Re: Direct acces to db unify on unix sco
hello, I am not sure whether I have understood you correctly, but if you mean unify as in www.unify.com then it is possible to directly link in the unify libraries statically into python. My experience was that the unify libraries do not like dynamic linking. The process of static linking involves using swig wrappers and I always found SCO to be particularly difficult. The process of wrapping using swig is not straightforward and would need a bit of explanation. If ODBC is a realistic option I would go for it, I suspect it would be easier in the long run. luca72 wrote: > Is it possible or i must use odbc? > > Rergards Luca -- http://mail.python.org/mailman/listinfo/python-list

As I see it, there are two solutions to your problems: - Display your strings differently. It may seem stupid, but there are sometimes situations where it is the best solution. Think about Apple's way of displaying full file path names in menus: they put the file base name first, then the full directory after a separator. If you have a way to do that, your problem is solved. - Don't use a Listbox to display your list, but another widget. A simple Text with no wrap option may be a solution; setting a tag with the option justify=LEFT on your whole text would do the trick. But if your lines of text should be selectable, it may not be the right solution. In this case, another widget you can use is a Canvas. It's a little trickier but can be done. Here is an example: -- from Tkinter import * root = Tk() cnv = Canvas(root, width=150, height=250) cnv.grid(row=0, column=0, sticky='nswe') hscroll = Scrollbar(root, orient=HORIZONTAL, command=cnv.xview) hscroll.grid(row=1, column=0, sticky='we') vscroll = Scrollbar(root, orient=VERTICAL, command=cnv.yview) vscroll.grid(row=0, column=1, sticky='ns') cnv.configure(xscrollcommand=hscroll.set, yscrollcommand=vscroll.set) xMax = 0 y = 0 for i in range(20): lbl = Label(cnv, text='Very, very long item number %s' % i) cnv.create_window(150, y, window=lbl, anchor='ne') y += lbl.winfo_reqheight() xMax = max(xMax, lbl.winfo_reqwidth()) cnv.configure(scrollregion=(150 - xMax, 0, 150, y)) root.mainloop() -- Putting bindings on the Label widgets created in the loop can be used to simulate the behaviour of a Listbox.

The message "TypeError: 'module' object is not callable" means that the
"urlparse" that you are trying to call as a function is a module and is
thus not callable.
The module urlparse contains functions urlparse and urlsplit, among
others. I'm dragging urlsplit into the arena as its name is not the same
as the module name, and it might help you see what is happening. There
are two ways of calling them:
(1)
>>> import urlparse
>>> urlparse.urlparse('http://www.cwi.nl:80/%7Eguido/Python.html')
('http', 'www.cwi.nl:80', '/%7Eguido/Python.html', '', '', '')
>>> urlparse.urlsplit('http://www.cwi.nl:80/%7Eguido/Python.html')
('http', 'www.cwi.nl:80', '/%7Eguido/Python.html', '', '')
>>>
(2)
>>> from urlparse import urlparse, urlsplit
>>> urlparse('http://www.cwi.nl:80/%7Eguido/Python.html')
('http', 'www.cwi.nl:80', '/%7Eguido/Python.html', '', '', '')
>>> urlsplit('http://www.cwi.nl:80/%7Eguido/Python.html')
('http', 'www.cwi.nl:80', '/%7Eguido/Python.html', '', '')
>>>
Method (1) is probably better for you at the moment.
I suggest that you read the Modules section in the tutorial:
http://docs.python.org/tut/node8.html
*and* all the earlier sections if you haven't already.

time conversions [hh:mm:ss.ms <-> sec(.ms)
Hi, I was looking at python & datetime and hoping that it would already have a method/func to translate time formats. I need to translate seconds to hh:mm:ss.ms and vice versa and would like the ability to do some basic arithmetic in these formats. I think that there just has to be a package or module out there that already does this with reasonable speed and accuracy. Sadly, i do indeed need both reasonable speed and accuracy since i will be adding up huge masses of small events (around 10 to 60 ms milliseconds in length) to create cloud like textures for real time audio/video at high sampling rates. i googled for hh:mm:ss.ms + python and didn't find much... best, -kp--- [mac os x w/ python 2.4.1] -- http://mail.python.org/mailman/listinfo/python-list

Strange constructor behaviour (or not?)
Hi, when defining: class A: def __init__(self, l=[]): self.l = l a = A() a.l.append() b = A() print a.l I get the output [] instead of an empty list. I guess it's because the default value in the constructor is constructed once and whenever the constructor is called without l being specified. My work around is: class A: def __init__(self, l=None): if l == None: self.l = [] else: self.l = l Is there a way to take the first definition but force the constructor to create a new empty list every time it is called?

