Solve the following python programming problem given the following code:
def _serialiseServices(self, jobStore, jobWrapper, rootJobWrapper) : 
    '
        Serialises the services for a job.
        ' 
    def processService(service, serviceJob, depth) : 
        if (depth == len (jobWrapper.services)) : 
            jobWrapper.services.append ([]) 
for (childService, childServiceJob) in service._childServices : 
            processService (childService, childServiceJob, (depth + 1)) 
serviceJobWrapper = serviceJob._createEmptyJobWrapperForJob (jobStore, predecessorNumber = 1) 
        serviceJobWrapper.startJobStoreID = jobStore.getEmptyFileStoreID () 
        serviceJobWrapper.terminateJobStoreID = jobStore.getEmptyFileStoreID () 
        serviceJobWrapper.errorJobStoreID = jobStore.getEmptyFileStoreID () 
        assert jobStore.fileExists (serviceJobWrapper.startJobStoreID) 
        assert jobStore.fileExists (serviceJobWrapper.terminateJobStoreID) 
        assert jobStore.fileExists (serviceJobWrapper.errorJobStoreID) 
        j = (serviceJobWrapper.jobStoreID, serviceJobWrapper.memory, serviceJobWrapper.cores, serviceJobWrapper.disk, serviceJobWrapper.startJobStoreID, serviceJobWrapper.terminateJobStoreID, serviceJobWrapper.errorJobStoreID) 
        jobWrapper.services [depth].append (j) 
        childServices = service._childServices 
        service._childServices = None 
        assert (serviceJob._services == []) 
        serviceJob._serialiseJob (jobStore, { 
            serviceJob : serviceJobWrapper, 
}, rootJobWrapper) 
        service._childServices = childServices 
for (service, serviceJob) in self._services : 
        processService (service, jobWrapper, 0) 
self._services = []
