Re: Which blog tool
There's actually a very simple way to achieve this. In your blogger settings you can specify an email address to which you can email blog posts. Using this, you can simply mail the content from within your python script. I think that's probably the most hassle-free way.

Re: DOS problem (simple fix??)
I tend to run "cmd" and "cd" to the directory of the script, then run it. This way, the window doesn't close, and I can read any errors that occur without interruption. Optionally, you can run "cmd" and simply drag the script you want to run into the window. That pastes its path (in quotes) into the command line, and you can just hit enter. I wouldn't recommend this, though, because the cwd wouldn't be that of the script, and it could cause instability for some apps that use relative paths.

shutil.move has a mind of its own
Hello, I'm writing an application in my pastime that moves files around to achieve various ends -- the specifics aren't particularly important. The shutil module was chosen as the means simply because that is what google and chm searches returned most often. My problem has to do with shutil.move actually putting the files where I ask it to. Citing code wouldn't serve any purpose, because I am using the function in the most straight forward manner, ex: shutil.move( "C:\omg.txt" , "C:\folder\subdir" ) In my script, rather than a file being moved to the desired location, it is, rather, moved to the current working directory (in this case, my desktop -- without any exceptions, mind you). As it happens, the desired locations are system folders (running windows xp, the folders are as follows: C:\WINDOWS, C:\WINDOWS\SYSTEM, C:\WINDOWS\SYSTEM32). To see if this factor was causing the problem, I tried it using the interpreter, and found it to be flawless. My question boils down to this: What factors could possibly cause shutil.move to fail to move a file to the desired location, choosing instead to place it in the cwd (without raising any exceptions)? Thank you for your time, Daniel Bickett P.S. I know I said I didn't need to post code, but I will anyway.

More people need to work on improving the YAML spec and > implementing better YAML parsers. We've got too many XML parsers as it is. However, one of the main reasons that XML is so successful is because it's roots are shared by (or, perhaps, in) a markup language that a vast majority of the Internet community knows: HTML. In it's most basic form, I don't care what anyone says, XML is VERY straight forward. Throughout the entire concept of XML (again, in its most basic form) the idea of opening and closing tags (with the exception of the standalone tags, however still very simple) is constant, for all different data types. In my (brief) experience with YAML, it seemed like there were several different ways of doing things, and I saw this as one of it's failures (since we're all comparing it to XML). However I maintain, in spite of all of that, that it can easily boil down to the fact that, for someone who knows the most minuscule amount of HTML (a very easy thing to do, not to mention most people have a tiny bit of experience to boot), the transition to XML is painless. YAML, however, is a brand new format with brand new semantics. As for the human read-and-write-ability, I don't know about you, but I have no trouble whatsoever reading and writing XML. But alas, I don't need to. Long live elementtree (once again) :-) Daniel Bickett -- http://mail.python.org/mailman/listinfo/python-list

Help! Host is reluctant to install Python
I've been trying to convince my host to install python/mod_python on his server for a while now, however there are a number of reasons he is reluctant to do so, which I will outline here: 1. His major reason is optimization. He uses Zend's optimization of PHP as an example, and he has stated that python is rather resource consuming. 2. Another one of his points is that he is unexperienced in installing python, and he would not know how to do it securely. By 'securely', I'm assuming he means disallowing a malicious (or ignorant) user from harming the server And, in light of point #1, I suggested that if there wasn't any optimization immediately available, he could just enable it for my account (thus lessening potential resource consumption at any given time), to which he retorted "Do /you/ know how to do that?", and I must say, he has me cornered ;-) I have no experience with this sort of thing, so I'm asking a little assistance in the direction of any documents or websites (or what have you) I could show him in order to answer some of these questions, or perhaps even some unspoken ones -- anything worth noting.

