我想对csv文件（A到Z）的数据进行排序。但它显示错误

Question

我的代码是

import sys
import csv
import operator
data = csv.reader(open("clean.csv","r"))
sortedlist = sorted(data, key=operator.itemgetter(0))
with open("Final42.csv", "w") as sorter:
    fileWriter = csv.writer(sorter)
    for row in sortedlist:
        fileWriter.writerow(row)

我收到错误 IndexError：列表索引超出范围
