A dead simple set that preserves insertion order, internally using the python’s 3.7 dict, which preserves order.
pip install ordered-set-37
This class subclasses and implements all the methods of MutableSet.
from ordered_set_37 import OrderedSet
x = OrderedSet([1, 2, -1, "bar"])
x.add(0)
assert list(x) == [1, 2, -1, "bar", 0]This library uses the typing system, so feel free to do:
x: OrderedSet[str] = OrderedSet(("foo", "bar"))
x.add(1) # type checkers won't like this as it is not a stringAs an extra, you can access a value by index (although the speed is at worst O(n)):
x = OrderedSet(["foo", "bar", "baz"])
assert x[1] == "bar"For obvious reasons, this library is only Python 3.7+ compatible.
Feel free to contribute, fork, etc.
