input: Write a function to iterate over a list of numbers and print only the even numbers. The function should take a list of integers as input and print the even numbers one by one.
  assert even_numbers_list([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])==2 4 6 8 10
  assert even_numbers_list([11, 13, 15, 17])==
  assert even_numbers_list([2, 4, 6, 8, 10])==2 4 6 8 10
  assert even_numbers_list([])==
output: def even_numbers_list(numbers):
      for num in numbers:
          if num % 2 == 0:
              print(num, end=' ')
