I'm thinking of something in a config file like this ...
ssh_dropin = {exec: 'putty.exe -ssh %s@%s', args:['auser','somehost']}

You might want to look at Schevo (http://schevo.org), an ODBMS and
application development framework. Schevo builds on some of the
concepts introduced in Pypersyst, and can use Pypersyst as its backend
storage, but it can also use ZODB and Durus (and it is easy to switch
between backends). Schevo provides schema evolution and migration
features, enforces referential integrity and field constraints,
enforces unique indexes (whether single field or multiple field keys),
etc. All you have to do is describe your objects using a simple syntax
such as this snippet from a weblog application that we are putting
together as an example:
class Author:
"""Authors write posts."""
name = f.string()
password = f.hashedValue()
email = f.string()
_key(name)
_icon('.apps.kuser')
def __str__(self):
return self.name
class Post:
"""Posts contain content posted to the weblog."""
slug = f.string(doc='The short name that appears in the URL.')
title = f.string()
published = f.datetime()
author = f.entity(allow=Author)
excerpt = f.memo()
content = f.memo()
_key(slug)
_icon('.filesystems.desktop')
def __str__(self):
return self.slug
Schevo might not be quite ready for your particular needs, but the
situation you describe is the target for Schevo. While most of our UI
work has been with Qt, our next focus is on Nevow, which we have used
in the past on a predecessor to what is now Schevo. I've used Quixote
in the past, but I'm not sure how easy it would be to use it as the UI
for a Schevo app. Most of our short-term efforts are going to be
concentrated on Nevow and Plone for web applications, and Qt for GUI
apps (and hopefully wxPython at some point).
Matthew Scott and I will be giving a Schevo presentation at PyCon on
the subject of "Developing Database Applications With Schevo". You can
read our outline at http://schevo.org/doc/pycon2005/proposal.
Good luck with your project.

PyCrust is only a shell, not a full-blown IDE, so it likely lacks things that you were looking for. But it certainly does have history, multi-line command recall, and cut/paste options with and without the leading prompts. In fact, the default Copy command (Ctrl+C) strips out the prompts, and the Copy Plus command (Shift+Ctrl+C) retains the prompts. If you select the Session tab you'll see the entire command history, without prompts and without the responses from the Python interpreter.

Re: - E02 - Support for MinGW Open Source Compiler
Wow! I must say, I'm less than impressed with the responses so far. I know Ilias can give the impression that he is just trolling, but I can assure you he is not. At least, not in this case. ;-) So in an effort to make some headway, I'm going to try to summarize the current state of affairs. The bottom line is that compiling C extension modules on the Windows platform for Python 2.4 is, today, a royal pain in the ass. Period. Here's why. The main challenge is that extensions must be compiled using the same runtime dll as that used by the Python interpreter itself. The official Windows binary installation of Python 2.3.5 and its predecessors was compiled with one MS product, which was fairly easy to support with minGW, but Python 2.4 was compiled with the newer .NET compiler. Unfortunately, compiling extensions for Python 2.4 with the free MS tools is not trivial, as evidenced by Mike Fletcher's very thorough document on the subject: Python 2.4 Extensions w/ the MS Toolkit Compiler http://www.vrplumber.com/programming/mstoolkit/ In addition, there are some unresolved licensing questions concerning the .NET runtime file for extensions (msvcr71.dll): http://mail.python.org/pipermail/python-dev/2005-February/051393.html There have been extensive discussions about these issues on the Python-Dev mailing list over the past couple of months (mostly in December, but continuing to the present - see http://mail.python.org/pipermail/python-dev/2004-December/thread.html as a starting point), which seem to have fizzled out or at least haven't resolved much. The discussions made reference to work that has already been done to allow Python to be compiled with minGW: pyMinGW is a patch to Python source that aims to get Python to compile under MinGW http://jove.prohosting.com/iwave/ipython/pyMinGW.html I've not seen any commentary on the quality of this patch, so that doesn't appear to be the reason it hasn't been officially adopted. Reading all the threads from Python-Dev has not enlightened me at all as to what the underlying reason is for not adopting these changes. Maybe there are good reasons, I just couldn't find them, and I'm usually pretty good with Google. A few of you have mentioned that minGW is not an optimizing compiler on the Windows platform, whereas the MS .NET one is. If anyone has information on the performance differences, I'd really appreciate being able to see it, particularly as it applies to Python 2.4. Now, we get to the essence of my particular situation. I've got a project that includes some Python extensions written in C. My users (who are Python developers, but not necessarily hard-core types) need to be able to work out of their local Subversion checkouts. This includes locally compiling these extensions as necessary. I'd like this to work with Python 2.4, and be as painless as possible on my users. I can't expect them to purchase a .NET compiler or go through a bunch of configuration changes. So far, I haven't figured out a good way to support this. I'm open to suggestions. I suspect that my needs are very similar to those of the original poster. Perhaps the issue is in part a matter of minGW catching up with the new MS compilers. My understanding of and experience with Python 2.3.5 and its predecessors has been that Python itself didn't need to be recompiled with minGW, since extensions compiled with minGW linked to the same C runtime dll. So if minGW had support for msvcr71.dll then maybe this problem goes away with Python 2.4 as well. If anyone can shed any light on this situation, it would really help me out. Thanks. -- Patrick K.

