python-mode tab completion problem

[test1dellboy3 at yahoo.co.uk]

Hi,

I am exploring python-mode on emacs. When I open foo.py in emacs and
hit C-!, it starts the python interpreter in another window. Next, I
execute -

import rlcompleter, readline
readline.parse_and_bind('tab: complete')

Now I will test the completion by trying to complete sys.v (which could
be sys.version or sys.version_info). It works find when I run the
python interpreter from a terminal, by in python-mode, I get -

import sys
sys.v [tab][enter]
'2.3.4 (#2, Jan  5 2005, 08:24:51) \n[GCC 3.3.5 (Debian 1:3.3.5-5)]'

sys.v [tab][tab][enter]
'2.3.4 (#2, Jan  5 2005, 08:24:51) \n[GCC 3.3.5 (Debian 1:3.3.5-5)]'

sys.v [tab][tab][[tab][enter]

sys.version       sys.version_info
'2.3.4 (#2, Jan  5 2005, 08:24:51) \n[GCC 3.3.5 (Debian 1:3.3.5-5)]'

I see that it is doing the completion, but it doesn't show me the
choices before I hit enter, instead it moves the cursor one tab stop to
the right. Any ideas?

Thanks in advance
