将数据追加到数据框和列表索引超出范围

Question

我在下面编写的代码

try: 

    ser.isOpen()
    print("Serial is Open")
except:

    print("Eror")
    exit()
if (ser.isOpen()):

        ser.write('1'.encode('utf-8'))
        df= pd.DataFrame(columns=['x-axis','y-axis','z-axis'])
        while(1): 

            while(k<TIME_PERIODS):

                Raw_data= ser.readline()
                #print(Raw_data.decode('utf-8'))
                Data= Raw_data.decode('utf-8').split(',')
                df=df.append({'x-axis': Data[0],'y-axis': Data[1],'z-axis': Data[2]}, ignore_index=True)
                df
                k=k+1    
            k=0
            df= pd.drop('x-axis','y-axis','z-axis',axis=1)

else :

    print("cannot connect")

结果在这里

 20 Data= Raw_data.decode('utf-8').split(',')
---> 21df=df.append({'x-axis': Data[0],'y-axis': Data[1],'z-axis': Data[2]}, ignore_index=True)

 22                 df
 23                 k=k+1

  

IndexError：列表索引超出范围

请帮助我修复它
