Passing arguments to a command line from a python script

[=?iso-8859-1?q?Luis_M._Gonz=E1lez?=]

Please forgive me if what I'm asking is non sense...

I created a little program to authomate the creation of the "setup.py"
script for py2exe.
It simply prompts for the main executable script name and then creates
setup.py, as follows:

# this is "makesetup.py"

nombre = raw_input('File name?: ')

f = open('setup.py', 'w')

f.write('''
from distutils.core import setup
import py2exe

setup( name = "%s",
windows = ["%s.pyw"],
data_files = [ (".", ["%s.rsrc.py"]) ]
)
''' %(nombre, nombre, nombre))

f.close()

# end of script

What I want now is execute the script I just created.
As far as I know, the only way to execute the script is from a command
line and typing "setup.py py2exe".

Can I do this authomatically right from my program?
If so, how?

Any hint would be highly appreciated...
regards,
Luis

A few ways:
- os.system("commandline"). Simplest way, but you don't have much control,
and it blocks until the process finishes.
- os.popen[234]? or the functions in the popen2 module
- the subprocess module - the most complete way, but simple enough for
most cases.

I'm sorry, but still I can't figure out this...
Would you please show me a sample usage of os.system or os.popen for
passing arguments to the command line?
In this case, I should pass to the command line "setuppy py2exe".

Thanks!
Luis

This implies that `os.system("setuppy py2exe")` should do what you
want.

It works!
Thank you, this is just what I wanted.

You'll get better error checking if instead you do::

>>> import subprocess
>>> subprocess.call(['setup.py', 'py2exe'])

Actually, you probably should really be doing::

>>> subprocess.call(['python', 'setup.py', 'py2exe'])

so that you don't have to assume the OS knows how to run a .py file.
