input: Write a python function to count the number of even and odd numbers in a list.
  assert countNumbers([2, 9, 4, 8, 0, 7, 1]) == (4, 3)
  assert countNumbers([1, 3, 5, 7]) == (0, 4)
  assert countNumbers([2, 4, 6, 8, 10]) == (5, 0)
  assert countNumbers([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) == (5, 5)
output: def countNumbers(lst):
      even_count = sum(1 for num in lst if num % 2 == 0)
      odd_count = sum(1 for num in lst if num % 2 != 0)
      return (even_count, odd_count)
