You are confusing dynamic typing with weak typing. Weakly typed languages (such as BASIC perform) such implicit conversions. However, Python is dynamically and strongly typed. With dynamic typing, the type information resides with the actual object and not with the name referring to it. That simply means that the type cannot be determined till the object is actually created (i.e till runtime). But once created, the object does have a type. So you will need to explicitly convert yourself. In this case with int_value = int(string_value) Ravi Teja. -- http://mail.python.org/mailman/listinfo/python-list

In most cases, carefully examine why you need native code at all.

Unless your application is explicitly low level, native code is not worth bothering with. thanks, I'll check out psyco's documentation, since unfortunately the scripts will be run on a Windows box, and using a compiler other than VC++ is not an option... 1.) mingw works quite well for writing Python extensions. 2.) ctypes is a great way to incorporate native code.

Re: What would be the best way to run python client in the background
The reason for the a seperate persistant check is because it will be used to enable software to be installed in whole lab of PCs but only allow a predifined number to run the software at any time one time. And then when a user stop using the software a licence will become available to for someone else on the same or another PC to use the software. The reason that the process of the software being check is not used is because it will be used for software written by other people. I hope this makes what and why a little clearer. Let me know if you think that I have misunderstoood you. Hmm... I don't have experience with such architecture personally. The software being managed must have some sort of dependency on the license manager if the manager is to be external. I don't know how you can reliably manage external programs that are decoupled from the license manager. You can however create a plug-in of sorts if the other authors would be willing to incorporate it without much work to them. I mostly explored license management in Delphi apps. Since Delphi is/was a Shareware favorite, it has quite a few open source / commercial components available to manage such licensing, usually with trivial effort from the component user. You could take a look at them (http://www.torry.net/quicksearchd.php?String=sharewareTitle=No). Some of them might even compile on Lazarus to expose them to Python. By large, the culture of Python is open source and such expertise may not be common place here.

Re: code is data
I don't think that distinction is very meaningful. As a programmer I have to understand both. I understand the Python compiler well, and it gives me reasonably good feedback when I get things wrong, and it has a lot of flexibility along several orthogonal lines. We're talking about programming languages, so it's useless to consider a cognitive perspective without considering the compiler perspective. As some one who has followed your excellent articles, posts and tools over the last many years, I don't doubt your expertise at all. I admit I am not be entirely looking at this as a programmer. I am working in informatics for the last few years. At least in this domain, it is useful to seperate the perspectives. Sort of like designing a functional language based primarily on mathematical abstractions rather than imperative realities. Yes! Once the implementation is underway, the practical realities are unavoidable but they interfere in thinking, otherwise. I understand you, but it's very unclear to me how you can make a thin layer that's not horribly leaky or stunted. In my experience one or both are likely in DSLs, and the result is horrible and only useful as a toy. I am not making this up out of thin air. There is already an implementation, Logix, which allows you make thin layer DSLs on top of itself (which in turn sits on top of Python). It did not fly but I could not technically fault it (except maybe that it is not very optimized at the moment). Maybe with your better understanding of language implementations, you can. I understood the distinction you were making. But you were also speaking generally about generally programmable syntax, and I don't think that's a good idea, and it's very unclear how that mixes with Python. You can always do: model = make_model( my funny syntax ) And you actually get something that can be a close peer to normal Python code. But if you are talking about Python and some novel syntax interleaved, then the details seem to matter a lot, because the implementation is substantial and potentially invasive. NO! I have a feeling that you are interpreting me as a language radical. I do not think that Python syntax should have too many novelties. Currently Python feels a cohesive whole. A well designed entity rather than something that evolved by accretion of features like Perl. With active attempts to prune inconsistencies for that end (Python 3000). And I value all that. But Logix does not add ANY new syntactic constructs to Python. There is a special import function that imports a macro supporting Python language variant module where one can create special syntactic constructs. I am quite satisfied with the macro capabilities of Logix. But I am just grumbling that the Python community does not find macros interesting. But without enough users, it simply dies away. -- http://mail.python.org/mailman/listinfo/python-list
Re: code is data
Or... maybe to be more specific, the hard work later on goes into *code*. If you are enhancing your model, you do so with methods on the model classes, and those methods don't effect the DSL, they are just code. You create some raw XML in the beginning, but quickly it's just a matter of gluing those pieces together, using functions instead of DSLs, and that's just code. That doesn't look that much better. How do you create it programmatically? I know how to pass a variable to CharField(maxlength=200); can I pass a variable to char length 200 just as easily? Can I use **kw? Can I read it from a CSV file and construct the class that way? Maybe, but only by recreating all the native patterns that I can infer easily looking at the Django class. I am looking at it from the cognitive perspective. You are looking at it from the compiler perspective. I think you are talking about full blown DSLs like SQL which try to be self contained for a given domain. The ones I am referring are only thin layers on Python. Words are great. Python is light on symbols, and that is good. Agreed. When I came to Python from Perl, I loved the clean syntax. Scalars, arrays, hashes occur too frequently in Perl code that using symbols to denote them causes more noise than cognitive assistance. On the other hand, using symbols to denote an occational special construct is helpful (as in decorators). Even the Lisps stick to an incredibly homogenous syntax (far more homogeneous than Python) to make macros feel familiar. Yes! The parser friendly, everything is a list syntax does help. I did consider that to be an essential feature to enable dynamic macros. However I changed my mind when I saw Logix macro syntax. Constrained context is a step backward! How do you add methods? How do you do looping? How do you write *code*? If you aren't going to allow those things, then just make a parser and build the structure from the file, and make it a DSL implemented entirely external to Python. That's completely okay, though in my experience it's not very satisfying for something like a model definition (see MiddleKit for an example of an ORM that doesn't use Python code). I agree that constrained context is a step back in terms flexibility. But it is a strategic step backwards, in this case to trade for representational benefits. The extent of constraints is a judgement call. And proof of utility can only be emperical. However I think that you are seeing my sample differently than I meant it. I did not mean to create a special syntax file that would be parsed as a text file such that it would loose all the benefits of Python. It is just a thin layer over Python code for specific representational benefits.