Possible additions to the standard library? (WAS: About standard library improvement)
I was reading the thread by Frank Bello[1] about his offered addition
to the xmlrpclib module, and it reminded me of a few methods I had
made in the past that I considered worthy of being a part of the
standard library.
Rather than reiterate his question of how one gets one's patch into
the standard library -- as I can simply read the answers from his
thread -- I am posting here asking the opinion of the Python community
as to whether *you* consider these worthy of standard library
implementation.
The first one is a function I made for the _winreg module[2]. The
commentary, I think, explains what it does and why it had to be
written very clearly, so I'll just copy and paste it:[3]
|def DeleteKeyAll( key , subKey ):
|"""
|Since DeleteKey() can't remove keys that contain subkeys, this serves
|to iterate through a key and delete every single subkey, and then the
|key itself.
|
|Note: This function assumes that _winreg has been imported using:
|from _winreg import *
| It can be easily converted by simply prepending all of the
| applicable statements with `_winreg.' if you have imported
| it otherwise.
|"""
|# try to open the specified key
|try:
|handle = OpenKey( key , subKey )
|except EnvironmentError:
|return False
|# now, iterate through the subkeys and remove
|# each of them (recursively)
|while True:
|nextKey = QueryInfoKey( handle )[0]
|if not nextKey:
|# if there aren't any more subkeys, delete the key at hand
|try:
|DeleteKey( key , subKey )
|return True
|except EnvironmentError:
|break
|else:
|# otherwise, recursively delete the subkeys
|DeleteKeyAll( key , subKey + "\\" + EnumKey( handle , 0 ) )
These next two are methods that I've applied to my own version of the
string object from time to time:
|class newstring( str ):
|def setreplace( self , set ):
|"""
|Do multiple replaces at once, using dictionary `set' as a legend,
|where each instance of each key is to be replaced with that key's
|value.
|"""
|if type( set ) == dict:
|result = self.__str__()
|for key, value in set.iteritems():
|if type( key ) == str and type( key ) == str:
|result = result.replace( key , value )
|else:
|raise TypeError, "All items of parameter set must
be strings"
|return result
|else:
|raise TypeError, "Parameter set must be a dictionary"
|
|def reverse( self ):
|"""
|Return a reversed copy of string.
|"""
|string = [ x for x in self.__str__() ]
|string.reverse()
|return ''.join( string )
In action:
>>> string = newstring("foo bar")
>>> string.reverse()
'rab oof'
>>> string.setreplace( { 'f' : 'b' , 'a' : 'o' } )
'boo bor'
I actually went on to write a method that reversed an integer
(inspired by an SAT question -- I had time to kill) using the
newstring's reverse() method, but it's hard enough justifying having a
string reverse method (though not impossible,) let alone an integer
reverse method, so I left that one on my hard drive :)
One more thing worth noting is that I'm not educated in the ways of
standard library etiquette, so I was more or less going out on the
limb doing type-checking in setreplace(). For all I know that's some
sort of paradox and you're supposed to let the user feel the pain, but
I did what I felt was right at the time.
This is basically all about commentary and criticism, and your opinion
of whether or not these deserve to be added to the library (or rather,
added as a patch, I presume). Thank you all for your time :)
P.S.:
I have included all of the methods in this post for the sake of
accessibility, and i have preceded all of the code with `|' because I
am unaware of the status of google's whitespace problem. If you want
to more easily copy and paste this code, I have posted it on nopaste:

NOTES:

python, but I'm assuming it's C, so I don't know how possible it is to
add pure python to it...

Re: returning True, False or None
I'm seeing a consistent problem in most of these approaches. Verbalized, the logic of the OP's original code reads as such: If True is in the list *at all*, return True. Otherwise, if False is in the list *at all*, return False. Otherwise, return None. So if we used Alex Martelli's code: > for val in lst: >if val is not None: >return val > return None and the list was: [ False , False , True , None ] False would be returned upon inspection of the first index, even though True was in fact in the list. The same is true of the code of Jeremy Bowers, Steve Juranich, and Jeff Shannon. As for Raymond Hettinger, I can't even be sure ;) The original OP's code, on the other hand, inadvertently searches through the list twice where once would have sufficed, causing a needless performance pitfall. The following applies the OP's initial logic while only iterating once: >>> def boolhunt( items ): falseExists = False for item in items: if item is True: return True elif item is False and not falseExists: falseExists = True if falseExists: return False >>> l1 = [ True , None , None , False ] >>> l2 = [ None , False , False , None ] >>> l3 = [ False , True , True , True ] >>> boolhunt( l1 ) True >>> boolhunt( l2 ) False >>> boolhunt( l3 ) True It isn't elegant or clever, but it gets the job done :) -- Daniel Bickett dbickett at gmail.com http://heureusement.org/ -- http://mail.python.org/mailman/listinfo/python-list

