Python subprocess
Hi guys,

I'm learning python and perl and i was trying to run from python a perl script using the subprocess module.
I have an issue that i don't understand regarding this.

I run this code:
Code:
#!/usr/bin/python
import subprocess

p2 = subprocess.Popen(["grep", "print", "first.pl"],stdout=subprocess.PIPE)
output2 = p2.communicate()[0]
print output2

p1 = subprocess.Popen(["perl","first.pl"],stdout=subprocess.PIPE)
output1 = p1.comunicate()[0]
print output1

First part : run grep, works as expected, i can get the ouput and display it.
The second one, when i actually want to run the perl script and get the output throws me an error :
Code:
Traceback (most recent call last):
  File "./test.py", line 9, in ?
    output1 = p1.comunicate()[0]
AttributeError: 'Popen' object has no attribute 'comunicate'

I don't understand why this happens since the code is similar. Can someone enlight me?

Thanks,
Ionut

python-config

PYTHON-CONFIG(1)					      General Commands Manual						  PYTHON-CONFIG(1)

NAME

       python-config - output build options for python C/C++ extensions or embedding

SYNOPSIS

       python-config  [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --extension-suffix ] [ --configdir ] [
       --help ]

DESCRIPTION

       python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically
       (at run time) into the interpreter.

OPTIONS

       --cflags
	      print the C compiler flags.

       --ldflags
	      print the flags that should be passed to the linker.

       --includes
	      similar to --cflags but only with -I options (path to python header files).

       --libs similar to --ldflags but only with -l options (used libraries).

       --prefix
	      prints the prefix (base directory) under which python can be found.

       --exec-prefix
	      print the prefix used for executable program directories (such as bin, sbin, etc).

       --extension-suffix
	      print suffix used for extension modules (including the _d modified for debug builds).

       --configdir
	      prints the path to the configuration directory under which the Makefile, etc. can be found).

       --help print the usage message.

EXAMPLES

       To build the singe-file c program prog against the python library, use

	      gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp

       The same in a makefile:

	      CFLAGS+=$(shell python-config --cflags)
	      LDFLAGS+=$(shell python-config --ldflags)
	      all: progr

       To build a dynamically loadable python module, use

	      gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so
