python - Data is saved including blank -

i wanna parse excel , put model(city&prefecture&area&user) . wrote

fourrows_transpose=list(map(list, zip(*fourrows))) val3 = sheet3.cell_value(rowx=0, colx=9) user3 = companyransaction.objects.filter(corporation_id=val3).first() if user3:         area = area.objects.filter(name="america").first()         pref = prefecture.objects.create(name="prefecture", area=area)         city = city.objects.create(name="city", prefecture=pref)         price= price.objects.create(city=city)          pref.name = fourrows_transpose[0][0]         pref.save()          transpose in fourrows_transpose[2:]:             if len(transpose) == 5:                 if "×" in transpose or "○" in transpose:                     city.name = transpose[1]                    city.save()                     price.upper1000 = transpose[2]                    price.from500to1000 = transpose[3]                    price.under500 = transpose[4]                    price.save() 

now db

my ideal db in name a,a,a,a,b,b,b,b,c . rally cannot understand why such db made. think position of writing

city.name = transpose[1] city.save() 

is wrong, wrote these code under price.save(),but same db made. wrong in code?how can fix this?
