Introduction

Exposes a TypeWrapper for the Python tuple type.

Classes

Class 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.

Class tuple synopsis

namespace boost { namespace python
{
   class tuple : public object
   {
      // tuple() -> an empty tuple
      tuple();

      // tuple(sequence) -> tuple initialized from sequence's items
      template <class T>
      explicit tuple(T const& sequence)
  };
}}

Functions

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).

Example

using namespace boost::python;
tuple head_and_tail(object sequence)
{
    return make_tuple(sequence[0],sequence[-1]);
}
