This #Shorts video contains a python3 trick to remove duplicates from a list.

----
#Our list is:
my_list = [ 1, 1, 2, 2, 3, 4, 5 ]

Python sets do not support duplicate items, so we convert the list into a set
my_list = set(my_list)

Now if you check the contents of my_list, it's a set represented by curly braces '{' '}'
{ 1, 2, 3, 4, 5}

and finally we convert back the set into a list:
my_list = list(my_list)

which gives us
[ 1, 2, 3, 4, 5 ]
----
This can also done using one line of code:
my_list = [ 1, 1, 2, 2, 3, 4, 5 ]
my_list = list(set(my_list))
