經(jīng)過實驗，新建一個excel表格，該表格擁有7個sheet，每個sheet有800條數(shù)據(jù)，其中最后一個sheet為空。

首先使用openpyxl進行寫入操作，代碼如下：

book = openpyxl.Workbook()auths = Auth.objects.filter(owner_id=1)filename = ’導出數(shù)據(jù)’for auth in auths: sheet = book.create_sheet(auth.name, index = 0) sheet.append([ _('書名'), _('作者'), _('譯者'), _('出版社'), _('序列號'), _('總頁數(shù)'), ]) 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寫入數(shù)據(jù)：

book = xlwt.Workbook()auths = Auth.objects.filter(owner_id=1)filename = ’導出數(shù)據(jù)’for auth in auths: sheet = book.add_sheet(sensor.name) sheet.write(0, 0, _('書名')) sheet.write(0, 1, _('作者')) sheet.write(0, 2, _('譯者')) sheet.write(0, 3, _('出版社')) sheet.write(0, 4, _('序列號')) sheet.write(0, 5, _('總頁數(shù)')) 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 += 1return ExcelBookResponse(book, filename)

使用XlsxWriter寫入數(shù)據(jù)：

book = xlsxwriter.Workbook(output)auths = Auth.objects.filter(owner_id=1)for auth in auths: sheet = book.add_worksheet(sensor.name) header = [ _('書名'), _('作者'), _('譯者'), _('出版社'), _('序列號'), _('總頁數(shù)'), ] 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 += 1book.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)

三者的時間比較（兩種方式的文件內(nèi)容是一樣的）：

openpyxl: 文件大小為110.75kb, 平均時間大約為570ms

xlwt: 文件大小為505.91kb，平均時間大約為440ms

XlsxWrite: 文件大小為109.28kb，平均時間大約為500ms

xlwt寫入的行數(shù)有限制，因此對于較大的文件來說，XlsxWrite的速度較快一點

補充知識：python寫入excel文件太慢如何解決-python往excel寫入大量數(shù)據(jù)

目前用的openpyxl，從數(shù)據(jù)庫獲取8W行的數(shù)據(jù)通過openpyxl寫入excel，要花費接近8分鐘，這也太慢了，用kettle的插件秒進，python有什么方法能提升速度么，或者openpyxl能批量插入么，按行效率太低了

#!/usr/bin/python# -*- coding: UTF-8 -*-from openpyxl import Workbook as wbookdef xlsx(filename, rows_info, sheet=’Result’):if filename and sheet:wb = wbook()_sheet = wb.active_sheet.title = sheetrow = _sheet.max_rowfor line in rows_info:if isinstance(line, str):row_list = [line]elif isinstance(line, dict):row_list = list(line.values())else:try:row_list = list(line)except:row_list = []for col in range(0, len(row_list)):col_info = row_list[col]_sheet.cell(row, col + 1, col_info)row += 1wb.save(filename)else:return ’文件和sheet不能為空’

以上這篇python各種excel寫入方式的速度對比就是小編分享給大家的全部內(nèi)容了，希望能給大家一個參考，也希望大家多多支持好吧啦網(wǎng)。
