Question

python怎么读取excel文件

Answer 1

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" % fname nrows = 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_list w.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 xlwt3 if __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。
