Unable to store "python --version" to a shell variable

Hi All,
I need to get the version of python installed and store it in a variable for later use. Whereas it is printing on the console instead of storing to variable. I am able to store output of ls command in a variable. Please check the below code :

Code:

root@myhost:/volumes/srini# cat python_version.sh 
python_version=python --version
echo "****"
echo $python_version
echo "****"
ls_output=ls -l python*
echo "****"
echo $ls_output
echo "****"

Please check the output of the code :

Code:

root@myhost:/volumes/srini# ./python_version.sh 
Python 2.6.8
****

****
****
-rwxr-xr-x 1 root root 147 May 26 09:35 python_version.sh
****

Please note, its able to store output of ls command in a variable, but not of python --version. Its directly displaying in console.

Regards,
Srinivasan

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.
