Hi:
Do you mean the following code?
#!/usr/bin/python
# OS: Ubuntu
import subprocess
fileName = open ('final.txt', 'a')
fileName.write ('%s %s %s \n' % (12,25,9))
fileName.flush() # add
fileName.close() # add
desLrr = subprocess.Popen('ls -a >> final.txt', shell=True) # change to "ls

I was just looking at Debian's benchmarks. It seems LuaJIT is now (on
median) beating Intel Fortran!
C (gcc) is running the benchmarks faster by less than a factor of two.
Consider that Lua is a dynamically typed scripting language very
similar to Python.

If I change "'echo "hello">> final.txt" to "ls -a >> final.txt" and add
fileName.close() before subprocess.
The result is still like:
12 25 9
85 25 12
# list of files
.
How can I put the list before the number list 85 25 12?
Thank you.

if I use 'print' to print the whole list, 'print' will add newline

Hi Richard!
I have downloaded iptcinfo and placed it in python27\Lib\site-packages
\iptcinfo
I guessed that was the right place, because that is where PIL ended
up, but that had a fancy installer with it.
You did place it in the right path, but the "fancy installer" does one
more thing, it

Hello together,
python: 2.5.1

I'm using pickle.dump and pickle.load with data that is created in a wrapped
(boost.python) piece of C++ code. pickle.dump works fine. pickle.load creates

[...]
data = pickle.load(input)
