[issue41592] Make _SubParsersAction public
Eric Pederson added the comment: Yes - that was the first thing I tried and why I logged the bug. I will log a bug with Pycharm but it still seems like the long term solution is to make _SubParsersAction public since it is used like a public object. I thought that logging the bug here would be the start of the discussion by the argparse maintainers. Where can I get their attention? -- ___ Python tracker <https://bugs.python.org/issue41592> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue41592] Make _SubParsersAction public
New submission from Eric Pederson :
ArgumentParser.add_subparsers() returns a _SubParsersAction. This requires
user code using type annotations to use a protected type which causes type
checkers like PyCharm to complain. For example:
def add_subparser(name: str, subparser: _SubParsersAction, subparsers: dict) ->
ArgumentParser:
parser = subparser.add_parser(name)
parser.add_argument('-v', '--verbose', action='store_true')
subparsers[name] = parser
return parser
You can't use plain Action because Action doesn't have the add_parser() method.

To my mind, the more sensible job you do at programming this the worse
off you are, unless you use strong encryption. There are nearly
infinite approaches, so the random approach you use will be part of the
security of the obfuscation.
OK, I am not really taking this so seriously, but it is a fun question
(Python makes these minor things fun). Is there anyway to do this in
Python? You bet, so many ways... here's another:

Re: Why does Python never add itself to the Windows path?
Ben Sizer wrote: I've installed several different versions of Python across several different versions of MS Windows, and not a single time was the Python directory or the Scripts subdirectory added to the PATH environment variable. Every time, I've had to go through and add this by hand, to have something resembling a usable Python installation. No such problems on Linux, whether it be Mandrake/Mandriva, Fedora Core, or Kubuntu. So why is the Windows install half-crippled by default? I just rediscovered this today when trying to run one of the Turbogears scripts, but this has puzzled me for years now. +1 It is a pain for me because it is something I need to remember to do maybe once a year or less. It seems best practice with Windows is to throw away the machine every 2 years - so much crap gets automatically installed in places and ways not solicited I'd think only cybermonks get away clean. That the Python install is a good citizen in this regard is noble, but does it really make a difference in regard to the overall Windows installation? And is that difference worth the recurring pain of not having Python on the path automatically? There must be hundreds of programs on the PATH of the machine I type on, its ugly. And lets not even talk about the Registry. Time to throw away the machine. That's what I get for being a cheap slut for any interesting program.

Re: merits of Lisp vs Python
No programmer who learned Lisp ever gave up before he learned Lisp.That would be the obvious retort, but my observation was empirical, so I am afraid you need numbers, not word games. You seem awfully hostile, by the way. Won't that make it harder to conduct an intelligent exchange of value to lurkers? I wonder, how many people gave up trying to learn Lisp because the language was too hard for them to read? Anyone like to bet that the number was more than zero?Sorry, no one ever discovered Lisp, decided it would be great for programming, started learning it and then gave up because they could not handle the syntax. Uh. Clearly no one would be dumb enough to admit it in front of the entire usenet world, right? - Mr. NoOne P.S. I am still going to get back to it when I get some time, really. LISP seems intriguing and superior, almost a magical Rubik's cube waiting for me. I just stumbled across Python in the meantime and code started flowing - I got distracted. I have CL ( Scheme) on all my machines awaiting my focus I'll join the flock any day now. :-) I've just been busy. There is a cost to learning and I've not had the spare change to date. But New Years resolutions need to be made: I could get up a couple hours early and spend some quality time with CL, do a daily hour jog, and eat a really heathly breakfast. Writing myself a note on this. P.P.S. Undoubtedly not learning a syntax either means not enough time was put in or the student lacked proper intelligence. This will always bias the significance of learning syntax as a factor in choice of language to be under reported. cheers -- http://mail.python.org/mailman/listinfo/python-list

