问题 can you teach me whether Python can write into a same Excel file, but 2 different spreadsheets (tabs)? Just for example, I want to pick and write the titles of below 4 websites, and write them into the same file title.xls but respectively in its Sheet1 and Sheet 2. www.dailynews.com www.dailynews.co.zw www.gulf-daily-news.com www.dailynews.gov.bw I do them in 2 scripts, each for 2 websites: from bs4 import BeautifulSoup import urllib2 import xlwt line_in_list = ['www.dailynews.com','www

问题 The Problem Creation of fancy reports using Pandas and Python. Proposed Solution Using a template xlsx file containing a template sheet nicely formatted with references to another pre-populated worksheet, delete the pre-populated sheet and insert the new worksheet from pandas. The template sheet will lose the links reverting to #REF so these will need to be renamed. I tried: import os import xlrd, xlwt import envconfig swb1 = xlrd.open_workbook(os.path.join(envconfig.REPORT_WRITER_PATH,

问题 I am trying to read a list of values in a column in an excel sheet. However, the length of the column varies every time, so I don't know the length of the list. How do I get python to read all the values in a column and stop when the cells are empty using xlrd? 回答1: for i in range(worksheet.nrows): will iterate through all the rows in the worksheet if you were interested in column 0 for example c0 = [worksheet.row_values(i)[0] for i in range(worksheet.nrows) if worksheet.row_values(i)[0]] or

xlwt - How to add page breaks to an Excel File?

由 天涯浪子 提交于 2019-12-07 10:07:42
问题 I'm trying to add page breaks whenever a column's value changes in Excel using Python and xlwt. Does anyone know how to do this? I found one example but they don't really say if their code works, and they don't say what the numbers mean in the tuple: ws.horz_page_breaks = [(54, 0, 255), (108, 0, 255)] 回答1: Doing some web research I found this OpenOffice.org document describing Excel's format and BIFF records. It seems for horizontal breaks (pag. 181), each tuple represents: Index to first row

Python Excel template read and re-write, maintaining formulae and formatting

由 末鹿安然 提交于 2019-12-07 04:29:28
问题 I've run the gamut and can't seem to find what I'm looking for. All threads I found here end up in dead ends for me. xlrd, xlwt, and xlutils almost do what I need, but… The basic idea is that I need to use Python to write simple data (strings) to a particular sheet of an Excel template and write out that template to a new .xls file. Reading in the template, copying it to a new workbook object, writing in the new values, and writing out the new .xls file is no problem. However, I cannot find a
