input: Write a function to find the intersection of two sets of integers. The function should take two sets as input and return the intersection of those sets.
  def intersection(set1, set2): 
     return set1 & set2
  
  set1 = {1, 2, 3, 4}
  set2 = {3, 4, 5, 6}
  result = intersection(set1, set2) 
  print(result)
output: def intersection(set1, set2): 
     return set1 & set2
