我继续得到indexerror：python上的索引列表超出范围

Question

if productid==row[0]: #This means it runs every row in the reader file which is the csv file in this case
    price = row[2]
    stocklevel = row[3]
    reorderlevel = row[4]
    targetlevel = row[5]
    total = float(amount)*float(price)
    totalprice = float(totalprice)+float(total)
    stocklevel = float(stocklevel)-float(amount)
    newstock = (stocklevel)
    b = open('products.csv', 'w')
    a = csv.writer(b)
    data = [['row[3]', 'row[4]', 'row[5]'],
           ['293', '219'],
           ['54', '13']]
    a.writerows(data)
    b.close()

基本上我一直收到此错误文件

  

＆＃34; E：\ Python Program \ pythonv5.py＆＃34;，第71行，in       productlist（）文件＆＃34; E：\ Python Program \ pythonv5.py＆＃34;，第9行，在产品列表中       print（row [0] +＆＃34;＆＃34; + row [1] +＆＃34;＆＃34; + row [2]）IndexError：列表索引超出范围

Answer 1

尝试：

if len(row) > 0 and productid==row[0]:
   #rest of the code here ...

您需要确保行列表具有要编制索引的长度。
