Python读写Excel文件的实例

最近由于经常要用到Excel,需要根据Excel表格中的内容对一些apk进行处理,手动处理很麻烦,于是决定写脚本来处理。首先贴出网上找来的读写Excel的脚本。
1.读取Excel(需要安装xlrd):

#-*- coding: utf8 -*-import xlrd fname = "reflect.xls"bk = xlrd.open_workbook(fname)shxrange = range(bk.nsheets)try: sh = bk.sheet_by_name("Sheet1")except: print "no sheet in %s named Sheet1" % fname#获取行数nrows = sh.nrows#获取列数ncols = sh.ncolsprint "nrows %d, ncols %d" % (nrows,ncols)#获取第一行第一列数据 cell_value = sh.cell_value(1,1)#print cell_value row_list = []#获取各行数据for i in range(1,nrows): row_data = sh.row_values(i) row_list.append(row_data)

2.写入Excel(需安装pyExcelerator)

from pyExcelerator import *w = Workbook()  #创建一个工作簿ws = w.add_sheet('Hey, Hades')  #创建一个工作表ws.write(0,0,'bit') #在1行1列写入bitws.write(0,1,'huang') #在1行2列写入huangws.write(1,0,'xuan') #在2行1列写入xuanw.save('mini.xls')  #保存

3.再举个自己写的读写Excel的例子
读取reflect.xls中的某些信息进行处理后写入mini.xls文件中。 

#-*- coding: utf8 -*-import xlrdfrom pyExcelerator import *  w = Workbook() ws = w.add_sheet('Sheet1') fname = "reflect.xls"bk = xlrd.open_workbook(fname)shxrange = range(bk.nsheets)try: sh = bk.sheet_by_name("Sheet1")except: print "no sheet in %s named Sheet1" % fnamenrows = sh.nrowsncols = sh.ncolsprint "nrows %d, ncols %d" % (nrows,ncols) cell_value = sh.cell_value(1,1)#print cell_value row_list = []mydata = []for i in range(1,nrows): row_data = sh.row_values(i) pkgdatas = row_data[3].split(',') #pkgdatas.split(',') #获取每个包的前两个字段 for pkgdata in pkgdatas:  pkgdata = '.'.join((pkgdata.split('.'))[:2])  mydata.append(pkgdata) #将列表排序 mydata = list(set(mydata)) print mydata #将列表转化为字符串 mydata = ','.join(mydata) #写入数据到每行的第一列 ws.write(i,0,mydata) mydata = [] row_list.append(row_data[3])#print row_listw.save('mini.xls')

4.现在我需要根据Excel文件中满足特定要求的apk的md5值来从服务器获取相应的apk样本,就需要这样做: 

#-*-coding:utf8-*-import xlrdimport osimport shutil fname = "./excelname.xls"bk = xlrd.open_workbook(fname)shxrange = range(bk.nsheets)try: #打开Sheet1工作表 sh = bk.sheet_by_name("Sheet1")except: print "no sheet in %s named Sheet1" % fname#获取行数nrows = sh.nrows#获取列数ncols = sh.ncols#print "nrows %d, ncols %d" % (nrows,ncols)#获取第一行第一列数据cell_value = sh.cell_value(1,1)#print cell_value row_list = []#range(起始行,结束行)for i in range(1,nrows): row_data = sh.row_values(i) if row_data[6] == "HXB":  filename = row_data[3]+".apk"  #print "%s %s %s" %(i,row_data[3],filename)  filepath = r"./1/"+filename  print "%s %s %s" %(i,row_data[3],filepath)  if os.path.exists(filepath):   shutil.copy(filepath, r"./myapk/")

补充一个使用xlwt3进行Excel文件的写操作。

import xlwt3if __name__ == '__main__':datas = [['a', 'b', 'c'], ['d', 'e', 'f'], ['g', 'h']]#二维数组file_path = 'D:\\test.xlsx'wb = xlwt3.Workbook()sheet = wb.add_sheet('test')#sheet的名称为test#单元格的格式style = 'pattern: pattern solid, fore_colour yellow; '#背景颜色为黄色style += 'font: bold on; '#粗体字style += 'align: horz centre, vert center; '#居中header_style = xlwt3.easyxf(style)row_count = len(datas)col_count = len(datas[0])for row in range(0, row_count): col_count = len(datas[row]) for col in range(0, col_count):if row == 0:#设置表头单元格的格式sheet.write(row, col, datas[row][col], header_style)else:sheet.write(row, col, datas[row][col])wb.save(file_path)

输出的文件内容如下图:

注:以上代码在Python 3.x版本测试通过。

好了,python操作Excel就这么!些了,简单吧