Python -- (just) a successful experiment?
Raise your hand if you think the best technology wins! For those of you with your hands in the air, tell me: if Python is so good, why has PHP achieved such greater adoption and mindshare? Why do web scripters still cling to their Perl, even in corporate environments? Why hasn't Python made inroads against Java? Why is Ruby, and Ruby on Rails, getting such strong play? Are these better programming languages, or is it other factors? On a whim I installed Ruby on Rails today - pretty much a one-click deal. It was a very slick (Windows) installation, as it automatically figured out and downloaded dependencies - there was no question it was properly installed, and I ended up with a couple IDEs for Ruby, examples, etc. Markedly better than installing Python - no contest - and this downloaded a useful and easy to employ application, with a clear path to show me how to use it. As I perused the tutorial like documentation, I realized I wasn't anxious to jump into the language (Ruby), but I saw that I could certainly achieve a quicker success putting together a web application with RoR than with (take your pick: Perl, Lisp, Java, etc. etc.) If my mind wasn't appreciative of the Python language, though, Ruby would have hooked me right there. While I perceive that the future of the language Python is in good development hands - well debated, and thoughtfully strategized; the Python accoutrements can be lacking. Imagine, if you will, a new car, that does 0-60 in 2 seconds, 60-0 in .2 seconds, has a top speed of 185 mph, corners on par with an F-1 car, costs no more than a Volkswagen Passat... but comes without tires or seats, and you have to install the electrics and brakes yourself. Sure, car geeks are going to love it, but you just are not going to see that many at the grocery store, or doing car pool duty, and no garage really works on them much... forget about finding parts, you have to make your own replacements. I am not saying Python is that car, but I do think that Python, as opposed to Python the computer language specification, is done a great disservice by the lack of certain accoutrements. I do not know if there are features of the language (specification or philosophy) which thwart the development of the complementary items, but I firmly believe that the lack of them is a factor in Python's ho-hum adoption rate. A good computer language is great, but it pales in comparison with what can be done with such a language. What is missing? Maybe: -- Automatic dependency handling -- Tightly coupled GUI package (tightly coupled ~= Pythonic) -- High level IDE (i.e. intuitive drag and drop GUI builder) -- High level database framework (perhaps a mature, killer Dabo) -- Powerful web framework as good as the language (and simple enough for the PHP guys to use) -- Etc. Applications like Zope and Plone help drive more people toward the language, though the competition is stiff. Dozens of competing half baked tools/applications... they just confuse people and take up their time with decision paralysis, though they may be fun to write. Is it wrong to appreciate Python as a language, but want to have the nice accoutrements we see in some competing languages?

Re: Just remember that Python is sexy
I often can't remember that to remove spaces from a string whether it's strip() or trim(), and when finding patterns with the re library whether it's find() or search() and when iterating over key, values of a dictionary whether it's items() or entries(). But then I remember that Python is sexy. It is sexier to strip() than to trim(). You do a strip search() not a find() search. And you remove items() of clothing and not entries() of clothing. Genius!

I didn't come across any illuminating discussion via Google, thus my question here (though it may be a neophyte question.) I am interested in the workings under the hood of Python's access of files. What is actually happening at the various stages when I create a file object and read it? (1) f = file(C:/GuidosParrot.txt,r) (2) hesjustsleeping = f.read() At (1) have I loaded the file from hard drive into RAM when I create the file object? What does this object know and how did it find it out? At (2) am I loading the file contents into RAM, or just assigning what is already in RAM to a variable? Where is the work split between the OS and Python? I assume the OS is responsible for presenting the file to Python, so perhaps the OS assembles this file from the blocks on disk and loads it into RAM at the time the file object is created? Or would the OS simply have pointers that can assemble the file, and pass those pointers to Python? Perhaps I've answered my question and the under-the-hood mechanics are handled on the OS side, and Python is just making requests of the OS... My brain-teaser: What I'd like to do is read the last ~2K of a large number of large files on arbitrary servers across the net, without having to read each file from the beginning (which would be slow and resource inefficient)...

Re: OT: MoinMoin and Mediawiki?
Paul Rubin wrote: What I'm getting at is I might like to install MoinMoin now and migrate to Mediawiki sometime later. Anyone have any thoughts about whether that's a crazy plan? Disclaimer, I am neither using Moinmoin nor Mediawiki, and don't really have your answer. From what I read, Mediawiki stores each page as wikitext in a MySQL database; wikitext is a mixture of content, markup, and metadata. It seems essentially what you'd need for migration is a mapping function and I do not know how complex the mapping between the systems would be. I could imagine migrating from Moinmoin to Mediawiki via a script looping through the Moinmoin files in a directory, modifying a copy of each, and storing them in MySQL. I suspect it's less painful to just start with the wiki you want to end up with, but if you're going to migrate between the two, won't Python come in handy! ;-) Eric Pederson http://www.songzilla.blogspot.com ::: domainNot=@something.com domainIs=domainNot.replace(s,z) ePrefix=.join([chr(ord(x)+1) for x in do]) mailMeAt=ePrefix+domainIs ::: -- http://mail.python.org/mailman/listinfo/python-list
Re: The Industry choice
(the gravity model). On a decision making basis there seems to be an aspect of it that is binary: (0) either give in to gravity and gain shared advantage as part of a massive object, or (1) choose an alternate location far enough away not to be much affected by the force of the massive objects, and try to build mass there. I suspect Python is a (1) in that regard, but I may be wrong. Gravity as a model of technology adoption appeals to me as I've been thinking about cosmology a fair bit, and I have grave suspicions that much of the universe's dark (and green) matter is in Redmond.

