| # The original list containing duplicate elements | |
| original_list = [1, 2, 2, 3, 4, 4, 4, 5, 6, 6] | |
| # Use set() to remove duplicates, then convert it back to a list | |
| unique_list = list(set(original_list)) | |
| # Print the new list | |
| print(f"Original List: {original_list}") | |
| print(f"Unique List: {unique_list}") | |
| # Output: | |
| # Original List: [1, 2, 2, 3, 4, 4, 4, 5, 6, 6] | |
| # Unique List: [1, 2, 3, 4, 5, 6] | |
| # The original list where order matters | |
| original_list = ['apple', 'orange', 'apple', 'banana', 'orange', 'grape'] | |
| # Create a dictionary from the list keys (removes duplicates) and get the keys as a list | |
| unique_list_ordered = list(dict.fromkeys(original_list)) | |
| # Print the new list to show the order is preserved | |
| print(f"Original List: {original_list}") | |
| print(f"Unique & Ordered: {unique_list_ordered}") | |
| # Output: | |
| # Original List: ['apple', 'orange', 'apple', 'banana', 'orange', 'grape'] | |
| # Unique & Ordered: ['apple', 'orange', 'banana', 'grape'] | |
