i cutted it down

=====
class EnumSectionContentType(object):
    DATABYTE = 2
    DATADOUBLEWORD = 3
    DATAWORD = 4
#LABEL = 0

def _getStringOfElements(elements):
    objectFileString = ""

    elements = [{'type': 2, 'data': {'elements': ['83H', '0FAH', '9AH', '27H', '81H', '49H', '0CEH', '11H']}}]

    for iterationElement in elements:
        objectFileString += "INSIDE1 "
        
        if iterationElement["type"] == EnumSectionContentType.LABEL:
            objectFileString +=  iterationElement["data"]["labelname"] + ":" + "\n"
        elif iterationElement["type"] == EnumSectionContentType.DATABYTE:
            objectFileString += "INSIDE" + "\n"

            if   iterationElement["type"] == EnumSectionContentType.DATADOUBLEWORD:
                objectFileString += objectFileString + "dd "
            elif iterationElement["type"] == EnumSectionContentType.DATABYTE:
                objectFileString += objectFileString + "db "

    return objectFileString

print(_getStringOfElements(None))

I don't expect any output, I expect a exception (because LABEL is not defined)

but hell no...