If I remember correctly (and its a while since I did this), you may be able to use win32com/client/makepy.py to generate a .py file from a type library. If you do this then the python wrapper will have methods to forward the calls, so you can inspect it as above. Unfortunately, not all COM objects have to have type libraries, so it isn't always possible to do this and then you have to fall back on reading the documentation for whatever COM object you are using. You can also embed a call to gencache.EnsureModule() into your code to generate the needed wrappers automatically: the output from makepy tells you this. The easy way to run makepy is to run PythonWin and use 'COM makepy utility' from its tool menu. Then all you have to do is figure out which of the type libraries in the system is the relevant one. -- http://mail.python.org/mailman/listinfo/python-list
RE: Get all attributes of a com object
Hello,
you only get information about a COM object when you have a wrapper.
But you are using the dynamic invoke (Dispatch). So try the typelibrary
browser
in Pythonwin or use the generated wrapper with makepy or
gencache.EnsureDispatch.
But dir will give you only the methods and internal classes. The
properties
you get with OBJ._prop_map_get_.keys().

I guess that you have seconds-and-a-fraction in a float eg 3723.456 seconds, which is equivalent to 1 hour, 2 minutes and 3.456 seconds. How do you want that represented? You say hh:mm:ss.ms which could be interpreted as a string "01:02:03.456" -- but this format is not very useful for "basic arithmetic". OTOH a tuple representation like (1, 2, 3.456) can accommodate "arithmetic" of some sort or other more easily -- is that what you had in mind? Next question: exactly what basic arithmetic operations do you want to do in the hour-minute-second format, and why do you want to do them in that format, and not the seconds-only format? > I think that there just has to be a > package > or module out there that already does this with reasonable speed and > accuracy. Get the specification right first. Get the accuracy right second. Then worry about the speed. The "arithmetic" of which you speak can't be so mind-boggling that you can't write it in Python and test it yourself.

Here's quick and dirty implementation, but I wouldn't place any bets on it being fast (or accurate enough for that matter!) #!/bin/env python # vim: set noet sw=4 ts=4: import datetime def secs2time(s): ms = int((s - int(s)) * 100) s = int(s) # Get rid of this line if s will never exceed 86400 while s >= 24*60*60: s -= 24*60*60 h = s / (60*60) s -= h*60*60 m = s / 60 s -= m*60 return datetime.time(h, m, s, ms) def time2secs(d): return d.hour*60*60 + d.minute*60 + d.second + \ (float(d.microsecond) / 100) if __name__ == "__main__": for i in (8.123, 0.0, 5873, 12345.6789): print "%12.6f -> %15s -> %12.6f" % ( i, secs2time(i), time2secs(secs2time(i)) ) assert i == time2secs(secs2time(i)) from timeit import Timer timer = Timer( setup="from __main__ import time2secs, secs2time", stmt="time2secs(secs2time(12345.6789))") count = 100 total = timer.timeit(count) print "Time for %d invocations: %.10fs" % (count, total) print "Time per invocation: %.10fs" % (total / count,) And the output: 8.123000 -> 22:13:20.123000 -> 8.123000 0.00 ->00:00:00 -> 0.00 5873.00 ->01:37:53 -> 5873.00 12345.678900 -> 03:25:45.678900 -> 12345.678900 Time for 100 invocations: 9.3959178925s Time per invocation: 0.093959s Huh ... what d'ya know ... good thing I ain't a betting man!

In fact, if a static wrapper has been built for the object

work, eg:

#
# Make sure a proxy module is built behind-the-scenes

The only thing is that you can't always build a proxy

Add file to zip, or replace file in zip
I have a script which zips up a directory, once it does with that
(before it closes the zip file) I want to replace a file that was added
to the zip, say "Foo.txt".
So I tried this...
[code]
z = zipfile.ZipFile("blah.zip", "w")
# zip the directory
#...
z.writestr("c:\\path\\to\\current\\foo_txt_file\\Foo.txt", "some new
data")
z.close()
All this does is add a new Foo.txt file in the zip alongside the
existing oneany suggestions?

