Python: Remove duplicate list items with a set

Date: 2019-10-14 | python | list | duplicates | set | tutorial |


In my Python program I have a list containing duplicate elements. How can I easily get rid of those duplicates?


There are tons of possible ways to do this, but one simple way to dedupe a list is to use an intermediate set. Here's an example:

list_with_duplicates = [ "a", "b", "a"]
set_without_duplicates = set(list_with_duplicates)
list_without_duplicates = list(set_without_duplicates)


did this help?
