Let's have a look at some of the fundamentals of using lists in Python. In a new Grasshopper file, let's go ahead and place a Python component and double click to open it up. Creating a list can be done in a few different ways. The simplest method is by using two square brackets, open, then closed. This will create an empty list. For example, let's create an empty list by creating a variable named empty list and I'll assign to this two square brackets, open, then closed.
