Business models that try to assign it one are doomed to fight an uphill battle against market forces. +1 QOTW. -1 That quote confuses the *cost* of duplicating software (which is close enough to zero) with the *value* put on the software by the market (the users). We can see that, for example, Ben Finney himself puts quite a lot of value on software such as emacs. Just recently Ben wrote (paraphrased) that he valued emacs because although he wasn't a Lisp programmer, other programmers had already produced many fine emacs tools that let him be a more productive developer. Now Ben is agreeing with the statement that he doesn't value software, that he considers emacs and other such tools mere commodities and is indifferent to which he uses, or even whether he uses any at all. That's clearly untrue, and I can only imagine it is because Ben doesn't understand what it means for a product, service or thing to have no market value. No value is not the same as priceless, and I imagine Ben would agree that freedom to modify the source code of emacs is virtually priceless. Should distribution costs rise (say, because the Australian government's compulsory web censorship plan accidentally block all free software -- it must be warez if it's free, right?) then would it really be inconceivable that people in Australia who valued emacs over (say) Microsoft Notepad would be willing to pay for reliable, uncensored copies of the software? Plenty of people pay for free software. Some of them pay with money, some of them pay with development effort, some of them with both. Unless my memory is playing tricks on me, I believe that Ben himself has purchased Ubuntu CDs with real money; and if he hasn't, I can assure you that his employer has. I can only imagine that what Lawrence was trying to say was something on the lines of this: open source software reduces the ability of vendors to extract monopoly rents from software by turning each software application itself into a commodity. It's not just that there are a thousand different text editors from a thousand suppliers that Ben could use, but that there are a thousand suppliers entitled to distribute emacs itself, and competition between those suppliers ensure that the cost of emacs approaches the marginal cost of duplication and distribution, which is essentially zero. (The corollary of this is that to avoid such commoditization, software vendors need the government to enforce an artificial monopoly on each product. That's not necessarily a bad thing, although it often is.) It's not as snappy as saying that Ben and others like him don't value software, but it's more accurate. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

It allows you to visually create UIs that run unmodified on Windows, Linux and OS X. You can learn about it at http://dabodev.com -- Ed Leafe -- http://mail.python.org/mailman/listinfo/python-list

Stef Mientki: it's just Object Pascal , which is inferior to Python. They are quite different languages, you can't compare them in a simple way. Delphi is statically typed, and compiles very quickly producing small exes; algorithmic code can run a hundred times faster than Python code. There are lot of people still that think that a statically typed language is safer. Delphi is kinda old, so today there are better languages than Delphi (like D), but when Delphi 2-3 was out, there weren't many other languages with IDEs at its level, especially for programs with a nice GUIs plus interfaces with DBMSs.

In your code, index = () means it is a tuple. IIRC, it should be a
dictionary. For that, index = {}. This is the one causing the following
error in your code,
if not index.has_key(value):
AttributeError: 'tuple' object has no attribute 'has_key'
You can not use has_key over a tuple object.
But where is the indentation error ? I see nothing like that in the error
message.

If you define index as a dict instead of a tuple, you'll stop getting
that error -- but I'm afraid it still won't do what you want. Are
you trying to get a phonebook in which the values of the original
phonebook are the keys of the new one -- and the values are lists
(both 'sandeep' and 'titu' have the same number)? If so, try this:
def invert(table):
index=dict()
for k,v in table.items():
if index.has_key(v):
index[v].append(k)
else:
index[v] = [k]
return index
You had mentioned something about indentation error... If you'll
look at your definition of invert(), you can see that 'return index'
is inside the for loop -- which would cause a return before the
second time through the for loop. By dedenting (is that a word?) so
'return' falls directly below 'for', the for loop would have been
able to run to completion before returning.
Hope this helps,
Michael

You don't need to set any environment variable to run Python. (Perhaps
PYTHONPATH, but *only* if you put modules into non standard places)
import posix
Traceback (most recent call last):

That's ok: there is no module named posix on Windows, it is only
available on Unix systems.
I've rearranged a bit your example. Write the following into a file named
test.py - use whatever editor you like (even notepad):
---begin file test.py---
def invert(table):
index = {}
for key in table:
value = table[key]
if not index.has_key(value):
index[value] = []
index[value].append(key)
return index
phonebook = {'sandeep':9325, 'amit':9822, 'anand':9890, 'titu': 9325}
print Phonebook, phonebook
inverted_phonebook = invert(phonebook)
print Inverted phonebook, inverted_phonebook
---end file test.py---
Then open a console window, change to the same directory where you saved
test.py, and execute:
python test.py
You should get:
Phonebook {'titu': 9325, 'amit': 9822, 'anand': 9890, 'sandeep': 9325}
Inverted phonebook {9890: ['anand'], 9325: ['titu', 'sandeep'], 9822:
['amit']}

