Re: [Tutor] Data hiding in Python.
My vote is, no, not worth the trouble. It's Java / C++ / static-typing / put-the-client-in-a-straightjacket-so-they-don't-touch-anything thinking. Heh...and don't forget the king-pin of them all, C#. Between private, public, protected, internal, and protected internal I lose track of what I was originally doing and end up contemplating the meaning of what if another programmer wants to use this creation of mine instead of doing what I set out to do... I'm with Kent on this one...definitely not worth the trouble to bastardize Python like that... As a side note, does anyone have a good argument for access level controls like C#? I personally think it's a waste of time (much like C#/ASP.NET...my apologies to any .NET fans out there...), and honestly the arguable margin of security that access modifiers provide is outweighed by the cons, in my opinion. (And usually what programmers end up doing is creating service methods that allow access anyways, so the margin of security is lost). Thoughts?

Yeah, I would have to agree with you there. I hadn't considered that angle... But multiple languages compiling to a common runtime all with a single class library is powerful medicine... I would argue the only real innovation provided by .NET is just that: the ability to produce and consume project components from different languages. I have to say I'd still prefer Java development over .NET, but that's probably more personal issues with Microsoft than language implementation. I recently used Python for a relatively large project for a Linux scripting class (the professor was kind enough to allow any relatively common scripting language (i.e. available on our Linux server...heh)) and I have to admit, I'm much more productive with Python than with virtually any language I've used before.

[Tutor] GUI with Designer
Wow... SPE is in the Gentoo repository as well. I've been looking for something to replace Eric, so thanks for the tip, Chris! I'll check it out. Jonathon Chris Hengge wrote: Well, I use SPE which comes with wxGlade and XRC. For the small amount of gui I've done with python I think SPE offers the best IDE coder experience (coming from a VS world). The tools make sense to me. wxGlade is a GUI designer written in Python with the popular GUI toolkit wxPython http://en.wikipedia.org/wiki/WxPython, that helps you create wxWidgets/wxPython user interfaces. At the moment it can generate Python, C++, Perl and XRC (wxWidgets' XML resources) code. XRC(wxWidgets' XML resources) is nice because it allows you to abstract your interface design (think of any program that uses XML to format skins). Overall, I think everyone using python should give SPE a try, even without gui programming its a great tool for writing code. It's free, and written in python using wxPython.. Stani (the Dev) is a great person for helping out with questions on using his package, he puts out regular updates and fixes. He's got some help from a few other people so its packaged in .exe, .rpm and standalone .zip formats. It's also on the standard repo's for Ubuntu.

For example, if the file is not executable, you would execute it as follows: $ python shebangtest.py As you found with `which python`, python is in /usr/bin, so executing the script is actually $ /usr/bin/python shebangtest.py Therefore, the shebang line needs to be as follows: #! /usr/bin/python Then once the script has execute permissions (man chmod), it will run as expected. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] move forward in arbitrary direction
The something you're stuck on is the angle the triangle has rotated, measured in radians. If the concept of radians is not familiar, then here's a quick review: There are 2*pi radians in a complete circle (about 6.28) There are 360 degrees in a complete circle 1 radian is approximately 57 degrees Going by radians, 0.0*pi is pointing to the right, 0.5*pi is pointing down, 1.0*pi is pointing to the left, and 1.5*pi is pointing straight up. Keep in mind that python has a math function radians(x), which converts x degrees to radians. If you use that, you can use degrees instead and convert on the fly. (i.e. something to the effect of: math.cos(math.radians(degrees)) would give you the change in vector[0]). If you would rather use radians, keep in mind that the python math module also has the pi constant, which is pretty self explanatory... Hope that helps you...

My understanding is that an iterator is basically a facade` pattern. If you aren't familiar with patterns, a facade` pattern basically makes something really easy to use or convenient. Yes, you can do it by hand, and many times that is indeed the preferred method, but sometimes it's easier to use an iterator...particularly if it isn't a special case.

