[Tutor] Python 2.2... os.exec catch stdout
*Hello. I am relegated to running python 2.2; so I do not have access to subprocess. In my script; at one point, I need to run a program; interact with the program; exit the program; and parse the output printed to stdout. This would be simple; if I did not need to interact with my sub-program. I currently have.. import os program = "vim" arguments = ["myFile"] pid = os.fork() if not pid: os.execvp(program, (program,) + tuple(arguments)) os.wait()[0] This works fine; lets me interact with "vim" fine; and return to the python script when I am done; but I do not seem to be able to execute read stdout; and all examples I have found on the net do not allow me to interact with the called program. Any pokes int he right direction? Thanks, Chris * ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Best Python Editor
for note; full tag completion and tag support can be used in vim via omnicompletion and taglists. Full class support/heiarchy + printing of the docscrint as you ctrl-n through each completion in the preview window. Extremly useful when using someone else's library or for remembering what to pass in; and mostly native to vim. I have never used a debugger (i usually use break points and prints, with a quick e to run and examine output); but I would assume it's there if you want it as I have seen GDB integration (as well as any VCS you would want, which suprises me that has not come up yet.) It just comes down to whether you want ot make the learning investment or not. After using it for awhile; your workflow just; well; flows. This to me is the biggest complement to an editor.

[Tutor] "Snack" python-newt version incompatibilities.. (anaconda kickstart)
Hello all.
I'm working on a CentOS 5.2 kickstart interface; and have been happily using
%pre --interpreter /usr/bin/python
to do my management for awhile now with the snack module. My problem
comes in when I am attempting to use the snack.EntryWindow function;
and setting default values.
The simplified version of my code is below...
(default1,default2,default3,default4)=('1','2','3','4')
#These are all of my prompts.
prompts = [('Static1',default1), ('Static2',
default2),('Static3',default3),('Static4',default4)]
ok, params = snack.EntryWindow(screen, "This is my title",
"This is my text at top of box",
prompts,
help = "")
On my desktop, I have...
$>python -V
Python 2.5.2
The defualt python in CentOS5.2 is..
$>python -V
Python 2.4.3
The snack window behaves as expected on my desktop (default values all
populate and change values as I want/expect), but when I try and run
on the 2.4 python, i get the following(output cleaned up a little bit
as it splays the entire window)...
File "/usr/lib/python2.4/site-packages/snack.py", line 796, in EntryWindow
sg.setField(e, 1, count, anchorLeft = 1)
File "/usr/lib/python2.4/site-packages/snack.py", line 388, in setField
(what.__dict__.has_key('g')):
AttributeError: 'str' object has no attribute '__dict__' selects
With some googling, I managed to find references to a bug in the
python snack module that was fixed, but I was unable to find a working
format of the "prompts" variable to work in my Python 2.4.3.
I tried the above code, as well the suggestion from the link below of
prompts = [Entry(20, 'ham'), Entry(20, 'egg', hidden=True)]
But to no avail. Any help would be greatly appreciated...
