The process behind creating a permutation is an important building block for conducting a permutation test. In this lesson, I'll show you how to conduct a permutation test. Feel free to open the corresponding exercise file to follow along. Now, I'll need to permute the data more than once, so it'd be helpful to have a function that I can call whenever I want to permute the data. So I've defined a function that allows me to do this. And I named the function "Perm." I started with the keyword def, followed by the name of the function, which is perm parentheses, and then data.
