Protocolos de Internet e Suporte¶
Os módulos descritos neste capítulo implementam protocolos de internet e suporte para tecnologia relacionada. Todos eles são implementados em Python. A maioria desses módulos requer a presença do módulo dependente do sistema socket
, que atualmente é suportado na maioria das plataformas populares. Segue uma visão geral:
