Fredericksburg, VA ZPUG Meeting: November 9, 7:30-9:00 PM
Please join us November 9, 7:30-9:00 PM, for the sixth meeting of the Fredericksburg, VA Zope and Python User Group (ZPUG). Squid and Zope! Using Zope for newspaper publishing! The dangers of object oriented inheritance! Free food! * Andrew Sawyers will discuss using the open source cache server Squid with Zope, including a discussion of the O'Reilly book about Squid. * Allen Schmidt, Sr. Programmer for Fredericksburg.com - the website for the Free Lance-Star - will present on Using Zope for Newspaper Publishing. * Jim Fulton, CTO of Zope Corporation, will present an abbreviated version of the argument given in Clemens Szyperski's Component Software for why both inheritance and delegation (e.g. acquisition) cause tight coupling and therefore should be avoided except in special circumstances. * We will serve delicious fruit, cheese, and soft drinks. We've had a nice group for all the meetings. Please come and bring friends! We also are now members of the O'Reilly and Apress user group programs, which gives us nice book discounts (prices better than Amazon's, for instance) and the possibility of free review copies. Ask me about details at the meeting if you are interested. General ZPUG information When: second Wednesday of every month, 7:30-9:00. Where: Zope Corporation offices. 513 Prince Edward Street; Fredericksburg, VA 22408 (tinyurl for map is http://tinyurl.com/duoab). Parking: Zope Corporation parking lot; entrance on Prince Edward Street. Topics: As desired (and offered) by participants, within the constraints of having to do with Python or Zope.

Re: wxPython: updating style of StaticText from event generated by button
I would suggest you to take a look to the wxPython custom buttons; you can find them in the demo, under Custom Controls == GenericButtons. There you will find old style buttons, that can be simple buttons or toggle buttons (with up and down states). I have XP, and they look like old style buttons. Pff. Sorry, apparently I just completely missed that specific part of the demo although I've been using the demo all the time so far. :(. This is more a wxWidgets question that a wxPython one. However, quoting the wxWidgets manual: Yes, I had looked it up in the manual, but Please note that some styles cannot be changed after the window creation [...] is hardly the same as In general you *can not* change in runtime the style of a widget. Only a very limited subset of the wxPython widgets supports style changes in runtime right ;). Thanks for the great help! - Kees -- http://mail.python.org/mailman/listinfo/python-list

expanding dictionary to function arguments
I have a dictionary that I would like to expand to satisfy a
function's agument list. I can used the ** syntax to pass a dictionary,
but
this only works if each key in the dictionary matches an argument.
I cannot pass a dictionary that has more keys than the function has
arguments.
# Example 1 - This works:
# Prints hello world!
def foo (arg1='greetings', arg2='planet', arg3='.'):
print arg1 + ' ' + arg2 + arg3
args = {'arg1':'hello', 'arg2':'world', 'arg3':'!'}
foo (**args)
# Example 2 - This does not work:
# raises TypeError: foo() got an unexpected keyword argument 'arg4')
def foo (arg1='greetings', arg2='planet', arg3='.'):
print arg1 + ' ' + arg2 + arg3
args = {'arg1':'hello', 'arg2':'world', 'arg3':'!', 'arg4':'ignore'}
foo (**args)
As a practical application, I have a project where I have a config file
that defines a large number of keys and values. I read the config
file into a dictionary called options. I also have an API module with
many
functions that I want to call with arguments taken directly from the
options dictionary. The key names in the options dictionary match
the argument names of the functions in my API.
# The ugly, brutish way:
options = read_config (options.conf)
extract_audio (options['source_video_filename'])
compress_audio (options['audio_raw_filename'],
options['audio_compressed_filename'], options['audio_sample_rate'],
options['audio_bitrate'])
mux (options['source_video_filename'],
options['audio_compressed_filename'], options['output_video_filename'])
I know that the keys in my options dictionary match the arguments
of the functions in the API library, so I would like to do this:
options = read_config (options.conf)
extract_audio (**options)
compress_audio (**options)
mux (**options)
I created the following function to do what I am describing.
This isn't too bad, but I thought that perhaps there was some
secret Python syntax that will do this for me.
def apply_smart (func, args):
This is similar to func(**args), but this won't complain about
extra keys in 'args'. This ignores keys in 'args' that are
not required by 'func'. This passes None to arguments that are
not defined in 'args'. That's fine for arguments with a default
valeue, but
that's a bug for required arguments. I should probably raise a
TypeError.
if hasattr(func,'im_func'): # Handle case when func is a class
method.
func = func.im_func
argcount = func.func_code.co_argcount
required_args = dict([(k,args.get(k)) for k in
func.func_code.co_varnames[:argcount]])
return func(**required_args)
So, I now I can do this:
options = read_config (options.conf)
apply_smart (extract_audio, options)
apply_smart (compress_audio, options)
apply_smart (mux, options)
Neat, but is that the best I can do?
Yours,

And if anyone wants to take the responsibiblity to warn the general public that it is troll so innocent readers may not be tempted into one, at least do it privately or else it is doing exactly the opposite.

So far, it has been true on the files I have tried it on. Not too reliable then. 0x0100 is one of a number of unique start codes in the MPEG2 standard. It is guaranteed to be unique in the video stream, however when searching for codes within the video stream, make sure you're in the video stream! See, for example, http://forum.doom9.org/archive/index.php/t-29262.html Actually, one easy way (DVD specific) is to look for 00 00 01 e0 at byte offset 00e of the pack. Then look at byte 016, it contains the size of the extension. Resume your scan at 017 + contents of 016. Right. Glad that's the easy way.

Greetings! I am trying to make a multiplayer (no AI, 2 person) game of
tic tac toe in Python. So far it has been pretty simple. My only
concern is with the win checking to see if a person has won. At first
it looked like it was working, but now it sometimes assigns a win when
you enter an X or O (doesn't matter) on certain tiles (row 1, column 1
won't be an error, but row 2, column 3 will be...). If you can find
the problem, I'd be very thankful! Here's the code:
I see one of the reponses directs you to a web site about how to ask
questions and expect answers - there's some very good advice
there. Nonetheless, I'll give you the benefit of the doubt and assume
that you are _very_ new to programming. I hope I haven't redone your
homework for you, but if I have, I would suggest you don't submit my
answer, I think it might be recognised as not being your own.
The biggest problem with asking someone for help with a program like
this is that it's very large (not in and of itself a problem) and,
even to the most rapid glance, the program contains huge swathes of
essentially the same code repeated over and over with only tiny
changes. When I see that, all the warning bells start ringing.
My first hint would be that anytime you find yourself typing exactly
the same (or almost exactly the same thing) over and over, you are
probably doing something wrong. In your original code, you have a
whole section for handling player X, then you have virtually identical
code, for player O.
You should almost never need to do this. There are a couple of easy
ways to save retyping the same code:
1) create a function. The function body will have all the identical
code, the function arguments will indicate what's different between
the two sections. I think this is a hint from Kernighan and Pike
from a book dating back to the late 1960's - subroutines are used
to show what code has in common, the arguments are used to show
what's different.
or
2) put the duplicated code inside a loop and let the loop variable be
used to make the small changes. That's what I did in the hasty
rework of your program below.
Then, when we look at the code for a single player, you have 9
separate tests to see if a cell is occupied:
if row == 2 and column == 1:
if gameboard[3] != ('O' or 'X'):
gameboard[3] = ('O')
else:
print This cell is already filled.
turnnumber = turnnumber - 1
For each row and column, you know which cell to look at, so why have
tests for every possible input, when only one test will apply for any
given user input?
The cell you want is:
gameboard[3 * (row - 1 ) + (column - 1)]
so one test can replace 9. In reworking this, I calculate this
location once and save it as 'loc', since I'll be needing the location
later.
Then there's the question of the test if the cell is occupied:
if gameboard[3] != ('O' or 'X'):
This doesn't test if the cell contains an 'O' or an 'X', what it
actually tests is whether the cell contains an 'O'. The reason for
this is that Python sees the 'or' operator and tests if the left hand
side is True, which, since it is a string, tests if the string is
empty, which it isn't. Python, when given EXPR or EXPR returns the
left hand EXPR if it is True, otherwise it returns the right hand
expression. Also, since you know that unoccupied cells contain a
space, why not test for the cell containing a space, instead of
testing that it doesn't contain an 'O' and it doesn't contain an 'X'?,
no 'or' operator required? If you must use 'or', then you'd have to
write:
if gameboard[3] == 'O' or gameboard[3] == 'X':
print This cell is already filled.
The next point is the entire user input section. You have a while loop
waiting until the game is won, which gets the user input at the top
and goes through the entire rest of the code on every user input. It's
clearer to handle the user input within a smaller loop which runs
forever (while 1:) prompting for input and which uses the 'break'
statement to drop out of the loop when the input is valid. If I were
writing this myself, I'd probably extract it into a function, simply
to separate it from the game playing code.
You display the current board with a very lengthy print statement,
naming each cell to be printed and surrounding it with individual
']''s. But this is the sort of job computers do well. What you
actually want to do is print three lines, one for board[0] through
board[2], another for board[3] through board[5] and the last for
board[6] through board[8].
print [%s][%s][%s] % (board[0], board[1], board[2]) etc.
would work in three clearer lines, but we may as well let the computer
do the calculation of the indices using a for loop. A final pair of
improvements is to not type the [%s] 3 times, nor the name of the
board 3 times. We can get the format string using the * n notation:
'[%s]' * 3

