Re: What is the most simple, quicket, yet most powerful python Web-Framework?
xkenneth a écrit : All, I'm trying to build a simple web application, but i still need things like sessions and Ajax. I tried to create a Zope product, but I honestly can't think of anything more cryptic. Indeed !-) I really don't enjoy learning all of the magic code and debugging an environment I have to study to know the slightest thing about. I'm looking for simple, fast, and easy. I'm both a manager and a developer, so I don't have a lot of time to try things out and see what fits best. I need a solution i can implement well and with a great deal of speed. My project is going to be rather simple, just some simple forms for setup/configuration, user management, I assume I'll need templates, Then I'd recommand Django: clean, easy to get started with yet still powerful, well documented, strong community. You'll also get some basic user management and simple yet very usable and useful automatic admin forms for free. I'd like to use Ajax or a similar technology to display orthogonal and polar graphs that automatically update. This is mostly orthogonal to the framework. For the DB backend I'm planning on using ZODB. ZODB is actually quite amazing, and after using it, I honestly can't think of a reason for using a SQL database. Having working experience with both the ZODB and various SQL DBMS, I can think of quite a lot of pretty good reasons to use a SQL database, and quite a lot of good reasons to avoid the ZODB unless you pretty well know what you're doing. Don't get me wrong: the ZODB is a pretty good piece of software, and there are some use case for it. But since you're talking about orthogonal and polar graphs - which to me implies lot of small, atomic, highly structured data -, I don't think an OODB would fit here. -- http://mail.python.org/mailman/listinfo/python-list

Thank you, Matt, for your valuable advice! I did try using ';' to issue three commands at once and it works! However, I have more problems with issuing ClearCase commands, which is what I am really doing. Under telnet, I could issue commands one by one, just as typing at the command prompt.

I always assumed you needed COMMIT() after adding new content to the database, not after every single query, but this perhaps indicate otherwise? No, you just need to be aware that the database module has probably started a transaction on your behalf and that, as John points out, for certain database systems in certain configurations, any repetition of the same query in the same transaction will produce the same results, thus avoiding the nonrepeatable read problem. Really, the rule is this: always (where the circumstances described above apply) make sure that you terminate a transaction before attempting to read committed, updated data. If you religiously perform a COMMIT (or ROLLBACK) after every query, you'll just create lots of transactions for no good reason. Paul -- http://mail.python.org/mailman/listinfo/python-list

Re: smtpd module
En Wed, 06 Feb 2008 05:36:05 -0200, Stefan Witzel
[EMAIL PROTECTED] escribi�:
the documentation of the smtpd module in the Python Library Reference
is very short, I think. Are there any examples available? Especially
I'm interested in the DebuggingServer.
Yes, the documentation is rather incomplete.
SMTPServer is an abstract class; it accepts local connections and handles
them, but doesn't know what to do with the received message. Subclasses
must override the process_message method to do something useful.
DebuggingServer is the simplest subclass; it just prints the received
message and nothing more, the message isn't delivered at all. Useful when
you want to test some program that sends messages but you don't want them
to be actually delivered.
PureProxy delivers the message to the upstream SMTP server (defined in the
constructor). By example:
localsmtpd = smtpd.PureProxy(('localhost',2500),('smtp.whatever.com',25))
asyncore.loop()
Then you (or your MUA, or any program, or a python script using smtplib)
can connect locally to port 2500 and send messages; they will be delivered
to smtp.whatever.com.
You can subclass PureProxy and pre-process the message before it is sent;
you could block some addresses, disallow attachments, add those annoying
disclaimers... MailmanProxy, by example, is a PureProxy subclass that
intercepts messages addressed to mailman and processes them directly.

Re: Multiple interpreters retaining huge amounts of memory
What objects need to be shared across interpreters? My thought was to add an interpreter number to the PyThreadState structure, to increment it when Py_NewInterpreter is called, and to keep track of the interpreter that creates each object. On deletion, all memory belonging to these objects would be freed. Thoughts? That won't work, unless you make *massive* changes to Python. There are many global objects that are shared across interpreters: Py_None, Py_True, PyExc_ValueError, PyInt_Type, and so on. They are just C globals, and there can be only a single one of them. If you think you can fix that, start by changing Python so that Py_None is per-interpreter, then continue with PyBaseObject_Type.

