP é chamado de "operação".

Vamos chamá-los de "**operações**" também.

/// info | "Informação"

Se você já sabe sobre ambientes virtuais, como criá-los e usá-los, talvez seja melhor pular esta seção. 🤓

/// tip | "Dica"

Um **ambiente virtual** é diferente de uma **variável de ambiente**.
