python怎么读取excel文件|如何通过Python实现Excel文件读写

1. 怎么用python读取excel表格的数据

一、读excel表读excel要用到xlrd模块，官网安装（http://pypi.python.org/pypi/xlrd）。然后就可以跟着里面的例子稍微试一下就知道怎么用了。大概的流程是这样的：1、导入模块复制代码代码如下:import xlrd2、打开Excel文件读取数据复制代码代码如下:data = xlrd.open_workbook('excel.xls')3、获取一个工作表① table = data.sheets()[0] #通过索引顺序获取② table = data.sheet_by_index(0) #通过索引顺序获取③ table = data.sheet_by_name(u'Sheet1')#通过名称获取4、获取整行和整列的值（返回数组）复制代码代码如下:table.row_values(i)table.col_values(i)5、获取行数和列数复制代码代码如下:table.nrowstable.ncols6、获取单元格复制代码代码如下:table.cell(0,0).valuetable.cell(2,3).value就我自己使用的时候觉得还是获取cell最有用，这就相当于是给了你一个二维数组，余下你就可以想怎么干就怎么干了。得益于这个十分好用的库代码很是简洁。但是还是有若干坑的存在导致话了一定时间探索。现在列出来供后人参考吧：1、首先就是我的统计是根据姓名统计各个表中的信息的，但是调试发现不同的表中各个名字貌似不能够匹配，开始怀疑过编码问题，不过后来发现是因为空格。因为在excel中输入的时候很可能会顺手在一些名字后面加上几个空格或是tab键，这样看起来没什么差别，但是程序处理的时候这就是两个完全不同的串了。我的解决方法是给每个获取的字符串都加上strip（）处理一下。效果良好2、还是字符串的匹配，在判断某个单元格中的字符串（中文）是否等于我所给出的的时候发现无法匹配，并且各种unicode也不太奏效，网络过一些解决方案，但是都比较复杂或是没用。最后我采用了一个比较变通的方式：直接从excel中获取我想要的值再进行比较，效果是不错就是通用行不太好，个呢不能问题还没解决。二、写excel表写excel表要用到xlwt模块，官网下载（http://pypi.python.org/pypi/xlwt）。大致使用流程如下：1、导入模块复制代码代码如下:import xlwt2、创建workbook（其实就是excel，后来保存一下就行）复制代码代码如下:workbook = xlwt.Workbook(encoding = 'ascii')3、创建表复制代码代码如下:worksheet = workbook.add_sheet('My Worksheet')4、往单元格内写入内容复制代码代码如下:worksheet.write(0, 0, label = 'Row 0, Column 0 Value')5、保存复制代码代码如下:workbook.save('Excel_Workbook.xls')由于我的需求比较简单，所以这上面没遇到什么问题，唯一的就是建议还是用ascii编码，不然可能会有一些诡异的现象。当然xlwt功能远远不止这些，他甚至可以设置各种样式之类的。附上一点例子复制代码代码如下:Examples Generating Excel Documents Using Python's xlwtHere are some simple examples using Python's xlwt library to dynamically generate Excel documents.Please note a useful alternative may be ezodf, which allows you to generate ODS (Open Document Spreadsheet) files for LibreOffice / OpenOffice.

2. python中读取excel文件

常用的简单的用法：from xlrd import open_workbookbook=open_workbook(r'C:\Users\admin\Desktop\q.xlsx')sheet=book.sheets_names()[0]#第一个工作表名称sheet=data.sheet_by_name('Sheet1')#获得第一个工作表sheet=book.sheets()[0]#获得第一个工作表#获取总行数nrows = table.nrows#获取总列数ncols = table.ncols#工作表的数目book.nsheetssheet.cell(0,1)sheet.row(0)#读取第二列的内容，从第二行开始，并对其求和sum(x.value for x in sheet.col(1,start_rowx=1))sum(sheet.col_values(1,start_rowx=1))#同上

3. python怎么从excel中读取数据

#导入包

import xlrd

#设置路径

path='C:\Users\jyjh\Desktop\datap.xlsx'

#打开文件

data=xlrd.open_workbook(path)

