       if i <= 121:         
           for j in range(6):             
               consumption = consumption + df2.loc[df2['Main Load [kWh]']]     
               pos = pos + 1         
            weekly_consumption=weekly_consumption.append(pos,consumption)         
            consumption = 0    
       else:        
           for j in range(1):             
               consumption = consumption + df2.loc[df2['Main Load [kWh]']]

           weekly_consumption=weekly_consumption.append(pos,consumption)         
           consumption = 0
