 WRITE A PYTHON PROGRAM TO FIND THE SECOND SMALLEST NUMBER IN A LIST.

INPUT:

def second_smallest(numbers):

  if (len(numbers)<2):

    return

  if ((len(numbers)==2)  and (numbers[0] == numbers[1]) ):

    return

  dup_items = set()

  uniq_items = []

  for x in numbers:

    if x not in dup_items:

      uniq_items.append(x)

      dup_items.add(x)

  uniq_items.sort()    

  return  uniq_items[1]   

print(second_smallest([1, 2, -8, -2, 0, -2]))

print(second_smallest([1, 1, 0, 0, 2, -2, -2]))

print(second_smallest([1, 1, 1, 0, 0, 0, 2, -2, -2]))

print(second_smallest([2,2]))

print(second_smallest([2]))
