本篇文章為大家展示了python中寫入excel的方法有哪些，內(nèi)容簡明扼要并且容易理解，絕對能使你眼前一亮，通過這篇文章的詳細(xì)介紹希望你能有所收獲。

首先使用openpyxl進(jìn)行寫入操作，代碼如下：

book = openpyxl.Workbook()
auths = Auth.objects.filter(owner_id=1)
filename = '導(dǎo)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(dǎo)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 += 1
return 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 += 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(jìn)，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 wbook
def xlsx(filename, rows_info, sheet='Result'):
if filename and sheet:
wb = wbook()
_sheet = wb.active
_sheet.title = sheet
row = _sheet.max_row
for 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 += 1
wb.save(filename)
else:
return '文件和sheet不能為空'
