input: Write a function to filter even numbers using a list comprehension.
  assert filterEvenNo([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])==[2, 4, 6, 8, 10]
  assert filterEvenNo([10, 20, 45, 67, 84, 93])==[10, 20, 84]
  assert filterEvenNo([5, 7, 9, 8, 6, 4, 3])==[8, 6, 4]
output: def filterEvenNo(lst):
      return [x for x in lst if x % 2 == 0]
