Visual Report Editor
Hello, I plan to make Visual Reporting Editior, a new product for corporate-class systems. Data will be in XML and in my application, designer should be able to make fascinating templates of reports. I will use Python and MSVS 2005 Pro. My question is, which libaries will be useful in my job. I plan to buy Qt and make visual layer of application using Qt. I'm making businessplan soI have to decide which tool will be useful. Is Qt best choice, maybe I should buy something different? Pawel -- http://mail.python.org/mailman/listinfo/python-list

Something like that: >>> x = 12345 >>> def foo(): ... global x ... print x ... noglobal(x) # ??? ... x = 0# now this is local x >>> foo() 12345 >>> print x 12345 -- In pariete - manus et crus cerebrumque -- http://mail.python.org/mailman/listinfo/python-list

Bug in the documentation (?)
Hi, Snake Tamers
According to http://www.python.org/doc/2.4.1/lib/typesseq-strings.html (and
next releases):
"""
The conversion types are:
Conversion Meaning Notes
[...]
x Unsigned hexadecimal (lowercase). (2)
X Unsigned hexadecimal (uppercase). (2)
"""
But actually:
Python 2.4.1 (#1, Apr 10 2005, 22:30:36)
[GCC 3.3.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> '%x' % -123456
'-1e240'
so it is a _signed_ hexadecimal.
However, sometimes it would be convinient to get the unisgned conversion
(especially, since id(..) can return a negative value).
This way is rather clumsy:
>>> '%x' % (id('abcd')+0x1)
'b7b75380'
Do you see any better solution?
p.o.

Paramiko, termios - interactive shell connection.
Hi,
I am coding a small SSH client, I ve got some issues with creating
pseudo terminal on server side, or at least I suppose that's the problem.
That is the 'ps auxf' run on SSH server:
root 4317 0.0 0.3 33744 876 ?Ss 11:36 0:00
/usr/sbin/sshd
*### **4525** is the proper connection done with standard ssh
client *|
root 4525 0.3 1.1 53036 2896 ?Ss 11:37 0:00 \_
sshd: [EMAIL PROTECTED]/0**
root 4532 0.0 0.8 15700 2060 pts/0Ss 11:37 0:00
| \_ -bash
root 4987 0.0 0.4 12596 1024 pts/0R+ 11:38 0:00
| \_ ps auxf
*### ..and 4733 is the connection made with my python script , as
you can see it is not using PTS *
root 4733 0.0 1.0 52940 2676 ?Ss 11:37 0:00 \_
sshd: pgega [priv]
pgega 4741 0.0 0.6 52940 1600 ?S11:37 0:00
| \_ sshd: pgega
root 4745 0.0 0.9 33768 2252 ?Ss 11:37 0:00 \_
sshd: [accepted]
Do you see anything worng with my script ? Here is the source code:

Pawel Gega
