Solve the following python programming problem given the following code:
def determine_result(self, returncode, returnsignal, output, isTimeout) : 
    def sanitizeXML(s) : 
        return s.replace ('<>', '<emptyTag>').replace ('</>', '</emptyTag>') 
if ((returnsignal == 0) and ((returncode == 0) or (returncode == 10))) : 
        try : 
            tree = ET.fromstringlist (map (sanitizeXML, output)) 
            status = tree.findtext ('cprover-status') 
            if (status is None) : 
                def isErrorMessage(msg) : 
                    return (msg.get ('type', None) == 'ERROR') 
messages = list (filter (isErrorMessage, tree.getiterator ('message'))) 
                if messages : 
                    msg = messages [0].findtext ('text') 
                    if (msg == 'Out of memory') : 
                        status = 'OUT OF MEMORY' 
else : 
                        if msg : 
                            status = 'ERROR ({0})'.format (returncode) 
else : 
                            status = 'ERROR' 
else : 
                    status = 'INVALID OUTPUT' 
else : 
                if (status == 'FAILURE') : 
                    assert (returncode == 10) 
                    reason = tree.find ('goto_trace').find ('failure').findtext ('reason') 
                    if (not reason) : 
                        reason = tree.find ('goto_trace').find ('failure').get ('reason') 
if ('unwinding assertion' in reason) : 
                        status = result.RESULT_UNKNOWN 
else : 
                        status = result.RESULT_FALSE_REACH 
else : 
                    if (status == 'SUCCESS') : 
                        assert (returncode == 0) 
                        if ('--no-unwinding-assertions' in self.options) : 
                            status = result.RESULT_UNKNOWN 
else : 
                            status = result.RESULT_TRUE_PROP 
except Exception : 
            if isTimeout : 
                status = 'TIMEOUT' 
else : 
                if ('Minisat::OutOfMemoryException' in output) : 
                    status = 'OUT OF MEMORY' 
else : 
                 ...

    
    

    Fix the buggy line: status = 'ERROR ({0})'.format (returncode)

#Here is Python program to find ('goto_trace').

status = 'ERROR ({0})'.format (msg)
