Review Split and Join Quiz
Question 1 of 2
If I had a list and I wanted to turn it into a string by combining each value together with a specified separator.
What method would I use?
A split. It's on lists.
B join. It's on lists.
C split. It's on strings.
D join. It's on strings.
What do we mean by: "I'ts on lists", "its on strings"
My brain is having a hard time parsing this question. Can someone please explain to me the "Its on" part...not sure i get it
So far, my understanding is that the Join method will output each element of a list as a clean compact string that we can display to a user. On the other hand, the split method does the opposite it turns a string into a list that we can play with.

"a string".method(["a", "list"]) # this method is "on" strings, and takes a list argument
["a", "list"].method("a string") # this method is "on" lists, and takes a string argument
Since you know the name of the method, that puts you halfway there. Now if you identify the syntax you can pick the correct answer.

Thank you Kris, for both the link and the hint ;)