No, you ALSO have to write ( ) [[parentheses]] after that. MENTIONING a

Too late: by having those parentheses there you've ALREADY called func1
at the time the execfunc dict was being built.
Suggestion: parenthesise differently to make tuples:
execfunc = { 'key1' : (func1, ()),
'key2' : (func2, args) }
now, something like:
f, a = execfunc[k]
f(**a)
will work for either key.

Eval or exec aren't needed. Normally you would just do...
execfunc['key1'](**args)
If your arguments are stored ahead of time with your function...
execfunc = {'key1':(func1, args)}
You could then do...
func, args = execfunc['key1']

Re: dictionary that have functions with arguments
[EMAIL PROTECTED] writes:
hi
i have a dictionary defined as
execfunc = { 'key1' : func1 }
to call func1, i simply have to write execfunc[key1] .
but if i have several arguments to func1 , like
execfunc = { 'key1' : func1(**args) }
how can i execute func1 with variable args?
using eval or exec?
Whenever you think should I use eval or exec for this, you should
*immediately* stop and think What am I doing wrong?.
Others have suggested using a tuple to hold the function and
arguments, and pointed out the mistake in your invocation.
Whenever you're thinking about doing an evalu with a fixed string, you
can replace it with a lambda. That looks like:
execfunc = dict(key1 = lambda: func1('hello'))
def func1(x): print x
...
execfunc['key1']()
hello
You can use the tuple format, and then use apply and the extended call
syntax to keep it in one line:
execfunc = dict(key1 = (func1, ('hello',)))
apply(*execfunc['key1'])
hello
Note that applly is depreciated - you're supposed to use the extended
call syntax instead. This particular use case for apply can't be
handled by the extended call syntax.
Using dictionaries instead of a fixed arg is a trivial change to both
these examples.

