How to remove duplicates from a list?

Method 1:   list(set(my_list))
Removes duplicates, but order is not preserved.

my_list = [1, 2, 2, 3, 1]
unique_list = list(set(my_list))
print(unique_list)  # Output: [1, 2, 3] (order may change)

Method 2:   list(dict.fromkeys(my_list))
Removes duplicates and keeps original order.

my_list = [1, 2, 2, 3, 1]
unique_list = list(dict.fromkeys(my_list))
print(unique_list)  # Output: [1, 2, 3]
