Sometimes, we want to create an ordered set with Python.
In this article, we’ll look at how to create an ordered set with Python.
How to create an ordered set with Python?
To create an ordered set with Python, we can create a list from dict keys.
For instance, we write
keywords = ['foo', 'bar', 'bar', 'foo', 'baz', 'foo']
l = list(dict.fromkeys(keywords))
to get a dict with keys created from the keywords list.
And then we can convert the dict returned to a list with list.
As a result, we get ['foo', 'bar', 'baz'] as the value of l.
Conclusion
To create an ordered set with Python, we can create a list from dict keys.