[Tutor] Zipfile and File manipulation questions.
Chris Hengge wrote:
I chose the way I used the names because to me...
outFile = open(aFile.lower(), 'w') # Open output buffer for writing.
= open a file with lowercase name for writing.
it is implied that aFile is from the zip, since it is created in the
loop to read the zip..
outFile.write(zFile.read(insideZip)) # Write the file.
= write what is read from inside the zip file.
I guess for declaration it isn't very clear, but thats what comments are
for?
My naming was purely for my ease of mind.. I personally care less about
what I call it when I declare, as to how it logically flows when I go to
use it. I'm sure this is considered poor method, but once I declare a
method I tend to never need to change the declaration, just how I use
the info... I hope that makes sense.
Even if you're the only person that EVER lays eyes on that code (and you
inherited Perl code, so I assume someone will eventually take this code
over) it's vital to use names that are clear and concise. If you
disagree, put your code away in a locked box, then re-read it after six
months and see if it makes perfect sense.
As Kent said, this is quite a minor issue that shouldn't be paraded, but
I have been on the receiving end of code such as:
int a;
if (a == 0)
{
/* do something interesting */
}
else
{
/* do something less interesting */
}
(Sorry for the Java-ish flair...Java happens to be on my mind at the
moment...)
Even if I was there when the code was written, how could I know what a
means a month later without digging back through to see how it's used?
(and worse, a was used for conditional testing in this specific
example (i.e. on/off conditions), so a boolean would have done MUCH
better). Commenting can only help so much...the code must speak for
itself at some point. (Yes, I know this is an extreme example, but it
happens all the time).
Something like this is much more readable:
boolean fileExists;
if (fileExists)
{
/* do something interesting */
}
else
{
/* do something less interesting */
}
I'm not complaining, because afterall it's up to you to write the code
you're comfortable with (because you're not working on a team, that is),
but a friendly suggestion on naming conventions (especially when you can
refactor in most IDE's today) could go a long ways to helping you build
readable code that is easier to maintain.

Yes, that is what I meant. One minor quibble, I think I would keep

as the name in the zip, since that is what it starts as, and use a new

example zipPath and fileName. I think that would make the code a little
clearer but it is a very minor point.

[Tutor] executing with double click on linux
I'm afraid I don't have enough experience with Gnome to answer your questions, Alfonso. I will share what I know, though. If you could, run this: $ gnomevfs-info yourfile.pyc | grep MIME and see what it says? (If it gives you nothing back, then you need to register a MIME type for .pyc files. http://www.gnome.org/learn/admin-guide/2.14/mimetypes-modifying.html is the official Gnome documentation on how to accomplish that task) You should get a MIME type of application/x-python-bytecode. If that checks out good, then my suggestion would be to place all of your python code in a good place (/home/user/scripts or the like) then create a desktop shortcut pointing to: python /home/user/scripts/targetScript.pyc. If my memory serves me well, when you create a desktop shortcut you can tell it what command to run as well as what commandline arguements to pass to the program. Split it up accordingly. I've tested that out in idesk running on fluxbox, so I can't guarantee how well it will work under Gnome, but it's worth a try. Also, if your script doesn't have a GUI, you'll need to point the desktop shortcut to: xterm -e 'python /home/user/scripts/targetScript.pyc' (use your favorite terminal, of course...) instead of simply python /home/user/scripts/targetScript.pyc, or you'll lose the output. (I checked against idesk/fluxbox while monitoring with Conky...my CPU shoots to 100% on a py script that I wrote that builds Markov models from the words in a given dictionary file...(yes, I was quite bored the day I wrote that...), so I know the script is indeed running even without a terminal to output to). If you create the shortcut in that fashion, you *should* be able to run whatever python bytecode you want... Hope this helps, and let me know how that works out for you...

I have tried to associate python to the .pyc (first time I executed it there was no programm associated), but it doesn't work.

As such, bash attempts to execute them as binary (ELF, etc...), which obviously won't work. If you really need to have double-click/execute functionality, consider writing a small shell script to execute the .pyc file for you. For instance, let's say you have a python script foo.py and a compiled python script foo.pyc. If you attempt to run foo.py from the shell and you have a proper header (i.e. #!/usr/bin/python), then bash can execute the script. I'm assuming that GNOME has similar functionality (I prefer Fluxbox to either GNOME or KDE), which allows your .py files to execute directly. .pyc, however, even with a file association, fails to launch...on my system, I get this error: $ ./foo.pyc bash: ./foo.pyc: cannot execute binary file bash recognizes the file as binary, but it fails to launch as an ELF binary (or whatever you're set up to run). To fix it, simply write a shell script as such: code #!/bin/sh python /home/me/scripts/foo.pyc /code Name the script whatever you want (i.e. foo.sh) then run from the commandline: $ chmod 700 foo.sh This gives the script read/write/execute permissions for the owner of the script...if you require read/write/execute/etc...for group or all, change 700 to whatever you need. (i.e. 755 for rwxr-xr-x permissions) (Alternatively you can right click on the shell script and set permissions graphically...whichever you prefer) Now, you should be able to double-click the script (or preferably a shortcut to the script on your desktop), which will launch the compiled python module for you. If this seems like a lot of work, then perhaps you could write a shell script to automate the task of creating the shell script and setting permissions each time you create a new .pyc...doh?

