python读取表格数据

A. python中的pandas如何读取excel中指定单元格的值

pandas 读取指定单元格 第2行，第3列
import pandas as pd
df = pd.read_excel('测试.xlsx')
cell = df.iat[0, 2]
[0, 2] 表示单元格的行列 pandas 默认跳过表头从第二行开始 第三列是2 (012)

Python读写EXCEL文件常用方法大全

1 前言
python读写excel的方式有很多，不同的模块在读写的讲法上稍有区别，这里我主要介绍几个常用的方式。

用xlrd和xlwt进行excel读写；

用openpyxl进行excel读写；

用pandas进行excel读写；
参考：
https://www.python-excel.org/
https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_excel.html#pandas.read_excel

2 数据准备

为了方便演示，我这里新建了一个data.xls和data.xlsx文件，第一个工作表sheet1区域“A1:E5”的内容如下，用于测试读写excel的代码：


3 xlrd和xlwt

xlrd是一个库，用于从Excel文件中以.xls格式读取数据和格式化信息
xlwt是一个库，用于将数据和格式化信息写入较旧的Excel文件(例如:.xls)。

示例

pip install xlrd
pip install xlwt


我们开始来读取文件的内容

import xlrd
import os

file_path = os.path.dirname(os.path.abspath(__file__))
base_path = os.path.join(file_path, 'data.xlsx')
book = xlrd.open_workbook(base_path)
sheet1 = book.sheets()[0]
nrows = sheet1.nrows
print('表格总行数', nrows)
ncols = sheet1.ncols
print('表格总列数', ncols)
row3_values = sheet1.row_values(2)
print('第3行值', row3_values)
col3_values = sheet1.col_values(2)
print('第3列值', col3_values)
cell_3_3

C. 使用python读取excel中的数据，并重新写入到新的excel中

使用Python3运行
起初是读取excel中的数据，进行相关的计算将结果追加在后面，没有找到合适的办法，就只能采用这种读取数据，进行相关操作，重新写入的方法

(1)使用xlrd打开xls文件，读取数据
(2)将需要的数据放进list中，进行相应的计算得出结果
(3)使用xlutils的将xlrd对象转化为xlwt对象
(4)使用转化的xlwt对象的write方法，将结果写入
(5)使用xlwt的save进行保存

主要用它读取Excel数据

主要用它来将数据写入到excel中

主要用xlutils的方法将xlrd对象转化为xlwt对象，好来进行写入

删除了一些东西大致如下

D. python怎么读取excel的数据

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 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）

12345678from 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：

252627282930313233#-*-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。

2526import 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

E. 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 xlrd
2、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.nrows
table.ncols

6、获取单元格

复制代码代码如下:
table.cell(0,0).value
table.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 xlwt

2、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:
