文がすべての条件に対して1つの出力しか生成しない場合

Question

私は、pythonでデコレータを使用して複数の集約関数を実行しています。

これらのifの条件は、異なる値の1つの条件に対してのみ出力を生成します。

私は位置を変更しようとしましたが、常に同じ出力を生成しています。

私は間違っていますか？

はどうすれば条件での私の要件に従って値が異なることができます

サンプルコード：

      etc.

      return op(self(x), operand(x))

    return function_op

       and Balance > 2500): 
       balance = 1 
      else: 
       balance = 2 



     def feat_list(): 
      total = getAge + getEducation + getEmployment + getStability +

      return total 



     if feat_list() <= 11: 
      customer.Service_Level = Service.objects.get(service_name = 
       'Silver Package') 
      silver_customers.append(customer.Name) 

     elif 11 < feat_list() <= 15: 
      customer.Service_Level = Service.objects.get(service_name = 
       'Gold Package') 
      gold_customers.append(customer.Name) 
     elif feat_list() > 15: 
      customer.Service_Level = Service.objects.get(service_name = 
       "Platinum Package") 
      platinum_customers.append(customer.Name) 
     else: 
      customer.Service_Level = Service.objects.get(service_name = "No 
       Service Package") 
      non_customers.append(customer.name) 

     customer.save() 

     if platinum_customers: 
      message = 'The following customers are now Platinum Customers: 
       {}'.format(', '.join(platinum_customers)) 
     if silver_customers: 
      message = 'The following customers are now Silver Customers: 
       {}'.format(', '.join(silver_customers)) 
     if gold_customers: 
      message = 'The following customers are now Gold Customers: 
       {}'.format(', '.join(gold_customers)) 
     if not platinum_customers and not silver_customers and not   
       gold_customers: 
      message = 'No customer changes made!' 
     ModelAdmin.message_user(request, message, level=SUCCESS) 
    allocate_service.short_description = 'Allocate Service' 

私はService Levelの値を決定するために、このコードのセクションを実行したいと思います：

if feat_list() <= 11: 
     customer.Service_Level = Service.objects.get(service_name = 'Silver Package') 
     silver_customers.append(customer.Name) 

    elif 11 < feat_list() <= 15: 
     customer.Service_Level = Service.objects.get(service_name = 'Gold Package') 
     gold_customers.append(customer.Name) 
    elif feat_list() > 15: 
     customer.Service_Level = Service.objects.get(service_name = "Platinum Package") 
     platinum_customers.append(customer.Name) 
    else: 
     customer.Service_Level = Service.objects.get(service_name = "No Service Package") 
     non_customers.append(customer.name) 

    customer.save() 

問題はそれも設定され、すべてのクエリにSilver PackagesのService Levelを与えているということです私が習慣を持っていたら、Platinum or Gold Packagesを得るためにいくつか編集しました。私はこのブロックで何が正確に間違っているのか分かりません。それは望ましくない出力を提供していますが、実行中です

Answer 1

私は、各機能にデコレータを使用する必要があります。

1. はあなたが
2. あなたはリターン各サブ操作の結果に必要な評価されている各機能にデコレータを追加する必要があります（あなたがfeat_listでそれを合計することができます（））

となっています。そのため、11以下のスコアを受け取ったため、最終的にsilver_customersになりました。結果を追跡することは容易であるので、 合計変数を印刷することが重要である：
