input: Write a function to create a Python generator that returns numbers from a given list.
  
  ### Example Input:
  - [1, 3, 5, 7, 9]
  
  ### Example Output:
  def list_generator(input_list):
      for item in input_list:
          yield item
  
  assert list(list_generator([1, 3, 5, 7, 9])) == [1, 3, 5, 7, 9]
  assert list(list_generator([2, 4, 6, 8, 10])) == [2, 4, 6, 8, 10]
  assert list(list_generator([])) == []
  assert list(list_generator([10])) == [10]
output: def list_generator(input_list):
      for item in input_list:
          yield item
