input: Write a function to convert a list of integers into a dictionary where each integer from the list is a key and its corresponding value is a string representation of the integer in words. Then print the values of the dictionary. The function should return the dictionary.
  assert convert_list_to_dict([1, 2, 3, 4])=={1: 'one', 2: 'two', 3: 'three', 4: 'four'}
  assert convert_list_to_dict([5, 6, 7, 8])=={5: 'five', 6: 'six', 7: 'seven', 8: 'eight'}
  assert convert_list_to_dict([])=={}
output: def convert_list_to_dict(lst):
      num_to_words = {1: 'one', 2: 'two', 3: 'three', 4: 'four', 5: 'five', 6: 'six', 7: 'seven', 8: 'eight'}
      return {num: num_to_words[num] for num in lst if num in num_to_words}