If you attempt to run foo.py from the shell and you have a proper header (i.e. #!/usr/bin/python), then bash can execute the script. I'm assuming that GNOME has similar functionality (I prefer Fluxbox to either GNOME or KDE), which allows your .py files to execute directly. .pyc, however, even with a file association, fails to launch...on my system, I get this error: $ ./foo.pyc bash: ./foo.pyc: cannot execute binary file bash recognizes the file as binary, but it fails to launch as an ELF binary (or whatever you're set up to run). To fix it, simply write a shell script as such: code #!/bin/sh python /home/me/scripts/foo.pyc /code Name the script whatever you want (i.e. foo.sh) then run from the commandline: $ chmod 700 foo.sh This gives the script read/write/execute permissions for the owner of the script...if you require read/write/execute/etc...for group or all, change 700 to whatever you need. (i.e. 755 for rwxr-xr-x permissions) (Alternatively you can right click on the shell script and set permissions graphically...whichever you prefer) Now, you should be able to double-click the script (or preferably a shortcut to the script on your desktop), which will launch the compiled python module for you. If this seems like a lot of work, then perhaps you could write a shell script to automate the task of creating the shell script and setting permissions each time you create a new .pyc...doh? Hope this is a satisfactory answer...and if anyone knows something I have overlooked, please let Alfonso and I know. Jonathon Thank you for your answer. __ LLama Gratis a cualquier PC del Mundo.

[Tutor] OT: Book(s) about linux
Hello Bernard... Just to give you a pointer about Linux: If you're new, Fedora and Ubuntu are both relatively easy to learn, but powerful (I've never used Ubuntu (or Debian, for that matter), but I hear that Ubuntu is a really great distro). Stay away from Slackware and Gentoo, at least until you've had the chance to familiarize yourself with Linux. I made the mistake of attempting a stage 1 Gentoo install on a PII machine with hardly any experience. (Fortunately, the PII was so slow that I had time to read the manual completely before each step). It booted up fine when I was done, but it was rough (even with extensive documentation ). I'm not saying that Slackware and Gentoo are useless, as both are *extremely* powerful OS's (Gentoo is my favorite OS other than OpenBSD). They do require quite a bit of knowledge just to get them installed, however, and therefore are not good choices for someone just beginning with Linux.

But I want to get hands down with Linux, and am looking for a book or two on the subject. I'm looking for information about installation, configuration, optimisation, and management of the Linux OS. If you are new to Linux, you're likely to be best helped by a book that matches your distribution, e.g. Ubuntu Linux or Ubuntu Unleashed. (Not to push you to Ubuntu; I'm running Fedora myself.) These books provide shallow coverage of everything and will give the background needed to make good use of the system documentation. They will also point you to yum, synaptic, smart or whatever package management system makes sense with your chosen distribution. The package managers greatly simplify system administration. There are books devoted to packages: SSH, Sendmail, DNS/Bind, Apache, Samba, etc. so you may need to get additional books depending on how you use your computer. Linux in a Nutshell (mine is 5th edition) provides a useful reference. There are also books like Linux Debugging and Performance Tuning which are more system oriented. Moving to the Linux Business Desktop is useful for finding your way among all of the available desktop applications. Linux is a pretty broad subject so there's a huge range of books from which to pick.

[Tutor] from string to variable name
By string variable that contains a name that I want to use as a variablename do you mean something like this: myString = rotationalSpeed rotationalSpeed = 4500 ?? In Python a dictionary is an excellent solution to this problem. The only other way to accomplish this (to my knowledge) is in PHP (not trying to steer you away from Python, just giving some info): var myString = rotationalSpeed; $$myString = 4500; echo $rotationalSpeed; results in 4500. This is called variable variables in PHP and it can get hairy if done in a sloppy manner. I'm going to make the same recommendation that Luke did. Dictionaries are powerful structures. I recently wrote a Python script to parse an English dictionary file and build Markov models out of the words contained in the file (no, it wasn't for school, or work, or anything...I was just really, really bored). Rather than declaring an int to hold the frequency information for every letter, digram, and trigram possible (a total of 18,278 declarations), I used the letter, digram, or trigram as a key into a dictionary. Now I can do simple lookups by individual letters, digrams, or trigrams and see the frequency information without having to reference thousands of variables, and as an added side effect, only the letters, digrams, and trigrams that actually occur require storage.

You won't let us ask you 'why' you want to do this, but I'll ask you: Why don't you want to use a dictionary? Do you want to know if it's _Possible_ just so you'll know, or do you actually want to use this for something? If you just want to know if it's possible, I believe it is. But consider: if you don't know the variable name until runtime, how are you going to refer to the variable later in your code?

