New protocols, technologies, and delivery and O&M modes are emerging in the network engineering field. Conventional networks face challenges from new connection requirements, such as requirements for cloud computing and artificial intelligence (AI). Enterprises are also pursuing service agility, flexibility, and elasticity. Against this backdrop, network automation becomes increasingly important. Network programmability and automation is to simplify network configuration, management, monitoring, and operations for engineers and improve deployment and O&M efficiency. This course is to help network engineers understand Python programming and implement network automation.