Re: [EVALUATION] - E02 - Support for MinGW Open Source Compiler
Stephen, I appreciate your responses. Maybe "school bullies" was an exaggeration on my part. At the same time, I'm not sure it is good for the Python community to expect everyone to roll up their sleeves and hack at something to make it work. (And I don't mean to imply that you hold that opinion. But far too many others *have* expressed that.) It's a marketing issue as much as anything. Why is Apple doing so well? They make everything simple. Now the techies will argue that they make some things too simple (like the iPod), but it's hard to deny that simple things that work consistently without any fuss have a broader appeal with the public at large. I think the same applies to developers. Not every programmer is willing to go through a lot of pain and effort just to get something simple to work. I, for one, am willing to go through that pain to save users of my product (who happen to be developers) from having to do the same. But I don't think any less of my users. I'm as lazy as they are. I like simple things that work consistently without any fuss too. :-) Patrick K.

Okay, I think we are pretty much talking about the same thing. My problem is not that I'm unable or unwilling to purchase a good compiler. My problem is that I don't want to make it a requirement of my users. The twist is that my users will be working out of a Subversion repository that includes source code for extensions written in C. Those extensions need to be compiled, and the code changes too frequently for me to want to deal with supplying compiled binaries. So I'm looking for options for Windows users who do not have, and are unwilling to get, a Microsoft compiler. For some users, minGW is an attractive option. For those who want to use minGW, I'm trying to establish whether or not minGW is a viable option, particularly for Python 2.4. I was under the impression that there were possible advantages to compiling Python itself using minGW, but that that required some patches that hadn't been applied to Python (for reasons unknown to me). Said patches are available here: http://jove.prohosting.com/iwave/ipython/pyMinGW.html I'm also under the impression that there are possible disadvantages to compiling Python itself with anything other than the Microsoft's optimizing compiler, such as performance. But I haven't seen any numbers on that, so I don't have information one way or the other. It may also be the case that minGW can now correctly compile extension that link to the newer runtime used by Python 2.4, but that wasn't always the case. If that's true, that would eliminate the primary reason for wanting to compile Python itself with minGW, though philosophical differences with MS might motivate some to want to avoid the MS compilers altogether. Perhaps the only thing that's a mess is my understanding of the situation. But even if that's the case, I don't think I'm alone, based on all the threads I've read over the past couple of days. ;-) Thanks in advance for any help anyone can offer to reduce my confusion.

In my defense, the threads I was referring to were prior to this thread and did not include the two snippets that you've quoted. Besides, there *was* additional work that needed to be done, specifically adding the python23.dll or python24.dll to the \mingw\lib directory, as you mentioned in one of your previous posts.

If you put yourself into the shoes of someone who decides to use a Python product that requires compiling, and that product contains C extensions that also need compiling, you'll see that it doesn't matter whether or not that individual has actually written a single line of Python themselves. If the compiling process is not easy, then that user will be forced to fiddle with nitty gritty details about which they'd rather remain ignorant. On Linux, I've installed and used/compiled products in a variety of languages in which I've never written a single line of source code myself. In most cases the process works fairly well. When it doesn't, I'm forced to fiddle with nitty gritty details about which I'd rather remain ignorant. The result is usually a good deal of frustration and anger on my part. On Windows, most users are used to installing precompiled binary packages, rather than compiling from source. When you do have to compile from source, it often requires you to fiddle with nitty gritty details about which you'd rather remain ignorant.

I don't recall saying that it was their fault, but if I gave that impression I apologize. I'm mainly reacting to those individuals who keep claiming that things couldn't be any simpler and that there is no problem.

