This video covers some of the basics to the sys module in Python 3. The sys module allows you to use stdin() and stdout(), as well as stderr()… but, most interestingly, we can utilize sys.argv(). To many this is a confusing concept, but it is pretty simple and very useful once you learn it. The idea of sys.argv is to allow you to pass arguments through to Python from the command line.
This ability acts as a bridge to the ability to communicate between Python and other languages.