Yet Another Python Web Programming Question
This post started as an incredibly long winded essay, but halfway through I decided that was a terribly bad idea, so I've trimmed it down dramatically, and put it in the third person (for humor's sake). Once upon a time a boy named Hypothetical programmed in PHP and made many a web application. It would be a long while before he would find Python, and since that time he would have no desire to ever touch PHP again. He would, however, be compelled to write a web application again, but in Python now, of course. He would read the documentation of Nevow, Zope, and Quixote, and would find none of them to his liking because: * They had a learning curve, and he was not at all interested, being eager to fulfill his new idea for the web app. It was his opinion that web programming should feel no different from desktop programming. * They required installation (as opposed to, simply, the placement of modules), whereas the only pythonic freedom he had on his hosting was a folder in his /home/ dir that was in the python system path. * See the first point, over and over again. All he really wanted was something that managed input (i.e. get, post) and output (i.e. headers: "Content-type:"), and he would be satisfied, because he wasn't an extravagant programmer even when he used PHP. Python using CGI, for example, was enough for him until he started getting 500 errors that he wasn't sure how to fix. He is also interested in some opinions on the best/most carefree way of interfacing with MySQL databases.

If you simply wanted to get rid of quotes entirely, you could use:

However, since you only want the beginning and ending quotes removed:
>>> string = "\"If thou wert my fool, nuncle...\""
>>> print string
"If thou wert my fool, nuncle..."
>>> if string.startswith("\""): string = string[1:]
>>> print string

Skinnable/Stylable windows in wxPython?
I'm very near finishing a medium to large scale application, so I'm getting a head start on the GUI side of things. Part of the concept is to give as much attention to presentation as functionality, and something I really wanted to do was transcend the basic window and style it to an extent, To be honest, the wxPopupWindow was basically what I was looking for, but it isn't available on Mac, eliminating that possibility. wxShapedWindow would have sufficed, but it uses a more recent version wxPython that I've chosen not to install for various dependency issues, so I really can't use that. I've combed through the demo countless times, but I really can't find any answers. So, the question: what is the best way (or is there one, rather) to achieve an end comparable to skinning my wx windows? Thanks for your help, Daniel Bickett -- http://mail.python.org/mailman/listinfo/python-list

Daniel Bickett -- http://mail.python.org/mailman/listinfo/python-list
Re: Skinnable/Stylable windows in wxPython?
Solution found!
For the future reference of anyone searching:
The wxPopupWindow can easily be achieved by creating a wxMiniFrame
with absolutely no styles ('0', explicitly). The features of the
wxPopupWindow in the wxPython demo don't come with it, they were
manually added in the demo code, so simply adapting the code should
suffice.
Even as I was typing this message, I realized that this was probably
exactly what wxPopupWindow was, and suddenly this clicked because I
remembered seeing in the wxWindows help files that all of the styles
for wxMiniFrame only worked on Windows and Motif, and it made a point
to note that they didn't work on GTK. So I tried a snippet of code[1]
on my Mac (until then I had been working on a windows box) and, to my
surprise, it worked perfectly.
This raises some questions for me, like why, if the wxPython package
is going to have the wxPopupWindow feature, they don't simply inherit
wxMiniFrame like I did (quite literally, it looks /exactly/ the same
as a wxPopupWindow). Not only would this make it more multi-platform
(I have no access to a GTK machine so I don't know if this works.
Could someone please check?), but it would be more useful, considering
the fact that it is in fact a frame, and wouldn't have the problems
that M.E.Farmer outlined above regarding controls on wxPopupWindows.
Regardless, I'm happy that I've uncovered the answer, and I hope this
helps someone else in the same situation :)

