How to remove duplicates from a list

How to remove duplicates from a list?

Starting with Python 3.7, dictionary is insertion-ordered. So, dict.fromkeys(mylist) will remove the duplicates from a list preserving the original order of the list.

items = [1, 2, 0, 1, 3, 2]
list(dict.fromkeys(items))

[1, 2, 0, 3]

Alternatively, unpacking can be used

items = [1, 2, 0, 1, 3, 2]
[*dict.fromkeys(items)]

[1, 2, 0, 3]

To remove the duplicates from a list and the original order of the list need not be preserved, assigning the list to a set and then converting it back to list will remove all the duplicates from the list (sets will not necessarily maintain the order of a list)

items = [1, 2, 0, 1, 3, 2]
list(set(items))

[0, 1, 2, 3]
