xlrd VS GNU Emacs

Extraction: https://www.python-excel.org/

xlwt ([OPTION] For export xls files)

Have a look at some of the projects linked on this page.

Yes you’ll be able to automate. Try this website that lists a few Python Excel libraries. https://www.python-excel.org/

As business requirements evolve, certain features are expected to evolve as well. That was the case for me few days ago when I had to implement a feature where Django model's data are converted to .xlsx excel format and sent, as attachment, to a provided email address literally. It was a big problem for me to figure out how to do this with that file extension as most available solutions were using the old .xls excel file extension and none really talked about sending excel file as attachments of an email sent via Django. To solve this problem, I looked at a similar solution by Vitor Freitas who used xlwt to export Django model's data to .xls excel file format and served it as response data to the user for download. Though a great companion, I needed a different file extension and was solving a slightly different problem. From further research, I came across Working with Excel Files in Python, from Working with Spreadsheets using Python, which recommended openpyxl for "reading and writing Excel 2010 files (ie: .xlsx)" so I decided to try the package out. This experience birthed this article where I utilized coingecko's api to periodically fetch cryptocurrency's coin's data, store the data in a database, and then display as well as allow users to extract the data to excel files sent to any email address provided. It's my deepest hope that you will find it helpful.

Great. What library are you using? (There's a half dozen of them.) Are you reading in an Excel file directly or exporting/importing through csv's? df2 and inplace sound like pandas dataframes -- are you using that?

Use http://www.python-excel.org/ and consider this process:

gnu.org - contains everything you need to research his philosophy.

stallman.org - personal website, contains a lot of opinion, but I absolutely respect this man in all what he says.

emacs.org (redirects to https://www.gnu.org/software/emacs/) - his non-philosophical work, one of two mainstream console text editors.

Forever, there was a file included in stock Emacs, `spook.el`, which could be hooked up to automatically add random strings of "interesting" keywords to each of your email or Usenet messages (in signatures, or in headers like `X-Spook`).

Looks like copyright date of 1988:

Try `M-x spook RET` in an Emacs buffer.

If you want to spare a couple of detours, you probably could start with Emacs Org-mode according to Greenspun's eleventh rule: "Any sufficiently complicated PIM or note-taking program contains an ad hoc, informally specified, bug-ridden, slow implementation of half of Org mode."

Emacs: winget install GNU.Emacs

The whole cl-lib thing is a total disaster:

https://github.com/emacs-mirror/emacs/blob/master/lisp/emacs...

They added cl- as a prefix to each Common Lisp symbol.

FIRST is now called cl-first, CAAAR is now cl-caaar .

I would really prefer if GNU Emacs removes all Common Lisp functionality, instead of creating this really wacky stuff, with discussions about this topic every year.

Never too late to try! Take your time. Emacs will outlive us all. https://www.gnu.org/software/emacs/

GNU Emacs is a versatile, open-source text editor that offers extensibility and customization—a sort of self-documenting real-time display editor. Our thanks for the suggestion go to CartanAnnullator.

Emacs

Their DEFUN and DEFVAR macros for example let us define a function or a variable that will be available as a Lisp function, and can be used as an ordinary C function from the C code. Emacs is written in pure C99 language and works with both GCC and Clang I believe. We can just define a C function via macro, and it is auto exported and made available to Lisp. For example my first patch to Emacs was for this function (we added "count" argument to make it possible to skip enumerating files in a directory for the case when user code is just interesting if a directory is empty or not):
