      Description copied from class: `PySequence`
      Returns the element of the sequence at the given index. This is an extension point called by PySequence in its implementation of `PySequence.__getitem__(org.python.core.PyObject)` It is guaranteed by PySequence that when it calls `pyget(int)` the index is within the bounds of the array. Any other clients must make the same guarantee.

      Returns:
        the element at the given position in the list.

      Description copied from class: `PySequence`
      Sets the indexed element of the sequence to the given value. This is an extension point called by PySequence in its implementation of `PySequence.__setitem__(int, org.python.core.PyObject)` It is guaranteed by PySequence that when it calls pyset(int) the index is within the bounds of the array. Any other clients must make the same guarantee.
      Parameters:
        `index` - index of the element to set.

      Description copied from interface: `Traverseproc`
      Traverses all directly contained `PyObject`s. Like in CPython, `arg` must be passed unmodified to `visit` as its second parameter. If `Visitproc.visit(PyObject, Object)` returns nonzero, this return value must be returned immediately by traverse. `Visitproc.visit(PyObject, Object)` must not be called with a `null` PyObject-argument.
      Specified by:
        `traverse` in interface `Traverseproc`

      Description copied from interface: `Traverseproc`
      Optional operation. Should only be implemented if it is more efficient than calling `Traverseproc.traverse(Visitproc, Object)` with a visitproc that just watches out for `ob`. Must return `false` if `ob` is `null`.
      Specified by:
        `refersDirectlyTo` in interface `Traverseproc`
      Throws:
        `java.lang.UnsupportedOperationException`
