[Tutor] invoking system commands from python

[Fulvio Copex]

Hello,
i'm new to this list and to python too.
I'm using active state python 2.3 on win32,
my problem is the following: 
I want learn how to execute system command passing parameters.
for example to copy a file I've tried to write this script:
 
*****************************
import os
os.chdir(''myDirectory")
cmd="copy"
parameters="file1 file1_backup"
myCmd = os.popen(cmd,'w')
myCmd.write(parameters)
exitCode = myCmd.close()
if exitCode:
    print '%s failed, this probably says why:\n%s' % (cmd, myCmd)
******************************
 
the problem is that it doesn't work (the file file1_backup is not created)
and it writes the following line:
copy failed, this probably says why:
<closed file 'copy', mode 'w' at 0x01177660>
have tou any idea?
 
thanks,
cop
