Hi to all,
I need to run a program from inside python (substantially, algorithmic
batch processing).
I'm on mac osx 10.3.8 with python 2.3 framework and macpython.
Trying to use exec*, I checked references, Brueck & Tanner, and then
grab this code from effbot: program = "python" def run(program, *args):
os.execvp(progr am, (program,) + args)
print "ok"
run("python", "/Users/apple/Desktop/prova.py")
Traceback (most recent call last):
File "<pyshell#5 0>", line 1, in -toplevel-
run("python", "/Users/apple/Desktop/prova.py")
File "<pyshell#4 9>", line 2, in run
os.execvp(progr am, (program,) + args)
File
"/System/Library/Frameworks/Python.framewor k/Versions/2.3/lib/
python2.3/os.py", line 336, in execvp
_execvpe(file, args)
File
"/System/Library/Frameworks/Python.framewor k/Versions/2.3/lib/
python2.3/os.py", line 374, in _execvpe
func(fullname, *argrest)
OSError: [Errno 45] Operation not supported
This OSError seems to be consistend with all exec family. What does it
mean and how to use exec?
I also tried with. os.system. It works if I invoke python, but it fails
(in a way I don't know) when I invoke other programs.
For example:
command = "python /Users/apple/Desktop/test.py" os.system(comma nd)
0
(test.py write a string in a file. It works)
But with lilypond or with latex I have no output (and in fact it
doesn't give 0 as result):
command = "lilypond /Users/apple/Desktop/test.ly" os.system(comma nd)
32512 command = "latex /Users/apple/Desktop/test.tex" os.system(comma nd)
32512
Any help is much appreciated
Thanks a lot

The following code provides for about half of the functionality I

Anyone playing with the CPython interpreter's new command line switch might have
noticed that it only works with top-level modules (i.e. scripts that are
directly on sys.path). If the script is inside a package, the invocation will
fail with a "Module not found" error.
This PEP is aimed at fixing that :)
Cheers,
Nick.

found.
