Okay, in Python programming, we can select multi variables and multi rules. We can do this using da da da da. So the DA law. So let's say I want to select a first 30 rows, then I can select, let's see, ah, two variables here. I can say that I see a set name and maybe I changed to pick the line. Okay, then I can run the code that we saw that first study role for sepal length and petal length.
