python操作excel表格

A. python怎麼從excel中讀取數據

• #導入包

  import xlrd

  #設置路徑

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

  #打開文件

  data=xlrd.open_workbook(path)

  

B. 如何用python操作excel

指定選取三列然後挑選出同時滿足>=1或者同時<=-1的 將其所有數據存入新的csv表格中
程序如下：

D. 怎樣用python，讀取excel中的一列數據

用python讀取excel中的一列數據步驟如下：

1、首先打開dos命令窗，安裝必須的兩個庫，命令是：pip3 installxlrd；Pip3 install xlwt。

E. Python可以處理excel表格嗎

可以，python有xlrd、xlwt、xlwings、xlutils、pandas等庫可用於處理excel表格，pip install這些庫就可以使用。

F. 怎麼用python讀取excel表格的數據

一、讀excel表
讀excel要用到xlrd模塊，官網安裝（http://pypi.python.org/pypi/xlrd）。然後就可以跟著裡面的例子稍微試一下就知道怎麼用了。大概的流程是這樣的：
1、導入模塊

復制代碼代碼如下:
import xlrd
2、打開Excel文件讀取數據

復制代碼代碼如下:
data = xlrd.open_workbook('excel.xls')
3、獲取一個工作表
① table = data.sheets()[0] #通過索引順序獲取
② table = data.sheet_by_index(0) #通過索引順序獲取
③ table = data.sheet_by_name(u'Sheet1')#通過名稱獲取
4、獲取整行和整列的值（返回數組）

復制代碼代碼如下:
table.row_values(i)
table.col_values(i)

5、獲取行數和列數

復制代碼代碼如下:
table.nrows
table.ncols

6、獲取單元格

復制代碼代碼如下:
table.cell(0,0).value
table.cell(2,3).value

就我自己使用的時候覺得還是獲取cell最有用，這就相當於是給了你一個二維數組，餘下你就可以想怎麼干就怎麼幹了。得益於這個十分好用的庫代碼很是簡潔。但是還是有若干坑的存在導致話了一定時間探索。現在列出來供後人參考吧：
1、首先就是我的統計是根據姓名統計各個表中的信息的，但是調試發現不同的表中各個名字貌似不能夠匹配，開始懷疑過編碼問題，不過後來發現是因為空格。因為在excel中輸入的時候很可能會順手在一些名字後面加上幾個空格或是tab鍵，這樣看起來沒什麼差別，但是程序處理的時候這就是兩個完全不同的串了。我的解決方法是給每個獲取的字元串都加上strip（）處理一下。效果良好
2、還是字元串的匹配，在判斷某個單元格中的字元串（中文）是否等於我所給出的的時候發現無法匹配，並且各種unicode也不太奏效，網路過一些解決方案，但是都比較復雜或是沒用。最後我採用了一個比較變通的方式：直接從excel中獲取我想要的值再進行比較，效果是不錯就是通用行不太好，個呢不能問題還沒解決。
二、寫excel表
寫excel表要用到xlwt模塊，官網下載（http://pypi.python.org/pypi/xlwt）。大致使用流程如下：
1、導入模塊

復制代碼代碼如下:
import xlwt

2、創建workbook（其實就是excel，後來保存一下就行）

復制代碼代碼如下:
workbook = xlwt.Workbook(encoding = 'ascii')

3、創建表

復制代碼代碼如下:
worksheet = workbook.add_sheet('My Worksheet')

4、往單元格內寫入內容

復制代碼代碼如下:
worksheet.write(0, 0, label = 'Row 0, Column 0 Value')

5、保存

復制代碼代碼如下:
workbook.save('Excel_Workbook.xls')

由於我的需求比較簡單，所以這上面沒遇到什麼問題，唯一的就是建議還是用ascii編碼，不然可能會有一些詭異的現象。
當然xlwt功能遠遠不止這些，他甚至可以設置各種樣式之類的。附上一點例子

復制代碼代碼如下:

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.name = ?
font.outline = ?
font.shadow = ?
Setting the Width of a Cell
import xltw
workbook = xlwt.Workbook()

workbook.save('Excel_Workbook.xls')
Entering a Date into a Cell
import xlwt
import datetime
workbook = xlwt.Workbook()

G. 用python對excel操作，將配方羅列出來

如我下圖所示，D2單元格輸入公式=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。（公式中的單元格引用可根據你表格實際進行修改套用）

H. 如何用python處理excel數據

想要更好的處理這項數據，那麼你必須得用一些統計的表格來進行歸納。

I. Python能讀寫Excel表格嗎

Python有非常多的excel相關模塊，插入圖表、公式、單元格合並...，基本可以不安裝excel了。

J. python操作excel的問題。如何找到某一列的第一個空白單元格

循環遍歷每一行，再遍歷每一列，判斷是否為空。推薦tablib這個庫。操作excel十分簡單。
