Python 3 Programming Tutorial - Sys Module
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

Definition of an Injective Function and Sample Proof
We define what it means for a function to be injective and do a simple proof where we show a specific function is injective. Injective functions are also called one-to-one functions. Useful Math Supplies https://amzn.to/3Y5TGcv My Recording Gear https://amzn.to/3BFvcxp (these are my affil

Definition of a Surjective Function and a Function that is NOT Surjective
We define what it means for a function to be surjective and explain the intuition behind the definition. We then do an example where we show a function is not surjective. Surjective functions are also called onto functions. Useful Math Supplies https://amzn.to/3Y5TGcv My Recording Gear ht
