Python xlwt - accessing existing cell content, auto-adjust column width

早过忘川 提交于 2019-11-27 00:57:47
I am trying to create an Excel workbook where I can auto-set, or auto-adjust the widths of the columns before saving the workbook. I have been reading the Python-Excel tutorial in hopes of finding some functions in xlwt that emulate xlrd ones (such as sheet_names() , cellname(row, col) , cell_type , cell_value , and so on...) For example, suppose I have the following: from xlwt import Workbook wb = Workbook() sh1 = wb.add_sheet('sheet1' , cell_overwrite_ok = True) sh2 = wb.get_sheet(0) wb.get_sheet(0) is similar to the rb.sheet_by_index(0) function offered in xlrd, except that the former

In the documentation for xlrd and xlwt I have learned the following: How to read from existing work-books/sheets: from xlrd import open_workbook wb = open_workbook("ex.xls") s = wb.sheet_by_index(0) print s.cell(0,0).value #Prints contents of cell at location a1 in the first sheet in the document called ex.xls How to create new work-books/sheets: from xlwt import Workbook wb = Workbook() Sheet1 = wb.add_sheet('Sheet1') Sheet1.write(0,0,'Hello') wb.save('ex.xls') #Creates a document called ex.xls with a worksheet called "Sheet1" and writes "Hello" to the cell located at a1 What I want to do now

python简单应用!用爬虫来采集天猫所有优惠券信息,写入本地文件

今天给大家分享一个小网站的数据采集,并写到excel里面! 分析网站 目标网站是“小咪购”,这里有天猫所有的含有购物券的商品信息,我们今天就来抓它吧! 随便找一段文字,然后点击右键查看网页源代码,看看是否存在该文字,如果存在,那么这个网页就是静态网站了!很幸运,这个网站居然是静态的。 那就简单了,不需要去分析ajax加载数据或者找json包了,直接获取网页源代码==>>匹配相关内容==>>保存数据即可! 工具和库 Windows+python3.6 import random import time import requests from lxml import etree import xlwt 用这几个库就可以搞定了!注意xlwt和xlrd这2个库都是操作excel的,一个是保存数据,一个是读取数据,不要搞混了。 开始写代码 首先写一个函数,将所有的爬虫工作写到函数里,如下图 这个网站需要写上headers,不写是抓不到数据的!新建一个列表,将爬到的相关数据写入列表,它的形式大概是这样的:【【产品信息A1,2,3……】,【产品信息B1,2,3……】……】,这么写列表是因为我们最后要将他们写如excel表格,那么列表中的每一个元素(还是列表形式)都是一行数据,方便写入! 注意第33行,列表构成的时候,用+连接会将所有列表中的元素放入一个列表,比如:【1,2,3】+【4,5】=

问题 On a django site, I want to generate an excel file based on some data in the database. I'm thinking of using xlwt, but it only has a method to save the data to a file. How can get the file to the HttpResponse object? Or maybe do you know a better library? I've also found this snippet but it doesn't do what I need. All I want is a way to get the stream from the xlwt object to the response object (without writing to a temporary file) 回答1: neat package! i didn't know about this According to the