Professional Grant Proposal Writing Workshop (May 2008: Salt Lake City, Utah)
The Grant Institute's Grants 101: Professional Grant Proposal Writing Workshop will be held in Salt Lake City, Utah, May12 -14, 2008. Interested development professionals, researchers, faculty, and graduate students should register as soon as possible, as demand means that seats will fill up quickly. Please forward, post, and distribute this e-mail to your colleagues and listservs. All participants will receive certification in professional grant writing from the Institute. For more information call (888) 824 -4424 or visit The Grant Institute at www.thegrantinstitute.com. Please find the program description below: The Grant Institute Grants 101: Professional Grant Proposal Writing Workshop will be held in Salt Lake City, Utah May 12 - 14, 2008 8:00 AM - 5:00 PM The Grant Institute's Grants 101 course is an intensive and detailed introduction to the process, structure, and skill of professional proposal writing. This course is characterized by its ability to act as a thorough overview, introduction, and refresher at the same time. In this course, participants will learn the entire proposal writing process and complete the course with a solid understanding of not only the ideal proposal structure, but a holistic understanding of the essential factors, which determine whether or not a program gets funded. Through the completion of interactive exercises and activities, participants will complement expert lectures by putting proven techniques into practice. This course is designed for both the beginner looking for a thorough introduction and the intermediate looking for a refresher course that will strengthen their grant acquisition skills. This class, simply put, is designed to get results by creating professional grant proposal writers. Participants will become competent program planning and proposal writing professionals after successful completion of the Grants 101 course. In three active and informative days, students will be exposed to the art of successful grant writing practices, and led on a journey that ends with a masterful grant proposal. Grants 101 consists of three (3) courses that will be completed during the three-day workshop. (1) Fundamentals of Program Planning This course is centered on the belief that "it's all about the program." This intensive course will teach professional program development essentials and program evaluation. While most grant writing "workshops" treat program development and evaluation as separate from the writing of a proposal, this class will teach students the relationship between overall program planning and grant writing. (2) Professional Grant Writing Designed for both the novice and experienced grant writer, this course will make each student an overall proposal writing specialist. In addition to teaching the basic components of a grant proposal, successful approaches, and the do's and don'ts of grant writing, this course is infused with expert principles that will lead to a mastery of the process. Strategy resides at the forefront of this course's intent to illustrate grant writing as an integrated, multidimensional, and dynamic endeavor. Each student will learn to stop writing the grant and to start writing the story. Ultimately, this class will illustrate how each component of the grant proposal represents an opportunity to use proven techniques for generating support. (3) Grant Research At its foundation, this course will address the basics of foundation, corporation, and government grant research. However, this course will teach a strategic funding research approach that encourages students to see research not as something they do before they write a proposal, but as an integrated part of the grant seeking process. Students will be exposed to online and database research tools, as well as publications and directories that contain information about foundation, corporation, and government grant opportunities. Focusing on funding sources and basic social science research, this course teaches students how to use research as part of a strategic grant acquisition effort. Registration $597.00tuition includes all materials and certificates. Each student will receive: *The Grant Institute Certificate in Professional Grant Writing *The Grant Institute's Guide to Successful Grant Writing *The Grant Institute Grant Writer's Workbook with sample proposals, forms, and outlines Registration Methods 1) On-Line- Complete the online registration form at www.thegrantinstitute.com under Register Now.

Re: Broke my IDLE!
Just to clarify my earlier comment... IDLE (on Windows, at least) creates a folder called .idlerc in the current directory when it is called. If you amend the key bindings two files, config-keys.cfg and config-main.cfg are created. config- keys.cfg contains the amended key bindings and config-main.cfg contains the name of the key binding file if it is not the platform default. The config processing seems to happen in python_root/Lib/idlelib/ configHandler.py. Sorry for the inaccuracy in the first post, Cheers, Kev -- http://mail.python.org/mailman/listinfo/python-list

Re: Why chdir command doesn't work with client.get_transport() ?
Thank you, Matt, for your valuable advice! My application is converting (to sftp/ssh) a script which used ftp/telnet to load/copy/zip files with labels to/from a ClearCase server. ClearCase is a version control software similar to MS Source Safe or PVCS. The command 'ct setview aViewName' is just one of my commands which worked fine using telnet. If you don't type this command and type 'cd aDirNameInClearCase', it won't work. After typing 'ct ...', the prompt will be changed and the 'cd ...' command will work. Now my problem has been solved. I used the class channel's get_pty(), invoke_shell() and sendall() functions. Basically I used an interactive shell, so that I could issue commands one by one like using telnet.

