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

       --help Produce a help summary.  It might be more helpful than this manual page.

AUTHOR

       The python-coverage command is a one-line Python script which calls the coverage.py Python module to do all the work.  The module was rigi-
       nally developed by Gareth Rees, and is now developed by Ned Batchelder.	The module's home page is
       http://www.nedbatchelder.com/code/modules/coverage.html.

       This manual page was cobbled together by Lars Wirzenius for Debian, by copy-pasting from the help texts from the module.