4. python怎么读写excel文件

最近用python处理一个小项目，其中涉及到对excel的读写操作，通过查资料及实践做了一下总结，以便以后用。

python读写excel文件要用到两个库：xlrd和xlwt，首先下载安装这两个库。

1、#读取Excel

importxlrd

data = xlrd.open_workbook(excelFile)

table = data.sheets()[0]

nrows = table.nrows #行数

ncols = table.ncols #列数

for i in xrange(0,nrows):rowValues= table.row_values(i) #某一行数据for item in rowValues:printitem

2、写Excel文件

'''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'''

defWriteSheetRow(sheet,rowValueList,rowIndex,isBold):

i = 0

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

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

#style2 = xlwt.easyxf('pattern: pattern solid, fore_colour yellow; font: bold on;') # 设置Excel单元格的背景色为黄色，字体为粗体

forsvalue inrowValueList:

strValue = unicode(str(svalue),'utf-8')

ifisBold:

sheet.write(rowIndex,i,strValue,style)

else:

sheet.write(rowIndex,i,strValue)

i = i + 1

'''写excel文件'''

defsave_Excel(strFile):

excelFile = unicode(strFile,"utf8")

wbk = xlwt.Workbook()

sheet = wbk.add_sheet('sheet1',cell_overwrite_ok=True)

headList = ['标题1','标题2','标题3','标题4','总计']

rowIndex = 0

WriteSheetRow(sheet,headList,rowIndex,True)

fori inxrange(1,11):

rowIndex = rowIndex + 1

valueList = []

forj inxrange(1,5):

valueList.append(j*i)

WriteSheetRow(sheet,valueList,rowIndex,False)

wbk.save(excelFile)

style2 = xlwt.easyxf('pattern: pattern solid, fore_colour yellow; font: bold on;')

在设置上Excel单元格的背景色时，fore_colour支持的颜色是有限的，仅支持一下颜色

aqua 0x31black 0x08blue 0x0Cblue_gray 0x36bright_green 0x0Bbrown 0x3Ccoral 0x1Dcyan_ega 0x0Fdark_blue 0x12dark_blue_ega 0x12dark_green 0x3Adark_green_ega 0x11dark_purple 0x1Cdark_red 0x10dark_red_ega 0x10dark_teal 0x38dark_yellow 0x13gold 0x33gray_ega 0x17gray25 0x16gray40 0x37gray50 0x17gray80 0x3Fgreen 0x11ice_blue 0x1Findigo 0x3Eivory 0x1Alavender 0x2Elight_blue 0x30light_green 0x2Alight_orange 0x34light_turquoise 0x29light_yellow 0x2Blime 0x32magenta_ega 0x0Eocean_blue 0x1Eolive_ega 0x13olive_green 0x3Borange 0x35pale_blue 0x2Cperiwinkle 0x18pink 0x0Eplum 0x3Dpurple_ega 0x14red 0x0Arose 0x2Dsea_green 0x39silver_ega 0x16sky_blue 0x28tan 0x2Fteal 0x15teal_ega 0x15turquoise 0x0Fviolet 0x14white 0x09yellow 0x0D"""另外一种方式是 用pyExcelerator

