篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了python用xlwt写excel相关的知识,希望对你有一定的参考价值。
例一,普通写入:
# -*-coding: utf-8-*- import xlwt workbook = xlwt.Workbook() sheet = workbook.add_sheet(\'sheet 1\') sheet.write(0,1,\'test text\')#第0行第一列写入内容 workbook.save(\'test.xls\')
例二,把字典写入到excel中:
#!/usr/bin/python #coding: utf-8 import xlsxwriter #创建一个新的xlsx文件(如果原有同名文件会被覆盖) workbook = xlsxwriter.Workbook("Expenses01.xlsx") #创建一个新的表单,默认名称为 “sheet1”,输入字符参数可指定名称 worksheet = workbook.add_worksheet() expenses = { \'Rent\': 1000, \'Gas\' : 100, \'Food\': 300, \'Gym\' : 50, } #worksheet 默认是从0行、0列开始计数 row = 0 col = 0 #worksheet.write 方法将数据写入 xlsx 表格中 #参数依次为:行号、列号、数据、[格式] for item, cost in expenses.items(): worksheet.write(row, col , item) worksheet.write(row, col + 1, cost) row += 1 #显式关闭workbook,若不显式指定,则作用域结束后自动关闭 workbook.close()
例三:xlsxwriter 格式处理,将待添加数据转换成相应的格式,添加到 xlsx 文件中
先设置格式,使用方法:workbook.add_format
再指定格式写入,使用方法:worksheet.write_string
# -*- coding: utf-8 -*- from datetime import datetime import xlsxwriter workbook = xlsxwriter.Workbook(\'Expenses02.xlsx\') worksheet = workbook.add_worksheet() #设定格式,等号左边格式名称自定义,字典中格式为指定选项 #bold:加粗,num_format:数字格式 bold_format = workbook.add_format({\'bold\':True}) money_format = workbook.add_format({\'num_format\':\'$#,##0\'}) date_format =workbook.add_format({\'num_format\':\'mmmm d yyyy\'}) #将二行二列设置宽度为15(从0开始) worksheet.set_column(1, 1, 15) #用符号标记位置,例如:A列1行 worksheet.write(\'A1\', \'Item\', bold_format) worksheet.write(\'B1\', \'Cost\', bold_format) worksheet.write(\'C1\', \'Cost\', bold_format) expenses = ( [\'Rent\', \'2016-03-11\', 1000], [\'Gad\', \'2016-03-12\', 100], [\'Food\', \'2016-03-13\', 400], [\'Gym\', \'2016-03-14\', 50], ) row = 1 col = 0 for item, date_str, cost in (expenses): #将数据格式转化为Python datetime.datetime 格式 #之后用write_datetime方法录入日期格式 date = datetime.strptime(date_str, "%Y-%m-%d") #使用write_string方法,指定数据格式写入数据 worksheet.write_string(row, col, item) worksheet.write_datetime(row, col + 1, date, date_format) worksheet.write_number(row, col + 2, cost, money_format) row += 1 worksheet.write(row, 0, \'Total\', bold_format) worksheet.write(row, 1, \'=SUM(B2:B5)\', money_format) workbook.close()
例四,xlsxwriter 添加表格,在 xlsx 文件中添加表格:
#!/usr/bin/python #coding: utf-8 import xlsxwriter workbook = xlsxwriter.Workbook(\'chart.xlsx\') worksheet = workbook.add_worksheet() #新建图标对象 chart = workbook.add_chart({\'type\': \'column\'}) #向 excel 中写入数据,建立图标时要用到 data = [ [1, 2, 3, 4, 5], [2, 4, 6, 8, 10], [3, 6, 9, 12, 15], ] worksheet.write_column(\'A1\', data[0]) worksheet.write_column(\'B1\', data[1]) worksheet.write_column(\'C1\', data[2]) #向图表中添加数据,例如第一行为:将A1~A5的数据转化为图表 chart.add_series({\'values\': \'=Sheet1!$A$1:$A$5\'}) chart.add_series({\'values\': \'=Sheet1!$B$1:$B$5\'}) chart.add_series({\'values\': \'=Sheet1!$C$1:$C$5\'}) #将图标插入表单中 worksheet.insert_chart(\'A7\', chart) workbook.close()
效果:
例五,更多可用的单元格式对象(Format Class):
ecxel 中每一个单元,都有如下属性:字体(fonts)、颜色(colors)、模式(patterns)、边界(borders)、alignment、number formatting
设置属性:
format = workbook.add_format() #用对象接口设置格式属性 format.set_bold() format.set_font_color(\'red\') #用字典设置格式属性 property = { \'bold\': True, \'font_color\': \'red\' } format = workbook.add_format(property)
