    Checklist para propostas de talks para Python Brasil
Tema

 Escolhi um tema relevante para a audiência. Imaginei quem estará na conferência e pensei: "sobre o que essas pessoas querem/precisam ouvir?"
 Escolhi um tema enriquecedor, que trará um novo aprendizado para minha audiência
 Escolhi um tema que já me sinto confortável em falar ou terei tempo suficiente para estudar para me sentir confortável
 Escolhi um tema que é possível apresentar em 35 minutos
 Escolhi um único tema e não um conjunto de temas pouco relacionados