5. python如何读取excel文件

1.首先说明我是使用的python3.5，我的office版本是2010，首先打开dos命令窗，安装必须的两个库，命令是：pip3 install xlrdPip3 install xlwt2.准备好excel，例如我的一个工作文件，我放在D盘/网络经验/11.xlsx，只有一个页签A，内容是一些销售数据3.打开pycharm，新建一个excel.py的文件，首先导入支持库import xlrdimport xlwt4.针对刚入门的新手，先介绍三个知识，第一个:获取excel的sheet名称，第二：获取excel行数与列数，第三：获取第几行第几列的具体值，这是最常用的三个知识点5.贴出代码，具体分析：(1)要操作excel，首先得打开excel，使用open_workbook(‘路径’)(2)要获取行与列，使用nrows(行)，ncols(列)(3)获取具体的值，使用cell(row,col).valueworkbook=xlrd.open_workbook(r'E:11.xlsx')print (workbook.sheet_names()) sheet2=workbook.sheet_by_name('A') nrows=sheet2.nrows ncols=sheet2.ncols print(nrows,ncols) cell_A=sheet2.cell(1,1).value print(cell_A)6.要在excel里写入值，就要使用write属性,重点说明写入是用到xlwt这个支援库，思路是先新建excel，然后新建页签B，然后将一组数据写入到B，最后保存为excel.xls，这里建议保存为2003的格式，大部分电脑都能打开，特别注意保存的excel的路径是在python工作文件的目录下面，贴出代码：stus = [['年', '月'], ['2018', '10'], ['2017', '9'], ['2016', '8']]Excel = xlwt.Workbook() # 新建excelsheet = Excel.add_sheet('B') #新建页签Brow = 0for stu in stus: col = 0 for s in stu: sheet.write(row, col, s) #开始写入 col = col + 1 row = row + 1Excel.save('Excel.xls') #保存关于python如何读取excel文件，青藤小编就和您分享到这里了。如果您对python编程有浓厚的兴趣，希望这篇文章可以为您提供帮助。如果您还想了解更多关于python编程的技巧及素材等内容，可以点击本站的其他文章进行学习。

6. python怎么读取txt 格式excel文件

使用xlwt读取txt文件内容，并且写入到excel中,代码如下，已经加了注释，代码简单，具体代码如下：[python] view plain # coding=utf-8 ''''' main function：主要实现把txt中的每行数据写入到excel中 ''' ################# #第一次执行的代码 import xlwt #写入文件 import xlrd #打开excel文件 fopen=open("e:\\a\\bb\\a.txt",'r') lines=fopen.readlines() #新建一个excel文件 file=xlwt.Workbook(encoding='utf-8',style_compression=0) #新建一个sheet sheet=file.add_sheet('data') ############################ #写入写入a.txt，a.txt文件有20000行文件 i=0 for line in lines: sheet.write(i,0,line) i=i+1 ################################# #第二层执行代码，写入b.txt， j=20001 #从20001行写入 fopen2=open("e:\\a\\bb\\b.txt",'r') lines2=fopen2.readlines() for line in lines2: sheet.write(j,0,line) j=j+1 file.save('minni.xls')

7. 如何通过Python实现Excel文件读写

参考代码如下：# -*- coding: utf-8 -*- import xdrlib ,sysimport xlrddef open_excel(file= 'file.xls'):try:data = xlrd.open_workbook(file)return dataexcept Exception,e:print str(e)#根据索引获取Excel表格中的数据 参数:file：Excel文件路径 colnameindex：表头列名所在行的所以 ，by_index：表的索引def excel_table_byindex(file= 'file.xls',colnameindex=0,by_index=0):data = open_excel(file)table = data.sheets()[by_index]nrows = table.nrows #行数ncols = table.ncols #列数colnames = table.row_values(colnameindex) #某一行数据 list =[]for rownum in range(1,nrows):row = table.row_values(rownum)if row:app = {}for i in range(len(colnames)):app[colnames[i]] = row[i] list.append(app)return list#根据名称获取Excel表格中的数据 参数:file：Excel文件路径 colnameindex：表头列名所在行的所以 ，by_name：Sheet1名称def excel_table_byname(file= 'file.xls',colnameindex=0,by_name=u'Sheet1'):data = open_excel(file)table = data.sheet_by_name(by_name)nrows = table.nrows #行数 colnames = table.row_values(colnameindex) #某一行数据 list =[]for rownum in range(1,nrows):row = table.row_values(rownum)if row:app = {}for i in range(len(colnames)):app[colnames[i]] = row[i]list.append(app)return listdef main():tables = excel_table_byindex()for row in tables:print rowtables = excel_table_byname()for row in tables:print rowif __name__=="__main__":main()

8. python 如何读取 excel 指定单元格内容

1、首先打开电脑上编写python的软件。

9. python怎么读取excel文件

1.读取Excel(需要安装xlrd)：

#-*- coding: utf8 -*-import xlrdfname = "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_valuerow_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_valuerow_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 shutilfname = "./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_valuerow_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/"+filenameprint "%s %s %s" %(i,row_data[3],filepath)if os.path.exists(filepath):shutil.(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。
