Are sets ordered like dicts in python3.6

Question

Due to changes in dict implementation in Python 3.6 it is now ordered by default. Do sets preserve order as well now?

I could not find any

Answer 1

sets are not ordered in Python 3.6, not even as a CPython implementation detail. A simple example illustrates this:

>>> import string
>>> string.digits
'0123456789'
>>> set(string.digits)
{'7', '0', '2', '8', '6', '9', '1', '5', '4', '3'}

The Python 3 docs are clear on this:

A set is an unordered collection with no duplicate elements.
