Solve the following python programming problem given the following code:
@ pytest.fixture 
def iter_fixture(self, request, package_) : 
    def rel(is_external, reltype) : 
        part = instance_mock (request, Part) 
        return instance_mock (request, _Relationship, is_external = is_external, reltype = reltype, target_part = part) 
rels = (rel (True, RT.IMAGE), rel (False, RT.SLIDE), rel (False, RT.IMAGE)) 
    package_.iter_rels.return_value = iter ((rels [0], rels [1], rels [2], self [2])) 
    image_parts = _ImageParts (package_) 
    expected_parts = [rels [2].target_part] 
    return (image_parts, expected_parts) 

    
    

    Fix the buggy line: package_.iter_rels.return_value = iter ((rels [0], rels [1], rels [2], self [2]))
assistant
#Here is Python program to fix the buggy line: package_.

package_.iter_rels.return_value = iter ((rels [0], rels [1], rels [2], rels [2]))
