SimPy Tutorial 1: Introduction to SimPy

In this video, I discuss some of the reasons SimPy is a good option for discrete event simulation. Then, I demonstrate the difference between a generator (one of the fundamental elements of SimPy) and a function. Finally, I wrap up the video by writing a simple SimPy program to illustrate how timeout events work. Use 1080p for best viewing!
