It says to use the .extend() method in the fourth instruction and I don’t think I’ve been introduced to that before so I had no way to know to use that. I looked through all the code to try to find the .extend() method to no avail, so now i’m here asking what it’s about.

I know its been a while since you asked, but since i stumbled with the lesson today, i’m gonna give an answer.

Python commands and functions are way bigger than Codecademy lessons. You need to use other sources to feed your curiosity. I knew about .extend() because of that, it was my first choice. There is another option += that is also valid, but for some reason i forget that it works with lists too (i use it mostly with counter variables).
