- [section boost_python_list.hpp]
- [section Introduction]
- Exposes a [link concepts.objectwrapper.typewrapper_concept_requirements TypeWrapper] for the Python [@http://www.python.org/doc/current/lib/typesseq-mutable.html list] type.
- [endsect]
- [section Class `list`]
- Exposes the [@http://www.python.org/doc/current/lib/typesseq-mutable.html mapping protocol] of Python's built-in `list` type. The semantics of the constructors and member functions defined below can be fully understood by reading the [link concepts.objectwrapper.typewrapper_concept_requirements TypeWrapper] concept definition. Since `list` is publicly derived from [link object_wrappers.boost_python_object_hpp.class_object `object`], the public `object` interface applies to `list` instances as well.``
