  • python xlrd,xlwt 读写excel文件

    python 读excel文件,需要xlrd库。下载地址:https://pypi.python.org/pypi/xlrd

    python 写excel文件,需要xlwt库。下载地址:https://pypi.python.org/pypi/xlwt/1.1.2

    下载后修改扩展名为rar, 解压后安装:

    安装成功后就可以引用了。如下代码:

    # -*- coding: utf-8 -*-
    import os
    import xlrd
    import xlwt
    import datetime

    ##################读excel文件##############################

    #打开Excel文件,参数:excelFile:Excel文件路径
    def open_Excel(excelFile):
      excelFile = unicode(excelFile, "utf8")
      if os.path.isfile(excelFile):
        try:

          return data
        except Exception,e:
          print str(e)

    '''往EXCEl单元格写内容,每次写一行sheet:页签名称;row:行内容列表;rowIndex:行索引;
    isBold:true:粗字段,false:普通字体'''
    def WriteSheetRow(sheet,rowValueList,rowIndex,isBold):
      i = 0
      style = xlwt.easyxf('font: bold 1') #粗字体

      #style = xlwt.easyxf('font: bold 1, color red;') #红色字体
      for svalue in rowValueList:
        strValue = unicode(str(svalue),'utf-8')
        if isBold:
          sheet.write(rowIndex,i,strValue,style)
        else:
          sheet.write(rowIndex,i,strValue)
        i = i + 1

    #根据索引获取Excel表格中的数据 参数:excelFile:Excel文件路径 ,by_index:表的索引

      table = data.sheets()[sheetIndex]
      nrows = table.nrows #行数
      ncols = table.ncols #列数
      cursor = getSqlCursor()
      for i in xrange(0,nrows):
        headCols = table.row_values(i) #某一行数据
        for a in headCols:
          print a

    #测试
    open_Excel_ByIndex("D:\test.xlsx",0)

    #根据名称获取Excel表格中的数据 参数:excelFile:Excel文件路径
    #sheetName:Sheet1名称
    def open_Excel_BySheetName(excelFile,sheetName):
      sheetName = unicode(sheetName, "utf8")
      data = open_Excel(excelFile)
      table = data.sheet_by_name(sheetName)
      nrows = table.nrows #行数

        for a in headCols:
          print a
    #测试
    open_Excel_BySheetName("D:\test.xlsx",'sheet1')

    ##################写excel文件##############################
    '''写excel文件''' 
    def save_Excel(strFile):
      excelFile = unicode(strFile, "utf8")
      wbk = xlwt.Workbook()
      sheet = wbk.add_sheet('sheet1')

        WriteSheetRow(sheet,valueList,rowIndex,False)
      wbk.save(excelFile)

    #测试
    save_Excel("D:\test.xlsx")

    结果如下:

     ##################单元格常用设置##############################

    1、设置超链接

      #设置超链接
      

      font = xlwt.Font() # Create Font
      font.colour_index = 4 # 蓝色字体
      font.underline=True
      style = xlwt.XFStyle()
      style.font = font
      sheet.write(rowIndex,4,xlwt.Formula('HYPERLINK("https://www.baidu.com";"baidu")'),style)

    2、设置单元格背景色 

      #设置单元格背景色
      pattern = xlwt.Pattern()
      pattern.pattern = xlwt.Pattern.SOLID_PATTERN
      pattern.pattern_fore_colour = 5 #黄色
      style = xlwt.XFStyle()
      style.pattern = pattern
      sheet.write(5, 5, 'Cell Contents', style)
      ''' 颜色值
      0 = Black, 1 = White, 2 = Red, 3 = Green, 4 = Blue,
      5 = Yellow, 6 = Magenta, 7 = Cyan, 16 = Maroon,
      17 = Dark Green, 18 = Dark Blue, 19 = Dark Yellow ,
      20 = Dark Magenta, 21 = Teal,
      22 = Light Gray, 23 = Dark Gray
      '''

    3、设置粗字体

      style = xlwt.easyxf('font: bold 1')

      sheet.write(5, 5, 'Cell Contents', style)

    4、设置字体颜色

      style = xlwt.easyxf('font: bold 0, color red;')#红色字体

      sheet.write(5, 5, 'Cell Contents', style)

    5、设置列宽带

      sheet.col(1).width = 3333 # 3333 = 1" (one inch)

    6、设置日期格式

      style = xlwt.XFStyle()
      style.num_format_str = 'YYYY/MM/DD h:mm:ss' 
      sheet.write(5, 5, datetime.datetime.now(), style)

      


      #Other options: D-MMM-YY, D-MMM, MMM-YY, h:mm, h:mm:ss, h:mm, h:mm:ss,
      # M/D/YY h:mm, mm:ss, [h]:mm:ss, mm:ss.0

     7、合并行和列

      sheet.write_merge(0, 0, 0, 3, 'First Merge') 

      sheet.write_merge(2, 4, 0, 3, 'Second Merge')

      

     8、给单元格增加边框 

      borders = xlwt.Borders() # Create Borders
      borders.left = xlwt.Borders.DASHED

      # May be: NO_LINE, THIN, MEDIUM, DASHED, DOTTED, THICK, DOUBLE, HAIR, MEDIUM_DASHED,   THIN_DASH_DOTTED,              #MEDIUM_DASH_DOTTED, THIN_DASH_DOT_DOTTED, MEDIUM_DASH_DOT_DOTTED,

      #SLANTED_MEDIUM_DASH_DOTTED, or 0x00 through 0x0D.
      borders.right = xlwt.Borders.DASHED
      borders.top = xlwt.Borders.DASHED
      borders.bottom = xlwt.Borders.DASHED
      borders.left_colour = 0x40
      borders.right_colour = 0x40
      borders.top_colour = 0x40
      borders.bottom_colour = 0x40
      style = xlwt.XFStyle() # Create Style
      style.borders = borders # Add Borders to Style

      

    9、设置单元格中内容中位置,居中,局左右等

      alignment = xlwt.Alignment() # Create Alignment
      # May be: HORZ_GENERAL, HORZ_LEFT, HORZ_CENTER, HORZ_RIGHT,
      #HORZ_FILLED, HORZ_JUSTIFIED, HORZ_CENTER_ACROSS_SEL, HORZ_DISTRIBUTED
      alignment.horz = xlwt.Alignment.HORZ_CENTER   #水平居中
      # May be: VERT_TOP, VERT_CENTER, VERT_BOTTOM, VERT_JUSTIFIED, VERT_DISTRIBUTED
      alignment.vert = xlwt.Alignment.VERT_CENTER    #垂直居中
      style = xlwt.XFStyle() # Create Style
      style.alignment = alignment # Add Alignment to Style
      sheet.write(5, 5, 'Cell Contents', style)
