"String side of things vs list side"?

I'm confused on what that statement Craig made about .join being on the string side of things vs the list side.

to_line = ", ".join(attendees) attendees is a list, the items inside are strings.

What does he mean by .join being on the string side of things? Does he mean you can't use .join to join two lists together?

Hey Aaron Elkind ! :wave:

The .join() method in Python is specifically a string method that is used to join a list of strings into a single string, using the given string as a delimiter. It cannot be used directly to join two arrays (or lists) together.

To join two lists together you could use the + operator...

list1 = [1, 2, 3]
list2 = [4, 5, 6]
joined_list = list1 + list2

Or the extend() method...

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list1.extend(list2)

I'm sure there are also other ways that I'm not aware of. I hope this helps out! :smiley:
