Introduction to Implementing a CLI
00:00 In this section, I’ll be showing you how to implement a command line interface in bare Python, by which I just mean that I won’t yet show you how to use the existing libraries that Python offers you to construct command line interfaces—I’ll be showing you how to do it from scratch.
00:15
In the process, I’ll be dealing with a couple of Linux utilities: one called seq and then another called sha1sum. I’ll be showing you how to implement some basic duplicates of those two utilities, so I’ll get more into those as I work through the code.
