| |
| Native list operations |
| ====================== |
| |
| These ``list`` operations have fast, optimized implementations. Other |
| list operations use generic implementations that are often slower. |
| |
| Construction |
| ------------ |
| |
| Construct list with specific items: |
| |
| * ``[item0, ..., itemN]`` |
| |
| Construct empty list: |
| |
| * ``[]`` |
| * ``list()`` |
| |
| Construct list from iterable: |
| |
| * ``list(x: Iterable)`` |
| |
| List comprehensions: |
| |
| * ``[... for ... in ...]`` |
| * ``[... for ... in ... if ...]`` |
| |
| Operators |
| --------- |
| |
| * ``lst[n]`` (get item by integer index) |
| * ``lst[n:m]``, ``lst[n:]``, ``lst[:m]``, ``lst[:]`` (slicing) |
| * ``lst * n``, ``n * lst`` |
| * ``obj in lst`` |
| |
| Statements |
| ---------- |
| |
| Set item by integer index: |
| |
| * ``lst[n] = x`` |
| |
| For loop over a list: |
| |
| * ``for item in lst:`` |
| |
| Methods |
| ------- |
| |
| * ``lst.append(obj)`` |
| * ``lst.extend(x: Iterable)`` |
| * ``lst.insert(index, obj)`` |
| * ``lst.pop(index=-1)`` |
| * ``lst.remove(obj)`` |
| * ``lst.count(obj)`` |
| * ``lst.index(obj)`` |
| * ``lst.reverse()`` |
| * ``lst.sort()`` |
| |
| Functions |
| --------- |
| |
| * ``len(lst: list)`` |
