Python to call commands, e.g. "find , perl scripts , nmap , and others" is this possible?

[Roger Upole]

Try win32pipe.popen.  This works very reliably.

I'm running PythonWin
I tried python from the command line.  The process hangs.
>>> import os
>>> os.popen('dir').readlines()
 (hangs . . .)
IDLE gives the same results as PythonWin:
>>> import os
>>> os.popen('dir').readlines()
Traceback (innermost last):
  File "<pyshell#1>", line 1, in ?
    os.popen('dir').readlines()
OSError: (0, 'Error')
Apparently you are right about Window pipes.  <MSJAB> Not surprising.
Microsoft would probably get rid of the command line completely if not for
its legacy value.  It's hard to control the world when the prolls have
access to a usable command shell. </MSJAB> :-)

 Ken, Are you trying this in IDLE?  I get the same error there.If so, try
starting python from within a dos window andsee if that makes a difference.
Pipes in winxx are somewhatflakey as I understand.

 On NT I get:
>>> mylist = os.popen('dir').readlines()
Traceback (innermost last):
  File "<interactive input>", line 1, in ?
OSError: (0, 'Error')
(same thing with any command)
popen (command[, mode[, bufsize]])
    Open a pipe to or from command. The return value is an open
    file object connected to the pipe, which can be read or written
    depending on whether mode is 'r' (default) or 'w'. The bufsize
    argument has the same meaning as the corresponding argument
    to the built-in open() function. The exit status of the command
    (encoded in the format specified for wait()) is available as the
    return value of the close() method of the file object, except that
    when the exit status is zero (termination without errors), None is
    returned. Availability: Unix, Windows.

Dear list,
I'm new to Python, and I'm sorry if I'm asking about anything that has been
already discussed.
I would like to use Python to call commands, e.g. "find , perl scripts  ,
nmap , and others" is this possible?
I do not need GUI. All I need is to link the out put and work with it. Is
perl or shell scripts my only
answer?
