Hint

🧠 Not sure where to start?

Start by asking the user to enter a list of values (words or numbers), separated by commas:

items_input = input("Enter items separated by commas: ")

Then convert that input string into a list using split(','), and use strip() to remove extra spaces:

original_list = [item.strip() for item in items_input.split(',')]

Now think: how can you remove duplicates from that list? One way is by converting it to a set. But if you want to keep the original order, a loop might be better.

Once you have the cleaned list, calculate how many items were removed:

removed_count = len(original_list) - len(cleaned_list)

Then print both the cleaned list and the number of removed items!
