Edit Question
Title
Body
I have a list containing multiple lists as its elements eg: [[1,2,3,4],[4,5,6,7]] If I use the built in set function to remove duplicates from this list, I get the error TypeError: unhashable type: 'list' The code I'm using is TopP = sorted(set(TopP),reverse=True) Where TopP is a list just like in the e.g. Above Is this usage of set() wrong? Is there any other way in which I can sort the above list?
