Can't make a set from a list with repeated items and keep the items order.Does anyone know how to make an ordered set in Python?

Question

Ordered Set in Python

Answer 1

It can be also done with a simple for loop or with a comprehension:

res = []
[res.append(i) for i in mylist if i not in res]
print(res)
#output: ['blue', 'green', 'red', 'pink']

But the solution with dict should be preferred. This the case from python 3.7+. With older versions it does not work this way.

Answer 2

OK. Just found a way to emulate that using a dict, as it seems Python3 doesn't have ordered sets:

mylist =
['blue', 'blue', 'blue', 'green', 'green', 'red', 'red', 'pink']
mylist = list(dict.fromkeys(mylist).keys())

# This outputs:
['blue', 'green', 'red', 'pink']
