Python operates excel to read and write data

这次给大家带来python操作excel读写数据，python操作excel读写数据的注意事项有哪些，下面就是实战案例，一起来看一下。

本文实例为大家分享了python操作EXCEL的实例源码，供大家参考，具体内容如下

读EXCEL的操作：把excel的数据存储为字典类型

#coding=utf8

#导入读excel的操作库
import xlrd
class GenExceptData(object):
  def init(self):
    try:
      self.dataDic={}
      #打开工作薄
      self.wkbook= xlrd.open_workbook("Requirement.xls")
      #获取工作表“requirement”
      self.dataSheet=self.wkbook.sheet_by_name("requirement")
      #把数据按 按照相应格式写入excel表中
      self.readDataToDicl()
      #保存文件
    except Exception,e:
      print "Read Excel error:",e

  def readDataToDicl(self):
    try:
      nrows = self.dataSheet.nrows
      ncols = self.dataSheet.ncols

      print ncols ,nrows
      try:
        for rowNum in range(1,nrows):
              #把数据的当前行的元素与上一行元素作比较
              #如果不相等执行if语句
              try:

                singleJson={}
                propertyName=self.dataSheet.cell(rowNum,3).value
                propertyValue=self.dataSheet.cell(rowNum,4).value

                if self.dataSheet.cell(rowNum,0).value and self.dataSheet.cell(rowNum,2).value:
                  mdEvent=self.dataSheet.cell(rowNum,0).value
                  singleJson["serviceId"]=self.dataSheet.cell(rowNum,2).value
                singleJson[propertyName]=propertyValue
                print singleJson
                self.dataDic[mdEvent]=singleJson
                singleJson.clear()


              except Exception,e:
                print "Get Data Error:",e
      except Exception,e:
        print "Reading Data Error:",e
    except Exception,e:
      print "Reading Data TO Dic Error:",e




def test():
  GenExceptData()

if name=="main":
  test()

写EXCEL的操作：把csv文件的数据按照需求写入到excel文件中

#coding=utf8

from readCSV import readCSV
import xlwt

class GenTestCase():
  def init(self,path="E:\\PythonDemo\\OperExcel\\Demo.csv"):
    self.dataInfor=readCSV(path)
    #创建工作薄
    self.wkbook=xlwt.Workbook()
    #创建表:“埋点需求”
    self.dataSheet=self.wkbook.add_sheet("shellt")
    self.creatHead()

  def creatHead(self):
    firstLine=[]
    #创建表头
    for index in range(len(firstLine)):
      self.dataSheet.write(0,index,firstLine[index])

    dataBody=self.dataInfor.buffer
    print dataBody.len()
    currentrow=1
    for rowNum in range(1,len(dataBody)):
      for index in range(len(dataBody[rowNum])):
        if rowNum>1:
          if dataBody[rowNum-1][0]!=dataBody[rowNum][0] :
            print currentrow,rowNum
            if currentrow==1:
              for cols in range(3):
                cellValue=dataBody[currentrow][cols]
                cellValue=cellValue.decode("gbk")
                data=u"%s" %(cellValue)
                self.dataSheet.write_merge(currentrow,rowNum-1,cols,cols,data)

              for cols in range(6,13):
                cellValue=dataBody[currentrow][cols]
                cellValue=cellValue.decode("gbk")
                data=u"%s" %(cellValue)
                self.dataSheet.write_merge(currentrow,rowNum-1,cols,cols,data)
            else:
              for cols in range(3):
                cellValue=dataBody[currentrow][cols]
                cellValue=cellValue.decode("gbk")
                data=u"%s" %(cellValue)
                self.dataSheet.write_merge(currentrow-1,rowNum-1,cols,cols,data)
              for cols in range(6,12):
                cellValue=dataBody[currentrow][cols]
                cellValue=cellValue.decode("gbk")
                data=u"%s" %(cellValue)
                self.dataSheet.write_merge(currentrow-1,rowNum-1,cols,cols,data)
            currentrow=rowNum+1
          break

      for cols in range(3,6):
        cellValue=dataBody[rowNum][cols]
        cellValue=cellValue.decode("gbk")
        data=u"%s" %(cellValue)
        self.dataSheet.write(rowNum,cols,data)

    self.wkbook.save(r'reqq.xlsx')



def test():
  GenTestCase()

if name=="main":
  test()