Hi Sandeep.
As you are working with Python on Windows, I would suggest that you
install the Python for Windows extensions from here:
http://sourceforge.net/project/showfiles.php?group_id=78018
It includes a very good application called PythonWin. Once installed,
PythonWin will be available under Python in your Start menu.
If you run PythonWin, File/New gives you the option to create a new
Python script. To begin with, you can save into the Lib folder of your
Python installation (probably C:\Python25\Lib). I usually add my
initials at the front of the script name to differentiate my scripts
from the standard ones if I put stuff in Lib.
You should be able edit your PYTHONPATH variable in PythonWin - see
the Tools options (though, now I look, my installation actually has a
bug in this function), or alternatively, you can add a folder to your
PYTHONPATH environment variable in RegEdit (if you know what you're
doing).
I hope this helps.
J.

Re: python on window
That should have been: You should be able edit your PYTHONPATH variable (should you need to)... Gabiel is right, it's not usually required. -- http://mail.python.org/mailman/listinfo/python-list
Python Shell window
Is their any way of setting wear the Python Shell window appears on the screen when I run my program? I am testing a full screen program with no Window Frame on a comp with 2 monitors and I have to keep pressing the Window Key to bring the Shell to the front and then moving it manually to the other screen every time I restart the program. I would like it to just appear on the other screen from the start. Any ideas -- http://mail.python.org/mailman/listinfo/python-list

1. Do you really want the CMD prompt to show up? If not, rename your
file from .py to .pyw and it will be hidden. You'll miss all of the
STD* streams though.
2. Find the window and move it to the right place. Here is a script I
use to launch PuTTY (which has the unfortunate problem of 'hiding' its
title bar below my 'Start' bar which I keep at the top of my screen).
It's convient for me to launch PuTTY from this script but I don't see
any reason why you couldn't add this code to your main function and
find the errand CMD prompt and move it.
(For this you need the win32 extension installed)
import win32gui,os,sys,time
command = rstart putty -load %s
def moveWindow(hwnd, ignored):
x = win32gui.GetWindowText(hwnd)
if x.find('PuTTY') = 0:
left,top,right,bottom = win32gui.GetWindowRect(hwnd)
if top 30:
width = right - left
height = bottom - top
win32gui.MoveWindow(hwnd,left,top+30,width,height,1)
try:
p1 = sys.argv[1]
except IndexError:
#print you must provide a valid machine name
p1 = opus
os.system(command % (p1,))
time.sleep(1.0)
win32gui.EnumWindows(moveWindow, None)
HTH..

python-text window vs. game/graphics window
Hello, group! I am asking anyone who is knowledgeable about entering text into the text window while a game/graphics window is running (am using pygame). I have asked this on the 'tutor' mailing list and no one could/would answer it. I am making a space invaders clone for my Python Teacher's birthday, and so obviously can not ask him for help! Even the debugger wouldn't shed light on the situation, due to when it happens: I am trying to make a high score list. If you do not score high enough, the list displays in the text window (fine), and you can type y/n in the game window for a new game. If you DO make the high score list, it prompts you to enter your name on the text window (and hit enter), and displays the updated score list (great). However, when I click back to the graphics window, the whole thing closes/shuts down/crashes. For the life of me I cant figure it out. I have looked at the order of my steps, I've tried to follow it through piece by piece, and like I said I tried to use the debugger to step through it - but since the game just closes out, it doesnt tell me anything. 1. How can I stop this crash from happening? I have copied and pasted the game over section of my code below, and am attaching the entire code to the email, in case that would be helpful. 2. I'd REALLY like to make it display the high scores/prompt for user name on the game/graphics window, not in the text window, anyway - and that would eliminate the problem it seems to have when using keystrokes in the text window and then trying to switch back to the game window. (it's not a click-specific issue, alt-tab does it too). I apologize for the newbie nature of this question to a more advanced list, but I have tried everything else I can think of and am at my wits' end. The 'deadline' (birthday) is in a week and I'm stuck. I'd appreciate any comments or suggestions you might have, in as simple of language as you can offer them, ha ha. I *am* new to python, and so my code may not be so elegant. But I hope you can read it enough to see what I'm doing wrong or possibly just offer suggestions for displaying it all in the graphics window and avoiding the problem altogether. Thank you so much for your time and ideas!