Actually, I think this group is potentially huge in comparison to the current users of Python. It's just that they aren't currently represented in the Python community. Look at the PythonCard project. I was involved in the early stages of its formation (that was when I wrote PyCrust, which was incorporated into PythonCard). A great deal of the interest in PythonCard was from hobbyists, VBers, old HyperCard developers, etc. These folks were not your typical Python programmers. They just wanted a simple tool that they could use to create simple applications. Now what if PythonCard started using some C source code as part of their project? They would either have to provide binaries, or they would have to make it easy for their developer community, many of whom are on Windows, to be able to compile C extensions for Python. If they couldn't make it easy, they would risk alienating many of their supporters. So my only point is that by making it easier to use C extensions, we have an opportunity to make Python more attractive to a broader audience that includes hobbyists and folks that do not want to pay for commercial C compilers. And I think there may very well be more C code in typical projects with all the cool tools getting used, like Pyrex and such. [snip] The rest of your message provided great information.

optparse question
Up until today, I never needed to pass any arguments to a Python program. I did all the requisite reading and found that I should use optparse instead of getopt. I read the documentation and since the words "simple" and "easy" often appeared in the examples and documentation, I just knew that it would be a snap to implement. Problem is that all I wanted to do was pass a one flag to the program "-d", for to enable debug mode. Several hours later I gave up after optparse complained about every variation I tried. What does it take to pass single parameter to a program? http://docs.python.org/library/optparse.html stated that programs always have options. Is that so? What about "dir /s"? getopt resolved my immediate need, but I would like to know how one could use optparse to extract out the options from something like "dir /s /b". -- http://mail.python.org/mailman/listinfo/python-list
Re: optparse question
If you mean with "/" as the option designator instead of "-": there doesn't appear to be a documented way of doing it. You would have to do some social engineering on the users to get them used to doing "dir -s -b". In any case I thought the number of Windows users who know how to fire up a Command Prompt window was diminishingly small ... you actually have users who know how to use commands like "dir /s /b"? I used dir /s /b as a trivial Windows example. I use Windows for personal use but Ubuntu for work and programming. Personally, I use dir /s /b all the time on Windows since the /b option finds files *much* faster; maybe 10x or 100x faster but I didn't get out a stopwatch. -- http://mail.python.org/mailman/listinfo/python-list

Re: optparse question
I had no idea people were going to get so upset that I used a Windows example and go off on a tear. Nobody is upset, and nobody has "gone off on a tear". The point about the "Windows example" is that the docs say in a close-to-screamingly- obvious manner that /options are not supported, no matter what religion uses them. It was not, and still is not, apparent what you really wanted. We're all patiently waiting for you to rephrase the question(s). Sigh. I used an incorrect example (I sincerely apologize to the world for that egregious error on my part). I''m totally cognizant that the documentation states '-'' or '--' need to be used for flags. The question was it possible to add a simple flag like 'd-' to optparse with no other parameters? I'm guessing from the vitriolic diatribes here that the answer is no. To those who wrote that no one uses command line windows and no one uses 'dir /s /b' command is totally irrelevant. I'm writing a proprietary program used solely by my company. Not everyone writes programs for the same target audience as you do. The program is written in Python on Ubuntu.

Just like any other type of errors : testing, testing, and then add some more tests. I haven't gotten into unittesting. I've just started learning Python. It also dawned on me why my original question is a bit lame. Python supports default arguments; something that is new to me. How could lint possibly know the correct number of arguments passed to it?

Array of dict or lists or ....?
I can't figure out how to set up a Python data structure to read in data that looks something like this (albeit somewhat simplified and contrived): States Counties Schools Classes Max Allowed Students Current enrolled Students Nebraska, Wabash, Newville, Math, 20, 0 Nebraska, Wabash, Newville, Gym, 400, 0 Nebraska, Tingo, Newfille, Gym, 400, 0 Ohio, Dinger, OldSchool, English, 10, 0 With each line I read in, I would create a hash entry and increment the number of enrolled students. I wrote a routine in Perl using arrays of hash tables (but the syntax was a bear) that allowed me to read in the data and with those arrays of hash tables to arrays of hash tables almost everything was dynamically assigned. I was able to fill in the hash tables and determine if any school class (e.g. Gym) had exceeded the number of max students or if no students had enrolled. No, this is not a classroom project. I really need this for my job. I'm converting my Perl program to Python and this portion has me stumped.

I don't understand why I need a database when it should just be a matter of defining the data structure. I used a fictional example to make it easier to (hopefully) convey how the data is laid out. One of the routines in the actual program checks a few thousand computers to verify that certain processes are running. I didn't want to complicate my original question by going through all of the gory details (multiple userids running many processes with some of the processes having the same name). To save time, I fork a process for each computer that I'm checking. It seems to me that banging away at a database would greatly slow down the program and make the program more complicated.