If args is a tuple, it should be:

If you want the full generality and use keyword args:

Running autogenerated code in another python instance
Hi all, I've got an application that I'm writing that autogenerates python code which I then execute with exec(). I know that this is not the best way to run things, and I'm not 100% sure as to what I really should do. I've had a look through Programming Python and the Python Cookbook, which have given me ideas, but nothing has gelled yet, so I thought I'd put the question to the community. But first, let me be a little more detailed in what I want to do: I have a python module (called pyvisi, but you don't need to know that) which attempts to simplify the writing of scripts for high performance computing visualisation applications. What it does is provides a layer between the user and the actual renderer backend that is actually going to process the code. Effectively all my app does is to autogenerate the code the user would have to write were they savvy with the python interface to vtk (the visualisation toolkit). This reduces the effort on the part of the user quite a lot. What I have currently is my python module generating the equivalent vtk-python code and then executing this in an exec(). This is not nice (and potentially very slow), especially if one has to share around data, so what I want to do is have a separate python process or thread which just sits there accepting the autogenerated text strings as if the user were writing them directly at the python prompt (or equivalent), and returning any error messages generated. Also, I want to be able to share data between the two processes/threads so that one doesn't have to turn numerical data into a string which is then turned back into numerical data inside the exec() call (ugly, I know, but it works). Maybe a picture will help as well (time going down the page): Main Proc(1) | | Renderer(2) | | | -- Data(3) -- | | | | more commands| | --- | | | | even more cmds | | --- | | | | render finished | | shut down Rndrr | | --- | | | main proc continues or finishes (1) the main process where the python code destined for the backend is generated (2) the secondary process which accepts and runs the code it receives (3) data to visualised; shared between the two processes Ok, hopefully you get what I want to do now... So, what is the best way to do this? Threads share memory, so this is handy to share the data around, however, how does one send arbitrary commands to be processed by a thread? One way to do this would be to use pipes, but this means that I can't share the data around as easily. I've also seen the Pyro project as a possibility, but I would like to keep this as core python as possible. Any help or advice would be really (really!) appreciated.

Lee) writes: Closing off this particular one would make it harder to get benefit of non-C implementations of Python, so it has been judged not worth it. I think I agree with that judgement. The right fix is PEP 343. I am sure you are right. However, PEP 343 will not change the existing body of Python source code. Nor will it, alone, change the existing body of Python programmers who are writing code which does not close files. It might be possible to recompile existing code (unchanged) to capture most typical cpython use cases, I think... E.g., I can imagine a family of command line options based on hooking import on startup and passing option info to the selected and hooked import module, which module would do extra things at the AST stage of compiling and executing modules during import, to accomplish various things. (I did a little proof of concept a while back, see http://mail.python.org/pipermail/python-list/2005-August/296594.html that gives me the feeling I could do this kind of thing). E.g., for the purposes of guaranteeing close() on files opened in typical cpython one-liners or single-suiters) like e.g. for i, line in enumerate(open(fpath)): print '%04d: %s' %(i, line.rstrip()) I think a custom import could recognize the open call in the AST and extract it and wrap it up in a try/finally AST structure implementing something like the following in the place of the above; __f = open(fpath) # (suitable algorithm for non-colliding __f names is required) try: for i, line in enumerate(__f): print '%04d: %s' %(i, line.rstrip()) finally: __f.close() In this case, the command line info passed to the special import might look like python -with open script.py meaning calls of open in a statement/suite should be recognized and extracted like __f = open(fpath) above, and the try/finally be wrapped around the use of it. I think this would capture a lot of typical usage, but of course I haven't bumped into the gotchas yet, since I haven't implemented it ;-) On a related note, I think one could implement macros of a sort in a similar way. The command line parameter would pass the name of a class which is actually extracted at AST-time, and whose methods and other class variables represent macro definitions to be used in the processing of the rest of the module's AST, before compilation per se. Thus you could implement e.g. in-lining, so that #example.py class inline: def mac(acc, x, y): acc += x*y tot = 0 for i in xrange(10): mac(tot, i*i) Could be run with python -macros inline example.py and get the same identical .pyc as you would with the source #example.py tot = 0 for i in xrange(10): tot += i*i IOW, a copy of the macro body AST is substituted for the macro call AST, with parameter names translated to actual macro call arg names. (Another variant would also permit putting the macros in a separate module, and recognize their import into other modules, and do the right thing instead of just translating the import. Maybe specify the module by python - macromodule inline example.py and then recognize import inline in example.py's AST). Again, I just have a hunch I could make this work (and a number of people here could beat me to it if they were motivated, I'm sure). Also have a hunch I might need some flame shielding. ;-) OTOH, it could be an easy way to experiment with some kinds of language tweaks. The only limitation really is the necessity for the source to look legal enough that an AST is formed and preserves the requisite info. After that, there's no limit to what an AST-munger could do, especially if it is allowed to call arbitrary tools and create auxiliary files such as e.g. .dlls for synthesized imports plugging stuff into the final translated context ;-) (I imagine this is essentially what the various machine code generating optimizers do). IMO the concept of modules and their (optionally specially controlled) translation and use could evolve in may interesting directions. E.g., __import__ could grow keyword parameters too ... Good thing there is a BDFL with a veto, eh? ;-) Should I bother trying to implement this import for with and macros from the pieces I have (plus imp, to do it right) ? BTW, I haven't experimented with command line dependent site.py/sitecustomize.py stuff. Would that be a place to do sessionwise import hooking and could one rewrite sys.argv so the special import command line opts would not be visible to subsequent processing (and the import hook would be in effect)? IWT so, but probably should read site.py again and figure it out, but appreciate any hints on pitfalls ;-) Regards, Bengt Richter -- http://mail.python.org/mailman/listinfo/python-list

