No entanto, a história da importação de módulos é mais rica do que parece até agora. Este capítulo a amplia para apresentar pacotesde módulos — coleçõesde arquivos de módulos que normalmente correspondem a pastas (também conhecidas como diretórios) no seu dispositivo. Ele aborda quatro tópicos:
Importações de pacotes, que fornecem parte do caminho da pasta que leva a um arquivo
Os próprios pacotes, que organizam módulos em pacotes de pastas
Importações relativas a pacotes, que usam pontos dentro de um pacote para limitar a pesquisa
Pacotes de namespace, que criam um pacote que pode abranger várias pastas
Como você verá, a importação de um pacote transforma uma pasta no seu computador em outro namespace Python, com atributos correspondentes aos arquivos de módulo e subpastas que a pasta contém. Como você também aprenderá, as importações de pacotes às vezes são necessárias para resolver ambiguidades quando vários arquivos de programa com o mesmo nome estão instalados em um dispositivo.