I have listened to the arguments against Macros in Python and the ones that struck home were the argument for maintainability: Without macros, Python is Python. Statements do what you expect. Yes! I heard those arguments too. And I am not convinced. Static language programmer: Lack of static typing removes the necessary safeguards. The code is more error prone. Objects have behavior that is not obvious. Dynamic language programmer: Really? I don't seem to have any more bugs than in my statically typed code. And my code is compact and reads better. I don't want to go back. No to macros proponent: Macros introduce a lot of potential for abuse. Code will be worse to read than Perl. Macros proponent: Really? We have been doing macros for decades. We all think our code is better for macros, not worse. We are not going back. I just don't get it. Don't we often invoke the We are all adults here argument. Writing a macro is not as simple as writing a function. Sort of like metaclasses. Many will stay off them. Those that really need them will walk that extra mile. Don't we all believe that Simple should be possible. Complex should be doable And the argument against DSLs altogether: Make Python your DSL! If you design your own DSL before long you start to embellish it with more statements or data types and before long it becomes complex. If you used Python from the beginning then you would have a community for support. Python has a low cognitive overhead. But it not a DSL by definition. No language can be. The idea is that when the domain changes, a DSL should be driven by the new domain as warranted. In other words, driven by the problem, not the tool. I don't want a DSL. I want a language that allows me to make my DSL based on it. That means I don't loose the community connection. I can still use all the rich libraries in my DSL. I like Python for its indentation syntax, sensible semantics and readability. I invested a lot of time in Python. After much language hopping, I settled with Python. I like the community and the code base available for it. The libraries just seem to be designed at the right level of abstraction for me (as opposed to say, Java). When I need to do something, I know where to go. But all this ties me to the language tightly that I cannot change.

