maybe because Python is in fashion at the moment?

I still think that the parts that do the heavy lifting are written in some lower level language, but with - how do you call it - python bindings? - so they can easily be deployed in python scripts.

This is definitely something I have seen - I worked on a product where the main code was compiled C#, but the code could learn and write new functions and code stored as Python and executed within.

Yes, the parts that would suffer most from being done in Python are implemented in something faster and called from Python-- Python is the "just do what I want" tool that holds the other stuff together.

When people don't understand why Python is used for machine learning, ask them why anybody would run their GNU/Linux applications from a slow interpreted shell language like Bash. (It doesn't matter, as the Bash interpreter isn't doing the work.) One of the slowest aspects of Python is the way it handles dynamic typing. It's not necessarily a slow implementation of that task, but a task that is notably less efficient than static typing.

I thought that Perl was fully compiled before being executed---if it was only line-by-line interpreted I'd have seen more time between pressing return and seeing syntax errors in some of my bigger Perl scripts. :^) Once that's done, execution speed was only slightly slower than compiled C. There are Perl compilers out there. I don't think I've ever seen any that were OSS but they do (or did) exist). If a compiler doesn't exist for Python, I suspect it won't be long before it does.

Maybe easily dropped in but first you have to find them.

Out of curiosity... does Python have anything like:

• CPAN -- Comprehensive Perl Archive Network
• CRAN -- Comprehensive R Archive Network
• CTAN -- Comprehensive TeX Archive Network

Googling has been helpful in locating some interesting Python modules -- for example, back when I needed to find something to do "fuzzy" pattern matching -- but that doesn't seem as efficient as the Comprehensive Archive Networks and I haven't found anything quite like those for Python. (Just looking to avoid re-inventing the occasional wheel.)

Anyone found something like that yet?

I'm curious as to how you managed to miss it:

https://pypi.org/

https://pypi.org/search/?q=fuzzy+pattern+matching

https://packaging.python.org/tutoria...ling-packages/

I've only dabbled with python, fixing the odd script.
but that was years ago

Plus they have good Python 2 compatibility, considering January is around the corner.

Though I've never done any tasks with Python that benefit from the speed optimisations that PyPi offers. It can't speed up everything.

I think you're mixing up PyPi and PyPy.

Argh! Brain fart, I guess. I went through a marathon session a while back trying to merge several collections of bookmarks, organizing them (shees what a hassle that turned out to be), filling in blanks in some topics (esp. in my "languages" folder) and could have sworn I had saved that one. Again, thanks.

That second link sure would have been better than the way I finally stumbled onto the fuzzy pattern matching module I located ("fuzzywuzzy") for a "crash" effort this past summer. I cannot recall how I wound up locating it though I it may have been via googling and finding the author's project page. (It is listed on PyPI now, though.)
