Example 1: Using set()
list_1 = [1, 2, 1, 4, 6]
print(list(set(list_1)))Output
[1, 2, 4, 6]
In the above example, we first convert the list into a set, then we again convert it into a list. Set cannot have a duplicate item in it, so set() keeps only an instance of the item.
Example 2: Remove the items that are duplicated in two lists
list_1 = [1, 2, 1, 4, 6]
list_2 = [7, 8, 2, 1]
print(list(set(list_1) ^ set(list_2)))Output
[4, 6, 7, 8]
In the above example, the items that are present in both lists are removed.
- Firstly, both lists are converted to two sets to remove the duplicate items from each list.
- Then,
^gets the symmetric difference of two lists (excludes the overlapping elements of two sets).