Web automation with twill
Hi all, this post is a kind of continuation of my Expanding Python as a macro language Among the replies [EMAIL PROTECTED] directed me to: http://www.idyll.org/~t/www-tools/twill.html (a python tool with a language to script web commands) I applied twill to a problem I had solved by hand clicking 220 times on a button and saving the data sent by the server (it is an asp file). In this case web automation is needed! I need the help of some expert or of the author (Titus Brown). The asp file is (I am Italian!): http://www.scienzemfn.unito.it/job_placement/studenti/Elenco_completo.asp If you open it you see a button with Page Down that must be clicked to get all the data in chunks. I used twill (vers. 0.7.3) in interactive mode: twill-sh -u http://www.scienzemfn.unito.it/job_placement/studenti/Elenco_completo.asp or twill-sh ... and then go webaddress With show you see the the list of the html file representing the 1st chunk (page 1 of 223) With showforms you obtain: Form #1 ## __Name__ __Type___ __ID __Value___ PageNo hidden(None) 1 1 Mv submit(None) Page Down Form #2 ## __Name__ __Type___ __ID __Value___ PageNo hidden(None) 1 None button(None) None 1 Mv submit(None) Page Down Using twill you can access the following page and save it by: fv 1 Mv Page down submit save_html file_name with showforms you obtain: Form #1 ## __Name__ __Type___ __ID __Value___ PageNo hidden(None) 2 1 Mv submit(None) Page Down 2 Mv submit(None) Page Up Form #2 ## __Name__ __Type___ __ID __Value___ PageNo hidden(None) 2 None button(None) None 1 Mv submit(None) Page Down 2 Mv submit(None) Page Up Beeing the second page a further button shows up (Page Up) But now I get lost... I am not able to load the 3rd page... In fact repeating the aforementioned sequence: fv ... + submit the button activated by the submit command is Page Up! Any help? IMHO, twill is great ...expecially if we can make it work outside from its first use (automatic web testing). I must also say that it can be called as a module...

