A primeira edição deste livro foi publicada em 2012, numa altura em que as bibliotecas de análise de dados de código aberto para Python, especialmente o pandas, eram muito recentes e estavam a desenvolver-se rapidamente. Quando chegou a altura de escrever a segunda edição, em 2016 e 2017, precisei de atualizar o livro não só para o Python 3.6 (a primeira edição utilizava o Python 2.7), mas também para as muitas mudanças no pandas que tinham ocorrido nos cinco anos anteriores. Agora, em 2022, há menos alterações na linguagem Python (estamos agora no Python 3.10, com o 3.11 a sair no final de 2022), mas o pandas continuou a evoluir.
Nesta terceira edição, o meu objetivo é atualizar o conteúdo com as versões atuais do Python, NumPy, pandas e outros projetos, ao mesmo tempo em que me mantenho relativamente conservador em relação à discussão de novos projetos Python que surgiram nos últimos anos. Uma vez que este livro se tornou um recurso importante para muitos cursos universitários e profissionais, vou tentar evitar tópicos que correm o risco de ficar desactualizados dentro de um ou dois anos. Desta forma, as cópias em papel não serão demasiado difíceis de seguir em 2023, 2024 ou mais tarde.
