python操作excel表格

A. 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)

  

B. 如何用python操作excel

指定选取三列然后挑选出同时满足>=1或者同时<=-1的 将其所有数据存入新的csv表格中
程序如下：

C. python操作excel问题

# -*- coding: utf-8 -*-#导入xlwt模块import xlwt# 创建一个Workbook对象，这就相当于创建了一个Excel文件book = xlwt.Workbook(encoding='utf-8', style_compression=0)'''Workbook类初始化时有encoding和style_compression参数encoding:设置字符编码，一般要这样设置：w = Workbook(encoding='utf-8')，就可以在excel中输出中文了。默认是ascii。当然要记得在文件头部添加：#!/usr/bin/env python# -*- coding: utf-8 -*-style_compression:表示是否压缩，不常用。'''#创建一个sheet对象，一个sheet对象对应Excel文件中的一张表格。# 在电脑桌面右键新建一个Excel文件，其中就包含sheet1，sheet2，sheet3三张表sheet = book.add_sheet('test', cell_overwrite_ok=True)# 其中的test是这张表的名字,cell_overwrite_ok，表示是否可以覆盖单元格，其实是Worksheet实例化的一个参数，默认值是False# 向表test中添加数据sheet.write(0, 0, 'EnglishName') # 其中的'0-行, 0-列'指定表中的单元，'EnglishName'是向该单元写入的内容sheet.write(1, 0, 'Marcovaldo')txt1 = '中文名字'sheet.write(0, 1, txt1.decode('utf-8')) # 此处需要将中文字符串解码成unicode码，否则会报错txt2 = '马可瓦多'sheet.write(1, 1, txt2.decode('utf-8')) # 最后，将以上操作保存到指定的Excel文件中book.save(r'e:\test1.xls') # 在字符串前加r，声明为raw字符串，这样就不会处理其中的转义了。否则，可能会报错

D. 怎样用python，读取excel中的一列数据

用python读取excel中的一列数据步骤如下：

1、首先打开dos命令窗，安装必须的两个库，命令是：pip3 installxlrd；Pip3 install xlwt。

E. Python可以处理excel表格吗

可以，python有xlrd、xlwt、xlwings、xlutils、pandas等库可用于处理excel表格，pip install这些库就可以使用。

F. 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:

Examples Generating Excel Documents Using Python's xlwt
Here 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. You can check them out at:http://packages.python.org/ezodf/index.html
The Simplest Example
import xlwt
workbook = xlwt.Workbook(encoding = 'ascii')
worksheet = workbook.add_sheet('My Worksheet')
worksheet.write(0, 0, label = 'Row 0, Column 0 Value')
workbook.save('Excel_Workbook.xls')
Formatting the Contents of a Cell
import xlwt
workbook = xlwt.Workbook(encoding = 'ascii')
worksheet = workbook.add_sheet('My Worksheet')
font = xlwt.Font() # Create the Font
font.name = 'Times New Roman'
font.bold = True
font.underline = True
font.italic = True
style = xlwt.XFStyle() # Create the Style
style.font = font # Apply the Font to the Style
worksheet.write(0, 0, label = 'Unformatted value')
worksheet.write(1, 0, label = 'Formatted value', style) # Apply the Style to the Cell
workbook.save('Excel_Workbook.xls')
Attributes of the Font Object
font.bold = True # May be: True, False
font.italic = True # May be: True, False
font.struck_out = True # May be: True, False
font.underline = xlwt.Font.UNDERLINE_SINGLE # May be: UNDERLINE_NONE, UNDERLINE_SINGLE, UNDERLINE_SINGLE_ACC, UNDERLINE_DOUBLE, UNDERLINE_DOUBLE_ACC
font.escapement = xlwt.Font.ESCAPEMENT_SUPERSCRIPT # May be: ESCAPEMENT_NONE, ESCAPEMENT_SUPERSCRIPT, ESCAPEMENT_SUBSCRIPT
font.family = xlwt.Font.FAMILY_ROMAN # May be: FAMILY_NONE, FAMILY_ROMAN, FAMILY_SWISS, FAMILY_MODERN, FAMILY_SCRIPT, FAMILY_DECORATIVE
font.charset = xlwt.Font.CHARSET_ANSI_LATIN # May be: CHARSET_ANSI_LATIN, CHARSET_SYS_DEFAULT, CHARSET_SYMBOL, CHARSET_APPLE_ROMAN, CHARSET_ANSI_JAP_SHIFT_JIS, CHARSET_ANSI_KOR_HANGUL, CHARSET_ANSI_KOR_JOHAB, CHARSET_ANSI_CHINESE_GBK, CHARSET_ANSI_CHINESE_BIG5, CHARSET_ANSI_GREEK, CHARSET_ANSI_TURKISH, CHARSET_ANSI_VIETNAMESE, CHARSET_ANSI_HEBREW, CHARSET_ANSI_ARABIC, CHARSET_ANSI_BALTIC, CHARSET_ANSI_CYRILLIC, CHARSET_ANSI_THAI, CHARSET_ANSI_LATIN_II, CHARSET_OEM_LATIN_I
font.colour_index = ?
font.get_biff_record = ?
font.height = 0x00C8 # C8 in Hex (in decimal) = 10 points in height.
font.name = ?
font.outline = ?
font.shadow = ?
Setting the Width of a Cell
import xltw
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('My Sheet')
worksheet.write(0, 0, 'My Cell Contents')
worksheet.col(0).width = 3333 # 3333 = 1" (one inch).
workbook.save('Excel_Workbook.xls')
Entering a Date into a Cell
import xlwt
import datetime
workbook = xlwt.Workbook()

G. 用python对excel操作，将配方罗列出来

如我下图所示，D2单元格输入公式=IFERROR(TEXT(LOOKUP(9^9,--RIGHT(MID($A1,1,FIND(D$1,$A1)-1),ROW($1:$9))),"0.00%"),"")

右拉再下拉公式即可。（公式中的单元格引用可根据你表格实际进行修改套用）

H. 如何用python处理excel数据

想要更好的处理这项数据，那么你必须得用一些统计的表格来进行归纳。

I. Python能读写Excel表格吗

Python有非常多的excel相关模块，插入图表、公式、单元格合并...，基本可以不安装excel了。

J. python操作excel的问题。如何找到某一列的第一个空白单元格

循环遍历每一行，再遍历每一列，判断是否为空。推荐tablib这个库。操作excel十分简单。
