Write the code to find the singletons within a list. A singleton is a value which only appears once. Print a message if there aren't any singletons in the list. Input: A list of lists: [[5, 7, 8, 7,...

Write the code to find the singletons within a list. A singleton is a value which only appears once. Print a message if there aren't any singletons in the list.

Input:

• A list of lists: [[5, 7, 8, 7, "a", "b", "a", 5], [6, 9, 0, 9, 6, 0]]

Output:

• List [5, 7, 8, 7, "a", "b", "a", 5] has the following singletons
  
  
  
  • 8
  
  
  • b
  
  
  
  


• List [6, 9, 0, 9, 6, 0] does not have any singletons

Partial credit will be granted. The rubric is:

• Processed the lists correctly (20 points)


• Processed the elements within the list correctly (20 pts)


• Logic to identify a singleton (20 pts)


• Logic to generate the outputs (20 pts)


• Comments that describe the logic (20 pts)