[Tutor] Random Variable at root
Hugo, You need to create an instance of the Root class before you can call rootState in your final print statement. Your code doesn't do this. A class is merely a template, something like blueprints to a house. For you to be able to unlock the front door (for instance), you need to actually build a specific instance of the house first. 313 Hillcrest Lane and 4214 Willowbrook Drive might be two houses that have the same blueprint, but maintain different states from each other because they are different instances of class House. To make this work, remove the final print statement and replace it with this: # instantiates (builds) a copy of the Root class and names it root root = Root(0) print The character state at the root is %0.f % root._rootState Note the change to the end of the print statement. Your code has rootState, mine has root._rootState (the specific instance of Root, followed by the dot operator, followed by the attribute or method you are trying to access). I'm a bit confused as to whether you intended _rootState to be a copy of the *original* value passed in, with rootState maintaining a copy of the *current* value, or if that is a typo. Please elaborate. Hope this helps clear up confusion (as opposed to creating more...heh). Jonathon halamillo wrote: Hello, I'm a really-green-to-python Biology Grad Student.

[Tutor] Java: (and python ?) nearer measles than coffee
Hrmmm...my opinion is that you shouldn't waste your time with Java (sorry to any Java coders on this list). It's entirely too automated for my tastes (automatic garbage collection, transparent pointers, etc...). To quote an unknown author who was quite the anti-OOP programmer, it made me want to throw a java.f***ThisException. So why, might you ask, am I bothering learning Python? Well, at first I was looking for a powerful scripting language to prototype with. You know the routine...whip up a quick and dirty version 0.1 and let the customer see what's in store, test layouts, algorithms, design ideas, etc... Reason I use Python #1: But then I noticed something. Python runs on my wife's Windows machine...and my Linux machine...and my OpenBSD machine...and insert your favorite operating system here...etc... The real catch for me was OpenBSD support. Find a thorough java runtime for OpenBSD (I last looked probably a year or two ago, so correct me if I'm wrong on this), and perhaps I'll try it out, but until then, Python is my choice when I need code that will run on multiple OS's. Reason I use Python #2: I'm not trying to flatter anyone, seriously, I'm not...but this list is another reason Python has been a favorite of mine. Reason I use Python #3: I am a strong advocate of Open Source Software and the GPL. If Sun truly supported Open Source, then the OpenBSD team would have the specs for Java. Reason I use Python #4: If I want to code something in Java, give me a week. For Python, give me one night, perhaps two. I prefer getting done so I can move on, ya know? Anyways, those are the first few reasons I use Python. Jonathon Klaus Ramelow wrote: Sometimes I have also some - or more - problems trying digesting python and feeling totally blocked.

If this is indeed the case, then you need to replace the while fc statement block in your code. Your code is looking for f (i.e. 0 -9 for the example numbers above), in kl and ll. This explains why you can get the least common multiple (0), but nothing more. The solution would be to replace the entire while fc block with this: while (indexK c and indexL c): if kl[indexK] ll[indexL]:# kl contains a smaller number indexK = indexK + 1 elif ll[indexL] kl[indexK]: # ll contains a smaller number indexL = indexL + 1 else:# kl and ll contain the same number here both.append(kl[indexK]) if kl[indexK] ll[indexL]: # this block is needed so we # don't enter an endless loop... indexK = indexK + 1 else: indexL = indexL + 1 (make sure to declare indexK=indexL=0 somewhere before this block) The following print both statement would then output: [0, 660, 1320, 1980] Is this what you were asking for?

I've been playing around with some Pygame examples lately, and thought that I'd try writing the game in Python (I've been meaning to learn Python for years, but just never got around to it.) Today I started on writing the game. I've decided (at least for now) to call my version, LinePuzzle. For those of you unfamiliar with Chuzzle, here's the basic concept: There are individual pieces of different colors arranged on a grid. The pieces can be moved on a line either vertically or horizontally. The object of the game is to position three similarly colored pieces ajacent to each other. At this point the three pieces will disappear, and the pieces above them will fall to take their place. As the levels progress, locks are added so that the player cannot move a locked piece either horizontally or vertically. The game is over when no more pieces can be removed. I started my script by creating a class called LinePuzzlePiece which represents a single coloured piece. I wanted a random colour chosen from a list to be assigned to the piece, and then to prove that I had it set up correctly, I wanted to call a method that would print out the color of the piece. Here is my code: #!/usr/bin/env python import random import time import math class LinePuzzlePiece: This class defines a single playing piece for LinePuzzle def __init__(self): seed(time) index = int(math.floor(uniform(1, 10))) colorlist = [red, blue, green yellow, purple] self.color = colorlist[index] def printcolor(): print self.color mypiece = LinePuzzlePiece mypiece.printcolor I saved the script and made it chmod +x. However, when I run it, I get this: [EMAIL PROTECTED] ~ $ ./linepuzzle.py [EMAIL PROTECTED] ~ $ Now, I'm no expert, but I really think something should have been printed, if even a blank line.

When I first started with Linux, she was kinda iffy about it, but now she loves it. We've only used it since fall of 2003...
