| Native tuple operations |
| ======================= |
| |
| These ``tuple`` operations have fast, optimized implementations. Other |
| tuple operations use generic implementations that are often slower. |
| |
| Unless mentioned otherwise, these operations apply to both fixed-length |
| tuples and variable-length tuples. |
| |
| Construction |
| ------------ |
| |
| * ``item0, ..., itemN`` (construct a tuple) |
| * ``tuple(lst: list)`` (construct a variable-length tuple) |
| * ``tuple(lst: Iterable)`` (construct a variable-length tuple) |
| |
| Operators |
| --------- |
| |
| * ``tup[n]`` (integer index) |
| * ``tup[n:m]``, ``tup[n:]``, ``tup[:m]`` (slicing) |
| |
| Statements |
| ---------- |
| |
| * ``item0, ..., itemN = tup`` (for fixed-length tuples) |
| |
| Functions |
| --------- |
| |
| * ``len(tup: tuple)`` |