Ah-hah! That's how one uses groups. It's beautiful. I couldn't find

At first, I thought that using RE's in Python was going to be more
difficult than Perl. A lot of my Perl code makes heavy use of RE
searching and substitution.
I will never, ever write another line of Perl code as long as I live.

question regarding list comprehensions
I have written chunks of Python code that look this: new_array = [] for a in array: if not len( a ): continue new_array.append( a ) and... string = "" for r in results: if not r.startswith( '#' ): string =+ r It seems that a list comprehension could clean up the code, but I seem to have a mental block on list comprehensions. I've read up a lot on this subject in my books and on the Internet and for whatever reason, I'm having problems with this idiom (if that's the correct expression). I've made a number of attempts to solve this on my own but I keep getting errors. Could someone please tell me how I could convert the above code to something more elegant but readily understandable? Finally, if someone could point me to a good tutorial or explain list compressions I would be forever in your debt. -- http://mail.python.org/mailman/listinfo/python-list

Think of a for-loop: for x in (1, 2, 3): x Creates x=1, then x=2, then x=3. It doesn't do anything with the x's, but just creates them. Let's turn it into a list comp, and collect the x's: [x for x in (1, 2, 3)] [1, 2, 3] for x in (1, 2, 3): 2*x+1 Creates x=1, then evaluates 2*x+1 = 3. Then it repeats for x=2, then x=3. Here it is as a list comp: [2*x+1 for x in (1, 2, 3)] [3, 5, 7] for x in (1, 2, 3): if x != 2: 2*x+1 Here it is as a list comp: [2*x+1 for x in (1, 2, 3) if x != 2] [3, 7] You can use any sort of sequence inside a list comp, not just a tuple. [c.upper() for c in "abcd"] ['A', 'B', 'C', 'D'] You can nest list comps: [y+1 for y in [2*x+1 for x in (1, 2, 3)]] [4, 6, 8] Advanced: you can use tuple-unpacking: [(y,x) for (x,y) in [(1,2), (3, 4)]] [(2, 1), (4, 3)] and also multiple for-loops: [(x,c) for x in (1, 2) for c in "abc"] [(1, 'a'), (1, 'b'), (1, 'c'), (2, 'a'), (2, 'b'), (2, 'c')] That last one is close to: for x in (1, 2): for c in "abc": (x, c) Thank you. I think that clears up the mystery a bit. I added your note to my snippets file. When I have a situation that I can't resolve, I'll ask with the specifics.

Question about scope
I have a Globals class. In it, I have a variable defined something like this: remote_device_enabled = bool In one module, I assign True/False to Globals.remote_device_enabled. Once set, this value never changes. In another module, at the top after the imports statements, I tried this: from Globals import * RDE = Globals.remote_device_enabled This way, I thought that I could just use 'if RDE:' Within the functions, however, I get a different value. What am I misunderstanding?

lint for Python?
I've been searching for a good multi-module lint checker for Python and I haven't found one yet. Pylint does a decent job at checking for errors only within a single module. Here's one of my problems. I have two modules. In module one, I have a function: def foo( host, userid, password ): pass In module two, I call that function: foo( userid, password) lint doesn't find that error and it won't be caught until it's called while the program is running. I don't want that error found at 3AM. I've never used a language that didn't catch that type of error. I'm quite surprised that Python is being used by a number of major companies. How you catch these types of errors? I've spoken to tech support at Wing and they weren't aware of a multi-module lint but they're considering putting their own lint into their IDE.

screen resolution.
I can get the width and height of the screen, but I can't seem to use the

Don't change the account IIS is running under - that is a pretty big
security issue waiting to happen.
Change the authentication model for the web site to Basic, then logon as
you. That will cause any execution to be in the security context you are
expecting.

(at least under windows - don't know where it'd be in linux/elsewhere) When I deleted it, the next invocation of boa worked fine. Good luck! Pat -- http://mail.python.org/mailman/listinfo/python-list
Relative Imports
Hey guys, I know this is a really stupid question, but I've tried googling and nothing came up. I also tried IRC, but it was too crowded and I didn't get much useful information. I'm using Python 2.5 on WinXP, and I'm trying to do a relative import. Here's the package structure A/ __init__.py aneededmodule.py [some more modules] B/ __init__.py anothermodule.py anothermodule.py needs to use aneededmodule.py; package A's __init__.py looks like this: from aneededmodule import somestuff My problem is that when anothermodule tries to import ..aneededmodule or ..somestuff (because somestuff was imported into __init__), I get a ValueError: Attempted relative import in non-package. What's my problem? This seems like something very trivial, but I've never had to use python for a project of this size before, so I've never dealt with this. Thanks for your help, -Pat -- http://mail.python.org/mailman/listinfo/python-list