If you take utf-8, decode it to Unicode, then re-encode it as cp1252 you'll possibly get \x94.

I deduce that I am the allegedly kind person. Firstly you have a problem with the "even if" part of "I am getting \x94 and such output when using repr (even if str is giving correct output)". Let txt = "\x93hello\x94". So you print repr(txt) and the result appears as '\x92hello\x94'. That is absolutely correct. It is an unambiguous REPRresentation of the string. In IDLE (or similar) on a Windows box (where the default encoding is cp1252) if you print str(txt) [or merely print txt] the display shows hello preceded/followed by the LEFT/RIGHT DOUBLE QUOTATION MARK (U+201C/U+201D) -- or some other pair of left/right thingies. That is also correct enough. Secondly, I stated nothing such about the XML-file. We were discussing "extracting from content.xml using OOopy's getiterator function". My point was that if you were seeing \x94 anywhere, THE OUTPUT FROM THAT FUNCTION must be encoded as cp1252. Here is the relevant part: == AV>> First I noticed that by extracting from content.xml using OOopy's getiterator function, some \x94 codes were left inside the document.

If you saw \x94 in the repr() output, but it looked "OK" when displayed using str(), then the only reasonable hypotheses are (a) the data was in an 8-bit string, presumably encoded as cp1252 (definitely NOT UTF-8), rather than a Unicode string (b) you displayed it via a file whose encoding was 'cp1252'.

You are getting "these \x94 codes" when you do *WHAT* exactly? I refer you to Martin's unanswered questions: """What is the problem then?

Well, I mailed the content.xml to someone as a text attachment and it was damaged at the other end, whereas sending it as a file resulted in flawless transfer. So I guess there is something not quite UTF-8 in it. However Firefox has no problem opening it either here or at the other persons computer (the undamaged file of course).

Indeed, just load the file into ElementTree. Extending the example you

data = zin.read(x)

doc = ET.fromstring(data)

So, probably yes. If it doesn't have a text attribrute if you iterate
over it using OOopy for example:
o = OOoPy (infile = fname)
c = o.read ('content.xml')

OK, I think I understand what you're talking about. It's ElementTree
API. I have a special generator to process content of elements:
def contents(e):
"""Yield sequence of subelements and text between subelements
in the order as they come"""
if e.text:
yield e.text
for sub_e in e.getchildren():
yield sub_e
if sub_e.tail:
yield sub_e.tail
Example:
>>> doc = ET.fromstring("""weatherin Amsterdamis
>>> great""")
>>> list(contents(doc))
['weather', , 'in Amsterdam', , 'is great']

Awesome PySIG meeting last night
Ten folks attended the monthly Python Special Interest Group meeting, held monthly at the Amoskeag Business Incubator in Manchester. Ben was harassed. Announcements were made. Several Python gotchas were discussed. Paul Koning demonstrated a remarkable reinvention of the TECO (Tape Edit and COrrection system) in Python code. Interesting discussions on using a class definition as a dictionary to invoke single- and double-letter commands, even those not allowed as method names. Why exceptions are exceptional. Using wxPython to create a GUI screen for TECO like the PDP-11 VDT peripherals. The bang-up finale was running pi.tec - an inscrutable TECO macro that calculates Pi one digit at a time - to demonstrate his TECO compliance. Amazing. Regulars noted it ran much faster on Paul's laptop than it used to on a PDP-11, too. Next Month's meeting is May 25th and Ray Cote may demonstrate a recent application he's developed in Python.

best way to determine sequence ordering?
If I want to make a list of four items, e.g. L = ['C', 'A', 'D', 'B'],
and then figure out if a certain element precedes another element, what
would be the best way to do that?
Looking at the built-in list functions, I thought I could do something like:
if L.index('A') < L.index('D'):
# do some stuff
But I didn't know if maybe there was a preferred method for this type of
operation, or perhaps a better function to use to figure out the
ordering. Or even if I wanted to write my own utility function to make
it look cleaner than above, I'd still need to use something like above
in my function, so I wanted to know what might be the 'cleanest' looking
solution.