Adding properties to an instance
Hi all, So I understand that properties belong to a class not an instance, but nonetheless I want to add properties to an instance. I have a class which when an instance is created runs some fairly complicated code and produces a set of names which I'd like to be able to access via properties. At the moment, I'm using something like obj.getvar(name) but I'd like to be able to write obj.name. (Note that they can't be just standard attributes because they only get computed when they are accessed.) I could generate functions like obj.name() but I want it to be obj.name instead. The solution I've come up with is to create a new class for each object which is just the real class with some extra properties, and then dynamically change the class of the object to this new class. This seems to work, but I wonder if (a) there is a nicer solution than the one I'll post below, (b) if there are any dangers or pitfalls of this approach. The obvious difficulty is with derived classes. At the moment, I'm insisting that a derived class has to call a makeprops() method to create the properties. It's kind of similar to this recipe: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/197965 but that recipe has a much simpler situation in which the properties and values are known at the time of the creation of the object (by contrast, I don't know what the properties are until the end of the __init__ method). Any thoughts? Code below to illustrate my approach. import warnings from operator import itemgetter class A(object): def __init__(self,**kwds): self._kwds = kwds self.makeprops() def __getitem__(self,i): return self._kwds[i] def makeprops(self): if not hasattr(self,'_madeprops'): self._madeprops = set() self._failedprops = set() class _A(self.__class__): pass for k,v in self._kwds.items(): if not k in self._madeprops and k in dir(self): if not k in self._failedprops: warnings.warn(Cannot create property +k+, already used in object +str(self),RuntimeWarning) self._failedprops.add(k) else: setattr(_A,k,property(fget=itemgetter(k))) self._madeprops.add(k) self.__class__ = _A class B(A): def __init__(self,**kwds): super(B,self).__init__(**kwds) self.makeprops() class C(A): def __init__(self,**kwds): self._kwds = kwds a = A(x=1) b = B(x=2,makeprops=3) c = C(x=3) print isinstance(a,A), isinstance(a,B), isinstance(a,C) # True False False print isinstance(b,A), isinstance(b,B), isinstance(b,C) # True True False print isinstance(c,A), isinstance(c,B), isinstance(c,C) # True False True print a.__class__ # class '__main__._A' print b.__class__ # class '__main__._A' print c.__class__ # class '__main__.C' print a.x # 1 print b.x # 2 print b.makeprops # bound method _A.makeprops of __main__._A object at 0x00A86810 try: print c.x # raises exception except AttributeError: print c has no element x c.makeprops() print c.x # 3 print a.__class__ # class '__main__._A' print b.__class__ # class '__main__._A' print c.__class__ # class '__main__._A' --- Dan Goodman http://thesamovar.net/contact -- http://mail.python.org/mailman/listinfo/python-list

Re: Adding properties to an instance
Here's one way of doing what you're asking... I would suggest using __getattribute__ and __setattr__ to dispatch the methods to the custom class you invent that holds all those properties. For example (I simplified your makeprops into __init__ just to keep the example short, but you can probably see the idea here..) class A(object): def __init__(self, **kw): class _PropHolder(object): pass for k,v in kw.items(): setattr(_PropHolder, k, property(fget=itemgetter(k))) self._custom_props = _PropHolder() def __getattribute__(self, attr): try: return getattr(self._custom_props, attr) except AttributeError: return getattr(self, attr) def __setattr__(self, attr, val): if hasattr(self._custom_props, attr): setattr(self._custom_props, attr, val) else: setattr(self, attr, val) def __delattr__(self, attr): if hasattr(self._custom_props, attr): delattr(self._custom_props, attr) else: delattr(self, attr) On 6 Feb 2008, at 12:06, [EMAIL PROTECTED] wrote: Hi all, So I understand that properties belong to a class not an instance, but nonetheless I want to add properties to an instance.

Re: Adding properties to an instance
Er, instead of getattr(self,...) you gotta do object.__getattr__(self,...) and same for setattr and delattr. Dumb error on my part. (Otherwise you get infinite recursion!)

Hi How do I get user defined attributes of a class? e.g Class A(object) : self.x = 1 -- I want something like: for userattrib in A.getAllUserAttribute() : print userattrib My question is, is there a builtin function, called getAllUserAttributes?

Are there any Python libraries implementing measurement of similarity of two strings of Latin characters?

A measure of 0 is that the inputs are the same. The more different the two strings are, the greater the resulting output of the function. Unfortunately, it's an O(MN) algorithm (where M=len(word1) and N=len(word2)) from my understanding of the code I've seen.

I'd suggest a small improvement: _A as a class name isn't very nice.
Replace the inner class statement with:

Ah yes, that's much nicer.
A problem with this approach is that instances aren't pickleable (perhaps
that could be solved using __reduce__)
I think because the properties can be computed from knowing the rest
of the data of the object, it would be safe when pickling to just
pickle a copy of the object with the __class__ changed back to A (and
then when you load it again, you can just generate the properties
anew). I haven't really thought much about pickling but it would
certainly be a nice feature to have.

MFC is the Microsoft Foundation Classes, used by many Windows
programmers to create applications. Mark Hammond, the author of
PythonWin, used them to build that.
I am hugely surprised to find that PythonWin apparently raises string
exceptions: this is an old programming technique, which should have been
removed from anything designed to run on Python 2.5. That is why you see
the message: it's only a warning, so you can ignore it. I am copying
Mark on this message in case he's unaware of the issue.
Don't be surprised if the ordering of the elements in a dict is
different between Python versions - a dict is an unordered collection,
and so the ordering of the elements isn't supposed to be predictable.
Mark Pilgrim probably used an earlier version of Python to prepare the
examples, that text has been around some time (though it's still good).
