My Code:
def unique(a_list):
return set(a_list)
Correct answer:
def unique(a_list):
return list(set(a_list))
Why the need for the list() before set()?
Hi @AntnioSDaCunha,
According to the task, we have to create a function that returns a list. Using set(a_list), we render the initial input a_list into a set, and as a result, remove the duplicated items from it, if there are any (because a set is an unordered collection of distinct items). Next, to transform the result back to a list type, we use list(set(a_list)) and then return the resulting list.
