Getting wxPython to work on a Mac
Not sure exactly what I need to do to get wxPython to work on either of my Macs. (One's a notebook running Tiger (OS X 10.4.11), the other a Mac Pro running Leopard (10.5.1.)) I downloaded what should be the latest binary, and it installed without error. So Python comes up as $ python -V Python 2.5.1 $ ls -l /usr/bin/python lrwxr-xr-x 1 root wheel 72 Oct 26 17:59 /usr/bin/python@ -> ../../System/Library/Frameworks/Python.framework/Versions/2.5/bin/python $ I set PYTHONPATH to System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5 The Python interpreter works OK, far as I can tell. wx sort of works, but all the functionality is not there. For example, working through the exercises in "WxPython in Action" by Noel Rappin, I find that while I can create and display a frame, and create an app, stuff like wx.MessageBox() just doesn't work. The same exercises work just fine on a Python 2.5.1 installation on my wife's Windows XP machine. Any help appreciated. (I am obviously both a Python and a Wx beginner. And not much of a Unix expert either. :-) -- http://mail.python.org/mailman/listinfo/python-list

i think fcntl is what i'm after, although i've never done any system

sending bytes to parallel port
hello people. i've been trying to send an 8 byte string to my parallel port under freebsd. the purpose is it to control a relay board. the board simply responds to the output byte coming from the port. eg. 0001 will set pin 1 high and flick the relay open. todate i've attempted this with merely open() on /dev/ppi0 and numpy for the byte array, but i just can't seem to get it working. i know the parallel port works and i know the relay board works (tested it with it's own windows ultility) so it's just my crappy programming keeping me from success. -- http://mail.python.org/mailman/listinfo/python-list

i am still coming across this error it's driving me nuts. usually i can
find what's wrong, but it is becoming an increasingly annoying problem.
i also get the same problem on a windows machine with the same
installed. this time it's nothing to do with the decimal module. help!

it is definately a bug in 2.3 when using the decimal module. i can
reproduce it.
from decimal import Decimal
a = Decimal('0'
and when you attempt to run it you will get "error"
of course i do understand that decimal wasn't part of 2.3, but atleast
now when if anyone gets that terse message they know where to start
looking :)

startfile problems
hello i have a very odd issue with os.startfile() ok basicly my app works perfectly on every single other pc todate. i cannot recreate this issue on any system. so i've already ruled out any obvious coding issues, such as wrong file names etc. this issue only occurs on this one old pc. upon trying to os.startfile() a pdf document (that i create) i get the error - Windows error [erro2]"System cannot find the specified file" however when i go in to the program directory, the file is there, and i can open it. i have ruled out the following: the pdf viewer is working. the path and file name are correct the path and file name do not contain any spaces and what not. it's a windows xp system and i'm using python 2.3 i'm very curious as to what everyone thinks -- http://mail.python.org/mailman/listinfo/python-list

urllib download insanity
ok what i am seeing is impossible.
i DELETED the file from my webserver, uploaded the new one. when my app
logs in it checks the file, if it's changed it downloads it. the
impossible part, is that on my pc is downloading the OLD file i've
deleted! if i download it via IE, i get the new file. SO, my only
conculsion is that urllib is caching it some where. BUT i'm already
calling urlcleanup(), so what else can i do?
here is the code
LastModified = urllib2.urlopen('http://x.x.x.x/library.zip')
LastModified = LastModified.headers['Content-Length']
LocalFile = os.stat('library.zip')
LocalFile = int(LocalFile.st_size)
if LocalFile != int(LastModified):
urllib.urlcleanup()
urllib.urlretrieve('http://x.x.x.x/library.zip','library.zip')
as a test i got someone in the office to login and try it - worked
properly for them. i'm on a different ISP to them however, so my other
idea is that possibly my isp has a transparent proxy setup that urllib
is using, but IE isn't???

awesome it looks like it's working now!
it's a very convenient why of keeping them all up today, now instead of
stuffing around making setup packages i can just run my makeexe.bat file
to create the py2exe files, svn commit -m "new package" and i'm done.
also there's no way for the staff to bugger it up ( well, it's fairly safe)
thanks very very much to everyone who made suggestions, this is what
makes OSS so good - the community input and support.

Re: Py2Exe security
i used to work in a place that did this exact same thing. they attempted to hide passwords in source code. there is an even bigger problem with this then security of it in source - if someone comprimises the password, how are you going to change it quickly? all those systems will have to update their exe. keep in mind they could get it any other number of ways forcing you to change it. it's the same reason it's not a good idea to put static address's in source. -- http://mail.python.org/mailman/listinfo/python-list

hi there, this one is in relation to my py2exe saga. when i compile a package using py2exe i get the error msg below, if i just run the py files it doesn't error, so i assume pysvn is trying to use something thats not being included in the build. only i have no idea where to start looking.

I think you're misusing locale. There is no guarantee that any
specific locale will have properties (like grouping) set to a known
value. Are you trying to format money? Then you need a special class
so that you can say:
d = Dollars(100.01)
print "You have %s in your account" % d
and get
You have $1,000,000.01 in your account.
Serge.
thats exactly what i'm trying to do, only having to do that for all
my outputs is more work then i'd like :/
SUS has added numeric grouping
For some numeric conversions a radix character (`decimal
point') or thousands' grouping character is used. The
actual character used depends on the LC_NUMERIC part of
the locale. The POSIX locale uses `.' as radix character,
and does not have a grouping character. Thus,
printf("%'.2f", 1234567.89);
results in `1234567.89' in the POSIX locale, in
`1234567,89' in the nl_NL locale, and in `1.234.567,89' in
the da_DK locale.
but they hasn't added monetary grouping. I don't think you'll
get monetary grouping anytime soon. Besides as far as I understood
your question, you *always* want grouping, right?
Actually I don't think a cryptic flag is better than an explicit
formatter. What do you think is more clear for a maintainer of your
code?
print "%'.2f" % amount
or
print "%s" % dollars(amount)
why is this a misuse of locale? it's exactly what locale is meant for
isn't it?
I just reacted to your words "select a proper locale" and "how do i get
it to group thousands with a ,". It's just not a good idea to select
a locale and expect the grouping character to be "," or expect
grouping,
see nl_NL locale example above.
Serge.
i'm pretty sure english au uses thousands grouping with ,
i've managers to make this work, however it just isn't cross platform at
all.

Have you tried this::
import locale
locale
locale.setlocale(LC_ALL, '')
locale.format('%.2f', 100, True)
The `True` turns on grouping. Should work cross platform.
