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

make_tuple
namespace boost { namespace python { tuple make_tuple(); template <class A0> tuple make_tuple(A0 const& a0); template <class A0, class A1> tuple make_tuple(A0 const& a0, A1 const& a1); ... template <class A0, class A1,...class An> tuple make_tuple(A0 const& a0, A1 const& a1,...An const& an); }}Constructs a new tuple object composed of
object(a0),
object(a0),...object(an)
.
