SAP enjoys a brand reputation in China, and many multinationals and large companies use their large enterprise ERP solutions. But for the midsize market (within 1000 people), SAP faces a fierce impact from cloud-based ERP systems like NetSuite. While SAP provides solutions for both large and medium-sized enterprises, the ERP solution provided by NetSuite is specifically tailored to the branch offices of mid

Single responsibility principle, SRP is the first of S.O.L.I.D's five design principles advocated by Uncle Bob. Among them, the responsibility (responsibility) is expressed as "the cause of Change" (reason); the SRP is expressed as "the reason that a class should have and only one change." But if the light is literally understood, the SRP can easily be misunderst

Architecture is not mentioned throughout the entire serialization, because no particular architecture model is named, and architecture design is a philosophy. You must learn to use it freely, just like playing Taiji, virtual is real, non-virtual is not industrial. If you want to do things, do not take the attitude of doing things to do things. You must learn to be crazy, impulsive, and essential qualities in art creation. Programming is also a must for things. Throughout the entire article, I wi
that we have a clear definition of the problem, let me try to break it down into the simplest possible part, and then resolve the parts individually. I have seen two separate parts for this issue. The first part is writing a function that receives an IP address or subnet range and returns a list of MAC addresses or MAC addresses. We can then consider integrating it into the command-line tool after solving the problem.Solution Part 1th: Create a Python function that determines the MAC address by