ANN: Leo 4.4 rc1 released
Leo 4.4 release candidate 1 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 This version fixes a few minor bug reported in 4.4b4 and adds 9 new commands. The open-outline-by-name command supports filename completion. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.4: -- - An Emacs-like mini-buffer: you can now execute any command by typing its long name, with tab completion. - Many new commands, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. You can use Leo without using a mouse. - Flexible key bindings and input modes. You can emulate the operation of Emacs, Vim, or any other editor. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The Completion tab shows possible typing completions. - Autocompletion and calltips. - Dozens of other new features and bug fixes since Leo 4.3.3.

os.startfile() - one or two arguments?
Can any Windows user give a working example of adding a "command verb"
to os.startfile()?
When I try it, it squawks that it takes only one argument.
>>> os.startfile('d:/','explore')
Traceback (most recent call last):
File "", line 1, in ?
TypeError: startfile() takes exactly 1 argument (2 given)
from os module
startfile( path[, operation])
Start a file with its associated application.
When operation is not specified or 'open', this acts like
double-clicking the file in Windows Explorer, or giving the file name
as an argument to the start command from the interactive command shell:
the file is opened with whatever application (if any) its extension is
associated.
When another operation is given, it must be a ``command verb'' that
specifies what should be done with the file. Common verbs documented by
Microsoft are 'print' and 'edit' (to be used on files) as well as
'explore' and 'find' (to be used on directories).

The optional second argument was added in Python 2.5 (currently in alpha).

Thanks for the answers, very helpful.

But I'll probably also use Michael's solution for class editing. Now I just have to figure out how to take in-memory structures and turn them into Python source code. Hmm... that actually leads me back to Michael's solution more, since in that model you are always dealing with source, and if you faithfully reproduce the source then you should more-or-less reproduce the same structures. Hmm... challenging. I guess this is one motivation for languages like Smalltalk to use an image, because they don't have to serialize code as source.

It all depends on what CRT version you link Python with. If you use mingw32 to link Python with msvcr71.dll, nothing would change for pywin32 compared to Python 2.4. OTOH, nothing would change for anybody else, either. If you link Python with msvcrt.dll, you would need to build pywin32 with a version of MFC that also links with msvcrt.dll.

I'm more concerned that it might expose some C++ code (symbols) to other python code but I haven't looked at pywin32's implementation so I can't really tell. If it does, one shouldn't use it with _any_ compiler other than the one used to build pywin32.

No, since even if you kill file Xah Lee, he keeps wasting resources of people who have dedicated equipment to support Usenet. > Complaints to ISPs should be reserved for egregious abuse of the > Usenet infrastructure. I consider this abuse, and since the reports are taken serious atm, it looks like the ISP / USP / hosting provider *agree* with my POV. It's their call anyway. Maybe you like to look away when someone throws garbage on the street, thinking: who cares, it will be cleaned away by the end of the week.

Re: wxPython problem
What I'm wondering is, perhaps it has something to do with the wx.pth file? I can't seem to find anything in the documentation about what the path should be, which file it should be pointing to. Scott -- http://mail.python.org/mailman/listinfo/python-list
Urllib2 / add_password method
I'm working on learning how to use urllib2 to use a proxy server. I've
looked through the postings on this group, and it's been helpful. I
have not, however, found complete documentation on the add_password()
functions. Here's what I've got so far:
#
import urllib2
url = 'http://some.server/form.php'
proxy_url = 'http://202.62.252.3:8080' # A publicly available anonymous
proxy server
proxy_handler = urllib2.ProxyHandler( {'http': proxy_url } )
proxy_auth_handler = urllib2.HTTPBasicAuthHandler()
proxy_auth_handler.add_password('realm', 'host', 'username',
'password')
opener = urllib2.build_opener(proxy_handler, proxy_auth_handler)
urllib2.install_opener(opener)
try:
handler = urllib2.urlopen(url)
except urllib2.URLError:
print "whoops!"
else:
print handler.read()
#===
It works, but I don't really know what I'm doing with the
proxy_auth_handler part. Specifying username and password make sense,
but I haven't found documentation on what 'realm' and 'host' are for.
Shouldn't username & password be sufficient?

Yup, in short: stop Xah, and many people don't have to keep their kill files up to date, or switch to a different usenet client.
