请问这段代码和我预期的结果不太一样，求大神帮忙看一下，谢谢。哪里的问题？

Question

主要想实现分离excel数据，将数据按每500条分成一个sheet。但每次分离出来的数据虽然是500条，但第二个sheet第一个元素不是从第501开始，而是第50个开始的。详情看图

import os
import xlrd
import xlwt
from pip._vendor.distlib.compat import raw_input

# limit = raw_input('input limit number:')
limit = 500
readbook=r'D:\a\a.csv'
savebook=r'D:\b\bb.csv'
# readbook = raw_input('input excel read path:')
#
# savebook = raw_input('input excel save path:')

if limit == '':
    limit = 50  # 默认按100条拆分
print ('拆分数量: ' + str(limit))

limit = int(limit)

# '/Users/huqiang/Desktop/shoplist.xls'

data = xlrd.open_workbook(readbook)
# 获取sheet
table = data.sheets()[0]
# 行数
nrows = table.nrows
print(nrows)
# 列数
ncols = table.ncols
if nrows % limit != 0:
    sheets = (nrows // limit)+1
else:
    sheets=nrows // limit
# sheets = (nrows // limit)+1
print(sheets)
# print str(nrows) + '   ' + str(ncols)

# print table10.cell(nrows - 1, ncols - 1).value

workbook = xlwt.Workbook(encoding='ascii')

for i in range(0, int(sheets)):
    print('**',i)
    worksheet = workbook.add_sheet(str(i))
    for row in range(0, limit+1):![图片说明](https://img-ask.csdn.net/upload/201910/30/1572398082_764150.jpg)

        # print(row)
        row_content = table.row_values(row + (i*50))
        for col in range(0, ncols):
                worksheet.write(row, col, row_content[col])
workbook.save(savebook)

就在你的代码基础上改了，写代码要把临界条件考虑完全

# -*- coding: UTF-8 -*-
import os
import xlrd
import xlwt
from pip._vendor.distlib.compat import raw_input

# limit = raw_input('input limit number:')
limit = 500
readbook=r'D:\a\a.csv'
savebook=r'D:\b\bb.csv'
# readbook = raw_input('input excel read path:')
#
# savebook = raw_input('input excel save path:')

if limit == '':
    limit = 50  # 默认按100条拆分
print ('拆分数量: ' + str(limit))

limit = int(limit)

# '/Users/huqiang/Desktop/shoplist.xls'

data = xlrd.open_workbook(readbook)
# 获取sheet
table = data.sheets()[0]
# 行数
nrows = table.nrows
print(nrows)
# 列数
ncols = table.ncols
if nrows % limit != 0:
    sheets = (nrows // limit)+1
else:
    sheets=nrows // limit
# sheets = (nrows // limit)+1
print('sheets:',sheets)
# print str(nrows) + '   ' + str(ncols)

# print table10.cell(nrows - 1, ncols - 1).value

workbook = xlwt.Workbook(encoding='ascii')

for i in range(0, int(sheets)):
    print('**',i)
    worksheet = workbook.add_sheet(str(i))
    if sheets-1 == i:
        for row in range(i*500, nrows):
            # print(row)
            row_content = table.row_values(row)
            for col in range(0, ncols):
                    worksheet.write(row-i*500, col, row_content[col])
    else:
        for row in range(0, limit):
            # print(row)
            row_content = table.row_values(row + (i*500))
            for col in range(0, ncols):
                    worksheet.write(row, col, row_content[col])

workbook.save(savebook)
