"ssh suse-server 'python -V' > python-version.out" not redirecting

Okay, so I have had this problem on openSUSE, and Debian systems now and I am hoping for a little help. I think it has something to do with Python but I couldn't find a proper Python area here.

I am trying to redirect the output of "ssh suse-server 'python -V'" to a file. It seems that no matter what I try, it always prints to stdout. Here is an example of what I am doing.

Code:

user@suse-envy4t:~> ssh suse-server 'python -V' > python-version.out 
not a terminal
Python 2.7.3
user@suse-envy4t:~> cat python-version.out
user@suse-envy4t:~> ssh suse-server 'python -V' | tee  python-version.out 
not a terminal
Python 2.7.3
user@suse-envy4t:~> cat python-version.out

Now, I realize that I could just log into the box and do this but I have a lot of systems to do this on. I want to to rap this in a forloop and so I can get a list of what version of python all the boxes have on them... not being able to capture the output of "python -V" is really making this a pain. I hope this is something stupid that I am doing wrong but "ssh suse-server 'cat /etc/issue'" can redirect just fine with >, >>, or tee... so I don't know what I am doing wrong.

       showdefault
	      Show default python version number. Deprecated, use pyversions(1)

       showsupported

FILES

       /etc/python/debian_config   is	searched   for	 the   attribute   overwrite-local.    If   set   to   1,   or	True,  existing  files	in
       /usr/lib/pythonX.Y/*-packages are overwritten with symbolic links to the pycentral install area. The default is to abort  the  installation
       of  a  package,	when files already exist. This behaviour may be useful, when python libraries were manually installed into this directory.
       The attribute byte-compile can be set to a comma separated list of the values standard and optimze to indicate how files  should  be  byte-
       compiled.
