'Set' variable type missing from list of variable types

Hi in the video titled “Understanding the Variable Block” in the Terraform Basics course, the variable type of ‘set’ is missing in the list of types at 1:31 of the video. It is also missing in the attached pdf file with the course. Please have it updated.

Hello,
Thanks for reporting this.
on the lecture the instructor mentioned the most usable variables in Terraform but as you mentioned there are for sure other different variables that didn’t be mentioned.

But he has explained it later in the video. the pdf needs to be updated with the ‘set’ type in that page.
