In this chapter, we discussed some more advanced concepts of Python, which allow us to increase the throughput. We discussed multiprocessing Python modules and how they can be used to reduce the time taken and increase our processing capabilities. With this chapter, we have essentially covered everything that we would need from Python for us to step into the world of penetration testing, automation, and various cybersecurity use cases. It should be noted that, from here on, our emphasis will be on applying the concepts we have studied so far, with less explanation as to how they work. For this reason, if you have any doubts, I would strongly recommend that you clarify these before moving ahead. In the next chapter, we will talk about how can we use Python to parse PCAP files, automate Nmap scanning, and much more. For all security enthusiasts, let's get to business.