As has already been pointed out, users authenticate to Unix systems with a lot more than passwords. Also, it's not a good idea to make a web page use a system password. Web page passwords tend to be poorly protected. Finally, you can't decrypt a Unix password file password. The algorithm is to encrypt what the user typed (with crypt.crypt) then compare that with the entry in the password file. You pass crypt.crypt the user-entered pasword as the first argument, and the password from the password file as the second, and compare the returned value to the password from the password file. mike -- Mike Meyer [EMAIL PROTECTED] http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information. -- http://mail.python.org/mailman/listinfo/python-list

Re: Spambayes modifications with web services
Thank you for the flippant remarks. Let's just say that I found them to be unproductive. I would like to point out the process was not designed to be automatic and I don't believe made such a statement. I should clarify that my desire was to list each domain that was contained in a spam email, so that the user could then: - check if previously it has been reported as spam, or - open the link in their browser, and - check whether the domain was spam or ham, and then if spam - post it to the web service (Post Spam Site to Web Service). Therefore, thanks, yes, I did think through the consequences of my actions. The line that reads WARNING: DO NOT BUY FROM THIS WEBSITE. THE SPAMMER IS., was tongue in cheek, and it seems to be the line that stirred up the condescending comments. What I should have written was something more along the lines of: WARNING: The website domain has been reported by x users as a website that uses illegal spam email to generate business leads I think that is a perfectly useful and fair statement, which I cannot see damaging legitimate business enterprises. I also think it would be quite useful for consumers to know that the domain name they are about to purchase had previously been misused by spammers, and was quite likely to be blacklisted by spam software.

Re: Python and Lotus Notes
Grzegorz Slusarek wrote:
Hello everyone. I have to get data from Lotus Notes and i curious is it
possible doing it with Python. I heard that Lotus Notes using COM, so
the Python does so maybe it can be done? Anyone have any experiences
doing that?
Ane help will by apreciated
Yes, it's pretty simple. Quick example:
from win32com.client import Dispatch
session = Dispatch('Lotus.NotesSession')
session.Initialize(MY_NOTES_PASSWORD)
db = session.getDatabase(SERVER_NAME, DB_NAME)
...
The LotusScript reference guide is almost completely applicable to
Notes via COM.
It can be useful to define some helper functions to make working with
Notes a bit easier. For example, this is the (very clunky) way to
iterate all documents in a Notes database, without helper code:
view = db.getView('Important Docs')
doc = db.getFirstDocument()
while doc:
do_something_with(doc)
doc = view.getNextDocument(doc)
You probably recognize the pattern from any LotusScript you've written.
(It sure is easy to forget that last line...)
But Python gives you far better control structures, like generators.
It's worthwhile to define a few helper functions like this, in a common
module:
def iterateDocuments(docs):
doc = docs.getFirstDocument()
while doc:
yield doc
doc = docs.getNextDocument(doc)
Then you can write much cleaner code, like this:
for doc in iterateDocuments(view):
do_something_with(doc)
Similarly you can write iterator functions for traversing databases,
ACL entries, etc.
I also find these two defnitions useful:
def get(doc, attr):
return doc.getItemValue(attr)
def get1(doc, attr):
return get(doc, attr)[0]
because it's a lot easier to write:
user_name = get1(user_doc, 'FullName')
than:
user_name = user_doc.getItemValue('FullName')[0]
Note that the attribute-access style that LotusScript allows, e.g.
user_doc.FullName(0) does not work in Python/COM, hence you'll need
getItemValue(), replaceItemValue(), etc.. You could write a wrapper for
the NotesDocument class that would give you attributes like this.
Personally, I find that to be more trouble than it's worth, but your
needs be very different.
Last warning: once you've tried using Python and COM, you'll scream
whenever you have to write LotusScript, and you'll wish like crazy that
Notes/Domino supported Python as a native scripting language. :-)
Jython kind of works, but I never got it happily running for
server-side code, alas.

You should try adding /path/to/sybase to sys.path as well as/rather than putting it in an environment variable. sys.path is what the interpreter uses to find importable modules. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC www.holdenweb.com PyCon TX 2006 www.python.org/pycon/ -- http://mail.python.org/mailman/listinfo/python-list
