I don't know why but I'm just not understanding this example: "One of the most common ways you'll see sets being used is to make some other iterable unique. For example, say you have a list of page numbers where terms appear in a book. Since some pages could contain multiple terms, you're likely to get repeats. In that case, you'll see people doing code like this:
pages = list(set(pages)) "

Assume 'pages' variable below has the page numbers in a book where a search word appears.
The page numbers are repeated because the search term appears multiple times in the same page.
pages = 1,1,2,3,4,4,4,5,5,1,1
'set' will allow to remove the duplicate page numbers and return the unique ones.
the outer 'list' will just convert the set to list type.
list(set(pages))
Output will be [1, 2, 3, 4, 5]
