Python csv reader

[Yx37412]

最近学习写Python
我在读取文件夹下所有CSV档然后根据关键字整理，放入新的CSV档中
我写完以后发现一个BUG，一旦有一个CSV档里没有关键字，就无法执行
我想解掉这个BUG，但不知道怎么判断这句话 data.append(row[str(k_1)])
请求指导！谢谢大家！

if __name__ == "__main__":
    b = FileFilt()
    c = os.getcwd()
    print c
    b.FindFile(dirr = c)
    print(b.counter)
    d=[]
    i = 1
    for k in b.fileList:
        print k
        d.append(k)

    keyword=[]
    read_config(keyword)
    csvfile2 = file("good.csv",'wb')
    writer = csv.writer(csvfile2)
    writer.writerow(keyword)

    for i in range(1,len(d)):
        with open(d[2]) as csvfile:
            reader = csv.DictReader(csvfile)
            for row in reader:
                data=[]
                for k_1 in keyword:
                    data.append(row[str(k_1)])
                writer.writerow(data)
    csvfile2.close()
