## Introduction

Exposes a TypeWrapper for the Python str type.

## Classes

### Class `str`

Exposes the string methods of Python's built-in `str` type. The semantics of the constructors and member functions defined below can be fully understood by reading the TypeWrapper concept definition. Since `str` is publicly derived from `object`, the public object interface applies to `str` instances as well.