You blogged on Django. Let's use that. Don't you think model creation
in Django can be represented better, given that it is done often
enough?
Let's take an example from the official tutorial
from
http://www.djangoproject.com/documentation/tutorial1/#creating-models
class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('date published')
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(maxlength=200)
votes = models.IntegerField()
I don't use Django and I made this up quickly, so please don't pick on
subtleties.
@Poll:
question: char length 200
pub_date('date published'): date
@Choice:
poll - Poll
choice: char length 200
votes: int
The following is my rationale. Annoted variables, symbols and code
layout visually cue more efficiently to the object nature than do
explicit text definitions. Of course, this is only sensible when there
aren't too many of any of those. In that case, the cognitive cost of
notation outweighs the representational cost of text.
Representational minimalism is troublesome in general code (ala Perl),
but not so in a DSL where the context is constrained.
I would also like to symbolize field types since they occur so commonly
in a definition file and only a few of them are commonly used. I admit
though that I find the code below a bit visually jarring and I might
use something else. But it serves to illustrate the point. I chose the
respective symbols based on their colloquial use and association with
the field types.
@Poll:
$question: length 200
%pub_date('date published')
@Choice:
poll - Poll
$choice: length 200
#votes
Since you are on thread and are a prominent and involved member of the
Python community, I would like it if you (or any such other) can
provide feedback on the rest of my previous post rather than be
dismissive by just a small portion of it. Perhaps, that will give me
some insight how these language design decisions are rationally made (I
am not strictly a programmer by profession, much less a language
designer).

The idea is that we now have a fast parser (ElementTree) with a reasonable 'API' and a data type (XML or JSON) that can be used as an intermediate form to store parsing trees. Especially statically typed little languages seem to be very swallow-able. Maybe I will be able to reimplement GFABasic (my first love computer language, although not my first relationship) someday, just for fun. Then there are things like cTypes (calling functions from native DLL's) and PyPy (implementing Python in Python). All this taken together, to me it starts looking like we're now entering a territory that traditionally was exclusively in the Lisp domain. Yes, Python had eval and exec for a long time already, and metatypes and generators are having some strange unexplored possibilities too, but the day will come soon (and at last when PyPy is reaching execution speeds close to cPython) where Python will be able to swallow smaller languages, and finally it will be able to swallow its own tail, like Lisp but then more powerful (because of the widely used standard data types and the code exchange between languages that that makes possible). Your thoughts please. I don't share your optimism at all. Most of the things you mentioned have existed for long. Just because some of them are now included in the standard library isn't going to change things drastically. Installing them earlier was never hard at all. People like to call everything with the lightest semblence, a DSL. That gives the feel that the language is more powerful. Ruby people do it all the time. Python cannot be called a DSL language until, creating them is a natural language feature (like Lisp). And that does not seem to be happening anytime soon. Boo for example allows you to write new constructs with it's AST library. It still cannot be called a DSL language.

Don't be too harsh on it though. It is a language built for the
JVM/CLR. The author perhaps intended the library to be natural to the
users of the respective SDKs regardless of its' aesthetics and it
explicitly seems to provide a unified API for Java and .NET. Of course,
that is nothing new. Many languages have interchangeable backends for
these platforms these days but there seems to be a specific focus on
that here. The syntax does resemble Java/C#, which is also important if
you want buy in from the Java/C# crowd.
But semantically it is a proper functional language. The features may
not attract Python users who might prefer Boo/Jython/IronPython. But it
does offer something to disillusioned Groovy users.
But on the other hand, there are some neat features even for Python
programmers.
Tail recursion
Pattern matching
Currrying
Macros
Concurrency
Native XML support
Of course, you can get by without some of these in Python with
workarounds, libraries or hacks.

I love python, and I like it more everyday. And with the advent of Pypy, its future looks brighter than ever. But I also find very interesting these new options that are coming up. Although I'm not a professional programmer (not even a serious aficionado), I love to be able to translate my python skills very easily to .NET through Boo, for example. I even find it more appealing than Ironpython, because it was created from the ground up to take advantage of the CLR. On the other hand, porting pure python to .NET is in many aspects like trying to fit a square on a circle (I don't know if this sentence makes sense in english...). Because many of the design choices taken by GvR back in the early nineties were surely conditioned by the platform he chose to write python, which is the c language. The good thing is that python is having a lot of influence in these new languages. As far as I could see, even C# 3.0 is showing up some pythonic traits.
