### Branch length using python

I have written a code for the finding branch length as

for m in range(len(frombus)): err10, rval = psspy.brndat(frombus[m],tobus[m],Branchid[m],'LENGTH') # Short the line from Transformer by using 'Length' because Line has length transformer has no length Busval=frombus[m]#if str(rval)>0: BUSval1.append(Busval) linlen.append(rval) if rval>0.0: frombus1.append(frombus[m]) tobus1.append(tobus[m]) Branchid1.append(Branch_id[m]) linlen1.append(rval)

I work for psse 33.4 but not working in PSSE 34.4 . How can I solve the issue. After debugging I found rval returning value for PSSS 33.4 but in case of PSSE 34.4 returning no value
