Final answer:
To create a list with unique elements from one with duplicates, convert the list to a set to remove the duplicates, then back to a list. In Python, this can be done using the `set()` and `list()` functions. The set data structure is key for ensuring uniqueness.
Step-by-step explanation:
To produce a list with unique elements from a list with duplicate elements, you can use a data structure known as a set. Sets are designed to hold only unique items, so when you convert a list into a set, any duplicate elements will be automatically removed. After converting the list to a set to eliminate duplicates, you can convert it back to a list if needed. Here's an example in Python:
# Given list with duplicates
my_list = [1, 2, 3, 2, 1, 4, 4, 5]
# Convert list to set to remove duplicates
my_set = set(my_list)
# Convert set back to list (if needed)
unique_list = list(my_set)
print(unique_list)
When the last line of this code is executed, 'unique_list' will contain only the unique elements from the original 'my_list'. In this case, the output would be [1, 2, 3, 4, 5], with all duplicates removed.
