作者 | 黄伟呢 出品 | 数据分析与统计学之美（ID:gh_21c25c7e71d0） 头图 | CSDN 下载自视觉中国 背景 Vlookup 函数 ，可以算是一个数据专员必须要会使用的基本函数了，确实很好用。但是你可能会注意到，Excel 一旦数据量过大，打开都费劲了，何况打开后，你还要输入公式计算，就更费劲了，此时你有没有想到过 被称作“万金油”的 Python ，他好像啥都可以做，是不是很牛逼？对于Excel来说的大数据量，但是对于 Python 来说，应该是小菜一碟。 今天我就带着大家对比学习一下，怎么分别在 Excel 和 Python 中使用 Vlookup 函数。 数据源介绍 如图所示，有一个“ vlookup.xlsx ”文件，“ A1:F11 ”是我们的数据源区域，“ K1:L5 ”是我们的查找源区域。我们的目的就是要在数据源区域的 G 列加一列数据，查找出不同类型下名称表示。 Vlookup函数介绍 这个函数我想大家应该都会，大家应该也不需要我介绍的太详细，因此我就简单的为大家介绍一下 vlookup 函数的语法。 参数说明：vlookup (待查找目标, 查找区域, 匹配值所在的列, 精确匹配 OR 模糊查找)； 用一句通俗的话来说明 vlookup 函数的用法：针对每一个待查找目标，它就能从指定的查找区域中，查找返回想要查找到的值。

哈喽大家好，我是鹏哥。 今天要记录的学习主题是 —— Excel表处理神器： openpyxl库 ~~~上课铃~~~ 1 写在前面 之前我想过 要不要写一篇关于如何处理excle表的博客，可是网上一搜都是有太多的文章了。python处理excel表的库，常见的有：xlrd、xlwt、xlwings、openpyxl、win32com、pandas等。 针对python各类第三方库，支持情况如下： 介于网上有这么多精彩的博客，我就一直懒的再去做总结。不过昨天小杰找到我，让我帮他处理下excel表数据。我说你自己百度下不就行了吗？他说网 上的看不懂。 （虽然我觉得他肯定是没认真看 ） 好吧，既然如此，我就为你写篇博客，让你能快速掌握excel表吧！ 2 openpyxl库 这里我主要介绍openpyxl库的几类常见方法。至于为什么是openpyxl，主要是我自己平时习惯用openpyxl，其他库已经不熟悉了。 1、打开/创建excel文件 from openpyxl import * # 打开已有test.xlsx表 wb1 = load_workbook('test.xlsx') # 创建xlsx表,结束后以test.xlsx表保存 wb2 = Workbook() ws = wb2.active wb2.save('test.xlsx') 2、选择/创建sheet表 、 #

Using PIP to install openpyxl for a user

问题 I've written a script that will enable a user to have their weekly timesheet's filled out automatically and save it as a new excel spreadsheet. I thought I would be able to just have the Openpyxl folder in the same directory as the script for it to import but it does not seem to work. I have put together a bit of code based off a few other threads below to check for openpyxl before it imports. So I can hopefully have the ability to setup openpyxl. I intend to have this bit of code run during

问题 I'm trying to insert into a MySQL table from data in this Excel sheet: https://www.dropbox.com/s/w7m282386t08xk3/GA.xlsx?dl=0 The script should start from the second sheet "Daily Metrics" at row 16. The MySQL table already has the fields called date, campaign, users, and sessions. Using Python 2.7, I've already created the MySQL connection and opened the sheet, but I'm not sure how to loop over those rows and insert into the database. import MySQLdb as db from openpyxl import load_workbook wb

Insert an image into Excel with openpyxl

问题 My PC crashed and so I had to reinstall all of my libraries; after finishing the install, I realized that some libraries updated to a new version and my code no longer works (due to a new version of openpyxl). I am trying to insert an image into an Excel file, but I do not understand the error messages that are occurring. Other questions seem to be for older versions of openpyxl (for which my original code worked), but do not work for the current version of openpyxl. Your assistance in

why pandas dataframe style lost when saved with “to_excel”?

由 懵懂的女人 提交于 2021-02-07 13:51:53
问题 Per this example the to_excel method should save the Excel file with background color. However, my saved Excel file does not have any color in it. I tried to write using both openpyxl and xlsxwriter engines. In both cases, the Excel file was saved, but the cell color/style was lost. I can read the file back and reformat with openpyxl , but if this to_excel method is supposed to work, why doesn't it? Here is the sample code. import pandas as pd # version 0.24.2 dict = {'A': [1, 1, 1, 1, 1], 'B

Insert an image from url in openpyxl

问题 I would like to insert an image from URL into the xlsx file. How could I do that with openpyxl? I checked the documentation but not shows how to insert an image from URL. 回答1: There is no built-in function in Openpyxl to insert images through URLs. You'll need to use an Http client module for python.(example: urllib ) import openpyxl from openpyxl.writer.excel import save_virtual_workbook from openpyxl.drawing.image import Image import PIL import io import urllib3 wb = openpyxl.Workbook() ws

How can I use an external python library in AWS Glue?

问题 First stack overflow question here. Hope I do this correctly: I need to use an external python library in AWS glue. "Openpyxl" is the name of the library. I follow these directions: https://docs.aws.amazon.com/glue/latest/dg/aws-glue-programming-python-libraries.html However, after I have my zip file saved in the correct s3 location and point my glue job to that location, I'm not sure what to actually write in the script. I tried your typical Import openpyxl , but that just returns the
