Differences among lists of names


See who's who

Let's check two different lists... that have some names in commons and some other that are not in common...

code explanation

  • make a function that gets the data from two text files with two lists slightly different and puts them into 2 sets
  • give a name (variable) to the two sets
  • put the difference between list 1 and 2 and between list 2 and 1 (set not list, indeed) in others variables
  • show the differences
