Solve the following python programming problem given the following code:
@ patch ('pants.contrib.scrooge.tasks.thrift_linter.calculate_compile_sources') 
def test_lint(self, mock_calculate_compile_sources) : 
    def get_default_jvm_options() : 
        return self.task_type ().get_jvm_options_default (self.context ().options.for_global_scope ()) 
thrift_target = self.create_library ('a', 'java_thrift_library', 'a', ['A.thrift']) 
    task = self.create_task (self.context (target_roots = thrift_target)) 
    self._prepare_mocks (task) 
    expected_include_paths = { 'src/thrift/tweet', 'src/thrift/users' } 
    expected_paths = { 'src/thrift/tweet/a.thrift', 'src/thrift/tweet/b.thrift' } 
    mock_calculate_compile_sources.return_value = (expected_include_paths, self) 
    task._lint (thrift_target) 
    self._run_java_mock.assert_called_once_with (classpath = 'foo_classpath', main = 'com.twitter.scrooge.linter.Main', args = ['--ignore-errors', '--include-path', 'src/thrift/users', '--include-path', 'src/thrift/tweet', 'src/thrift/tweet/b.thrift', 'src/thrift/tweet/a.thrift'], jvm_options = get_default_jvm_options (), workunit_labels = ['COMPILER']) 

    
    

    Fix the buggy line: mock_calculate_compile_sources.return_value = (expected_include_paths, self)

#Here is Python code to fix the buggy line: mock_calculate_compile_sources.

mock_calculate_compile_sources.return_value = (expected_include_paths, expected_paths)
