| Native string operations |
| ======================== |
| |
| These ``str`` operations have fast, optimized implementations. Other |
| string operations use generic implementations that are often slower. |
| |
| Construction |
| ------------ |
| |
| * String literal |
| * ``str(x: int)`` |
| * ``str(x: object)`` |
| |
| Operators |
| --------- |
| |
| * Concatenation (``s1 + s2``) |
| * Indexing (``s[n]``) |
| * Slicing (``s[n:m]``, ``s[n:]``, ``s[:m]``) |
| * Comparisons (``==``, ``!=``) |
| * Augmented assignment (``s1 += s2``) |
| |
| Methods |
| ------- |
| |
| * ``s1.endswith(s2: str)`` |
| * ``s.join(x: Iterable)`` |
| * ``s.replace(old: str, new: str)`` |
| * ``s.replace(old: str, new: str, count: int)`` |
| * ``s.split()`` |
| * ``s.split(sep: str)`` |
| * ``s.split(sep: str, maxsplit: int)`` |
| * ``s1.startswith(s2: str)`` |
