| |
| Native set operations |
| ====================== |
| |
| These ``set`` operations have fast, optimized implementations. Other |
| set operations use generic implementations that are often slower. |
| |
| Construction |
| ------------ |
| |
| Construct set with specific items: |
| |
| * ``{item0, ..., itemN}`` |
| |
| Construct empty set: |
| |
| * ``set()`` |
| |
| Construct set from iterable: |
| |
| * ``set(x: Iterable)`` |
| |
| Set comprehensions: |
| |
| * ``{... for ... in ...}`` |
| * ``{... for ... in ... if ...}`` |
| |
| Operators |
| --------- |
| |
| * ``item in s`` |
| |
| Methods |
| ------- |
| |
| * ``s.add(item)`` |
| * ``s.remove(item)`` |
| * ``s.discard(item)`` |
| * ``s.update(x: Iterable)`` |
| * ``s.clear()`` |
| * ``s.pop()`` |
| |
| Functions |
| --------- |
| |
| * ``len(s: set)`` |