All of them still rely on Tcl for crucial products. All of them also have employees who sincerely wonder, Tcl? Isn't that dead? I offer this as a counter-example to the belief that Adop- tion by a heavyweight necessarily results in widespread acceptance. -- I think the adoption of computer languages is quite complex, but one useful metaphorical model may be gravity, e.g. the clumpy universe of stars, with gravity working on different scales to shape the overall distribution of matter. Adoption by a heavyweight may have some effect if that force is allowed to operate on other bodies, but the overall distribution of mass is complex. In the practice of business, companies generally find a need to consciously limit methodological diversity as they grow in size. Control is usually made more centralized, but becomes more distant from the atom (programmer writing code) as the firm grows large, and entropy becomes the enemy, lower level entropy a source of uncertainty and risk. If so, there is some legitimate reason for trying to standardize on tools (i.e. programming languages). Less sophisticated business minds may latch onto the notion of gains from economies of scale, which is usually an easy sell (and good route for a fast career rise) but an overly simple optimization. Not to say that such restrictive mindsets and policies are inevitable, but they seem the prevailing wind. Preserving intellectual diversity and innovation may be critical to a big company in the long run, and allowing the use of (for example) Python would seem very in tune with those goals. It might be nice if it was widely understood (in IT) that Python was a language any competent programmer could pick up in an afternoon, such that Java, C, and Perl shops would not be concerned about the need for their staff to learn a new language.

Re: PHP vs. Python
Paul Rubin did say: For sites that get less traffic than that, they only reason they need to scale if they're written in Python is that Python is too slow. Asked earnestly: is there a feel or quantification that Python is slower than PHP in network applications? If, so, I am wondering if it is because of the traction PHP has in the web community leading to possibly tighter integration with (e.g.) Apache. My beloved Python-oriented webhost doesn't currently support Mod-Python due to concerns about unknown security risks, and without that one carries the interpreter start-up burden for each invocation, as I understand it. Speed in a server-client environment does concern me a bit because 100+ hits per second would be the minimum realm of success for the web app I am building in Python (I do not foresee using PHP, so maybe I would convert everything to C++ if I had to, but I really would not want to have to...) In everything I have done so far, Python's speed has been quite satisfactory, and I always remember the loud complainings in the MySQL forum about SQL queries that take seconds, minutes, days... only to end up magnitudes faster when someone points out the folly of the code or table set-up. Not sure if the OP is considering Python v.s. PHP on the server or on the desktop (PHP isn't web only, except by common use); they are very different use cases.

Re: Python mascot proposal
Since the word 'Python' would bring -some- sort of snake associations, I thought of combining snake and Monty Python symbolic, like making a snake wind around a giant foot, or adding long mustache and an english hat to a snake or something in that manner, or even put a snake into a holy grail heh. But then again, I'm not sure if there'll be no copyright issues. But surely only you and I and the other Pythonistas will recognize a Norwegian Blue when we see one. Might be hard to get away from the snake, as was noted, its a level or two easier mental association than MP. Logo? Maybe a Norweigian Blue on is back, one fut in e air, wit a snake ead off to is ide, grinningly wit a char-grin? es not dead!

Re: PajamaScript
Jerome (aka evil tofu) advised: I wrote something called PajamaScript. Basically, it parses a text file and looks for pj tags. Then it calls python to handle the scripting. Why learn another language when you already know Python? html head titleThis is fun!/title /head body The Date is pj module=misc function=zdate / .br The Time is pj module=misc function=ztime / .p pj module=database function=generateTableOfResults / /body /html PajamaScript then calls the function zdate in module misc and the output replaces the tag. This is not really tested in any production system, just a proof of concept I did for a project that never materialized. In order to access cgi variables, you can use the cgi module or any other python module! Would this be useful to anyone? Every tool has a use! Offhand it occurs to me this might a simple, well organized structure for a cgi environment, though I wonder if the extra level of processing might make it a little slow. Ought to be other uses too... I _do_ think the pj tags and the title PajamaScript is brilliant marketing. Highest kudos! [PajamaScript beats PyTxtParse2ModuleExecEnviron.py !] Any functioning examples of its use?
