python各种excel写入方式速度比较

经过实验，新建一个excel表格，该表格拥有7个sheet，每个sheet有800条数据，其中最后一个sheet为空。

首先使用openpyxl进行写入操作，代码如下：

book = openpyxl.Workbook()
auths = Auth.objects.filter(owner_id=1)
filename = '导出数据'
for auth in auths:
    sheet = book.create_sheet(auth.name, index = 0)
    sheet.append([
            _("书名"),
            _("作者"),
            _("译者"),
            _("出版社"),
            _("序列号"),
            _("总页数"),
        ])
    objs = None
    objs = Book.objects.filter(owner_id=auth.id)
    for u in objs:
        data = []
        data.append(u.name)
        data.append(auth.name)
        data.append(u.translator)
        data.append(u.press)
        data.append(u.serializer)
        data.append(u.page)
        sheet.append(data)
return ExcelBookResponse(book, filename)

使用xlwt写入数据：

book = xlwt.Workbook()
auths = Auth.objects.filter(owner_id=1)
filename = '导出数据'
for auth in auths:
    sheet = book.add_sheet(sensor.name)
    sheet.write(0, 0, _("书名"))
    sheet.write(0, 1, _("作者"))
    sheet.write(0, 2, _("译者"))
    sheet.write(0, 3, _("出版社"))
    sheet.write(0, 4, _("序列号"))
    sheet.write(0, 5, _("总页数"))
    i = 1
    objs = None
    objs = Book.objects.filter(owner_id=auth.id)
    for u in objs:
        sheet.write(i, 0, u.name)
        sheet.write(i, 1, auth.name)
        sheet.write(i ,2,u.translator)
        sheet.write(i ,3,u.press)
        sheet.write(i, 4, u.serializer)
        sheet.write(i, 5, u.page)
        i += 1
return ExcelBookResponse(book, filename)

使用XlsxWriter写入数据：
 

book = xlsxwriter.Workbook(output)
auths = Auth.objects.filter(owner_id=1)
for auth in auths:
    sheet = book.add_worksheet(sensor.name)
    header = [
            _("书名"),
            _("作者"),
            _("译者"),
            _("出版社"),
            _("序列号"),
            _("总页数"),
        ]
    sheet.write_row("A1", header)
    objs = Book.objects.filter(owner_id=auth.id)
    i = 1
    for u in objs:
        sheet.write(i, 0, u.name)
        sheet.write(i, 1, auth.name)
        sheet.write(i ,2,u.translator)
        sheet.write(i ,3,u.press)
        sheet.write(i, 4, u.serializer)
        sheet.write(i, 5, u.page)
        i += 1
book.close()
file_ext = 'xlsx'
mimetype = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
# self['Content-Disposition'] = 'attachment; filename*=UTF-8\'\'"{2}.{1}"; filename="{0}.{1}"'.format(filename.replace('"', '\"'), file_ext, urllib.parse.quote(filename.replace('"', '\"'))).encode('utf8')
return HttpResponse(content=output.getvalue(), content_type=mimetype)

三者的时间比较（两种方式的文件内容是一样的）：

openpyxl: 文件大小为110.75kb, 平均时间大约为570ms

xlwt: 文件大小为505.91kb，平均时间大约为440ms

XlsxWrite: 文件大小为109.28kb，平均时间大约为500ms

xlwt写入的行数有限制，因此对于较大的文件来说，XlsxWrite的速度较快一点
