2008/12/25 Dennis van Oosterhout <de.slotenzwem...@gmail.com>:Hello Arno, thanks for the explanation! I have one more question: on the python site it says it's better to replace the system commands by subprocess and Popen. Now I searched for some good example for my specific case (as I have no idea how it should work and I don't get it any clearer by reading http://docs.python.org/3.0/library/subprocess.html#module-subprocess) and I found this:import subprocess def clear(): subProcess.Popen('clear')

say it otherwise: the program isn't platform independant?
what you are doing is executing a shell command. look at it this way: you open a DOS shell: start/run/command there you enter the python interpreter by typing python (i think...) now you can execute python commands but if you want to execute DOS commands again, you need to find a way to get "out" of python and back in to DOS this is what happens...so, "leaving" python brings you back into windows if you are on a windows system thus you can't execute *nix commands and to answer your question, those commands
are system commands and so they are very system dependent ;)
