That is not what the error message says. You said that this line of code:

    set1=set(list1)

gives this error:

    TypeError: unhashable type: 'list'


Almost certainly, either you are mistaken about the line of code which 
gives the error, or you are mistaken about the error, or you are mistaken 
that your list does not contain any lists.

Exactly what Peter suggested: print the list before you try to convert it 
to a set, and see what it actually contains.

It will also help you to read this page and try to follow its advice:
