Hello,
Thanks for the answer.
I quite get the drift of your explanations. But my question was looking for
a specific practical answer.
As my codes involve a lot of mathematical formulae and some of them require
ultra-high precision, hence I was looking for an answer that either Fortran
Hi Michael,
Your question appears to be specifically about the ArcGIS library.
Unfortunately, I would assume very few of us have expertise on this
particular third-party mapping library; we're mostly a forum for
teaching basic Python programming. We can help on non-domain-specific

I want to assemble a script to: 1) input a folder with shapefiles with
different coordinate systems, 2) allow the user through a toolbox script to
choose a desired coordinate system, and then 3) export all the shapefiles
with the new coordinate system to a new folder.
So the problem is I don't kno

These days, most important scientific libraries are wrapped so that you
call call them directly from python. Google for "python bindings " and see if you get any hits. If you have a library
that doesn't have python bindings, you can probably make them. Start

True, because the vast majorioty of "scientific codes" (ie libraries)
were written many years ago and are still maintained in the languages

Scientists do not like to code in Fortran. Anybody who tells you that is
mistaken. If they
Hi,
Thanks for replying!
I understand as you said that since it was the very first language available
to them therefore scientists at large got stuck with it as I presume it
would have become the primary programming language example given in their
textbooks or study materials.
However your reply
Greetings Steven,
Much great advice snipped.
Is it possible (using U+1F600 through U+1F64F or otherwise) to offer
a standing ovation for such a relevant, thorough, competent and
well-written reply?
Thank you, as always,

Hello
I've been using Python 27 on Windows for as long as I have used a computer
for intelligent purposes, viz. since 2000 I think, well the earlier versions
till the current version I'm using now. I used it primarily for mathematical
precision on numerical computations. I make my own codes.