NOTES:
[1] from wxPython.wx import wxMiniFrame, wxPySimpleApp
app = wxPySimpleApp()
frame = wxMiniFrame( None , -1 , '' , size = ( 300 , 150 ) , style = 0 )

No, I think that was a slip on my part when copying the code from one screen to the next :) > One odd thing > though: the Windows version doesn't react to clicking or dragging the > mouse, which seems to be the expected behavior. I noted in my second post that the functionality of the window (clicking and dragging et al) was, even in the wxPopupWindow demo, implemented by using the EVT macros. Copied from the demo, the code is as follows: def OnMouseLeftDown(self, evt): self.ldPos = evt.GetEventObject().ClientToScreen(evt.GetPosition()) self.wPos = self.GetPosition() self.CaptureMouse() def OnMouseMotion(self, evt): if evt.Dragging() and evt.LeftIsDown(): dPos = evt.GetEventObject().ClientToScreen(evt.GetPosition()) nPos = (self.wPos.x + (dPos.x - self.ldPos.x), self.wPos.y + (dPos.y - self.ldPos.y)) self.Move(nPos) def OnMouseLeftUp(self, evt): self.ReleaseMouse() def OnRightUp(self, evt): self.Show(False) self.Destroy() > The GTK version can be > moved by dragging the mouse; even just clicking the mouse moves the > window somewhat down and to the left. That's interesting... I wonder if using those methods would conflict at all. Also, while I'm on that note, when double clicking on the resulting window (after binding those events), double click causes a non-fatal, yet annoying, traceback saying that "the mouse could not be released because it has not yet been caught blah blah", so I just wrapped the contents of OnMouseLeftUp in a try..except..pass.

Re: IDLE problem :-(
This is less of a bug and more of an inconvenience, on your part. It happens because IDLE has a tailored shell allowing your cursor to venture beyond the prompt, and across the text that the window consists of (much like a loaded file in a text editor) Thus, the beginning of each line is not limited to the beginning of the prompt, and 'home' sends you beyond it. The only 'work around', so to speak, I can think to recommend is simply using a different shell for your purposes, i.e. python.exe (on windows).

Re: need some help with threading module...
I found your object-oriented approach, while admirable, a little muddled. So rather than modify your code, I simply took the paragraph you wrote describing the scenario and wrote my own.[1] Instead of having the Controller query the Subject (not exactly plausible), I had it wait for a signal (threading.Event) as set by the Subject. You could also have it query a queue, as that is a generally accepted and thread-safe object to use, but for this purpose I chose an event and a global variable. (I'm aware that some would look down on this, but I didn't see a problem, as it was only modified by one thread amd printed by the other.)

Re: Tricks to install/run Python on Windows ?
While I don't have any solutions for your problems outlined above, you certainly don't need to limit yourself to the "tools" you've been exposed to (nor should you make a generalization based on them). If PythonWin is giving you that much trouble, you could optionally use a different editor. I use DrPython[1] from time to time. Also, when you say that you had to reinstall your "machine", surely you didn't mean your operating system? I don't think it would be too difficult to find a list of registry keys that Python uses, (or, indeed, inquiring towards the values of those that 2.4 uses and manually adding them) but I seriously doubt it involves any that your system's stability balances on.

Event-Driven Woes: making wxPython and Twisted work together
Hello, I am writing an application using two event-driven libraries: wxPython, and twisted. The first problem I encountered in the program is the confliction between the two all-consuming methods of the two libraries: app.MainLoop, and reactor.run. Additionally, the fact that wxPython was to receive requests from the twisted framework as well as the end user seemed to be simply asking for trouble. My initial solution was, naturally, the wxPython support inside of the twisted framework. However, it has been documented by the author that the support is unstable at this time, and should not be used in full-scale applications. I instinctively turned to threading, however on top of the trouble that this has caused on its own, it has repeatedly been suggested by the twisted IRC channel not to do this. After much dwelling on the issue, I have resolved to turn to c.l.py, to see if anyone had a solution to this problem. Any help would be very much appreciated, Daniel Bickett -- http://mail.python.org/mailman/listinfo/python-list
