Solve the following python programming problem given the following code:
@ mock_streams ('stdout') 
def test_global_parallel_honors_runs_once() : 
    '
    fab -P (or env.parallel) should honor @runs_once
    ' 
    @ decorators.runs_once 
    def mytask() : 
        print ('yolo') 
with settings (hide ('everything'), parallel = True) : 
        execute (result, hosts = ['localhost', '127.0.0.1']) 
result = sys.stdout.getvalue () 
    eq_ (result, 'yolo
') 
    assert (result != 'yolo
yolo
') 

    
    

    Fix the buggy line: execute (result, hosts = ['localhost', '127.0.0.1'])
