Excel library with unicode support

[Mike Tammerman]

Hi,

I want to create an Excel file, but I don't to use com or any win32
object. Because, the file should be opened via OpenOffice. I found
pyXLWriter, but it doesn't support unicode or non-ascii characters. Is
there a python library, that is able to create Excel files with unicode
characters.

I think, pyXLWriter is a stopped project.

Thanks,
Mike

execute commands independantly

[Mike Tammerman]

Hi,

I am trying to execute an executable or a pyton script inside my
program. I looked at the subprocess and os module. But all the
functions in these modules blocks my application. What I want to do is
run the subprocess without any concern. I don't care of its return type
or child signals. Just start and let it run independantly.

Thanks,
Mike

Re: execute commands independantly

[Mike Tammerman]

You're right,

I tried subprocess.call and os.spawn* functions. Popen is what I will
be happy with.

Thanks a lot.

Printer List from CUPS

[Mike Tammerman]

Hi,

I want to get the printer list from CUPS. I found some ways using

lpstat -p and
http://localhost:631/printers

but, these ways require some parsing and I am not sure, if the parsing
works all the time. A pythonic way would be very helpful.

Thanks,
Mike

Thanks, a lot, this helped me so much. It was so easy, to compile,
install and use the cupsext module.

stdin and py2exe

[Mike Tammerman]

Hi,

I want create a subprocess using Popen and pipe some input to it.
Although everything works perfectly while executing python in, it
doesn't work if I try with executables made by py2exe.

I think, stdin is invalidated if the program becomes an executable.
Because I get a "Bad file descriptor" exception in subprogram.py. I
will be more than apreciated, if any suggestions occur.

Thanks,
Mike

== main.py ==
from subprocess import *

pInput = Popen('python subprogram.py', stdin=PIPE, shell=True).stdin
# pInput = Popen('subprogram.exe', stdin=PIPE, shell=True).stdin #
doesn't work

pInput.write('Data')
pInput.close()


== subprogram.py ==
import sys

input = sys.stdin.read()  # Throws a bad descriptor exception.
print input

Re: stdin and py2exe

[Mike Tammerman]

Yes, it throws exceptions if I build the exe of the subprogram.py.

So, is it possible to pipe some data to another py2exe'd application
without a console.

Elliptic Curve Library

[Mike Tammerman]

Hi,

I need an elliptic curve library that can be used by python. I googled
but couldn't find a one. I'll appreciate, if you could show me.

I will try to implement an ID-Based Cryptography. I also need bilinear
pairing operations.

Function Serialization

[Mike Tammerman]

I want to serialize a function using its pointer. For example

>>> s = """
... def square(number):
... return number**2
... """
>>> functions = {}
>>> exec s in functions
>>> f = functions['square']
>>> f


Then,
1. Serialize f,
2. Store it into a file a db.

One day later,
3. Retrieve from file or db,
4. Unserialize it
5. Use as it is a normal function, maybe I would set it to an object
with setattr

Any help will be very useful.

Re: Function Serialization

[Mike Tammerman]

Michele, thank you for the suggestion, it works as you mention.

But in my case the function is inside a string and I should exec the
string to get the function. Something like this

>>> fields = {}
>>> s = 'def f(): pass'
>>> exec s in fields
>>> f = fields['f']
>>> f

>>> import shelve
>>> d = shelve.open('test.db')
>>> d['f'] = f
Traceback (most recent call last):
  File "", line 1, in ?
  File "/usr/lib/python2.4/shelve.py", line 129, in __setitem__
p.dump(value)
TypeError: expected string or Unicode object, NoneType found

I am not a pro python developer, so I couldn't understand why it throws
exception. I am a bit confused.

Sincerely,

Mike

Re: Garbage collection with QT

[Mike Tammerman]

Not all leakage problems caused by qt or python. There is a wrapping
layer between Qt and Python provided by SIP. Therefore, SIP may cause
leakages. Also PyQt had a paintCell memory leakage problem several
months ago. If you're using an old snapshot of PyQt or SIP, that would
be a problem. Try using the latest snapshots. Also mention your
versions and problems to the PyKDE mailinglist, it could be more
helpful.

If you want to delete C++ objects in Qt, consider using
QObject.deleteLater() method. IMHO, this won't help.
