TypeError: unsupported operand type(s) for -: 'list' and 'list'

Question

I am trying to implement the Naive Gauss and getting the unsupported operand type error on execution. Output:

  execfile(filename, namespace)
  File \"/media         


        

Answer 1

Use Set in Python

>>> a = [2,4]
>>> b = [1,4,3]
>>> set(a) - set(b)
set([2])
