You are using python.el.  You may have more luck with python-mode.el.

C-u M-x py-shell RET
starts a new dedicated interpreter subshell.  I'm not sure exactly what that means, but it looks like it does much of what you want.  You use C-u once, and on subsequent subshell actions python-mode knows to use the same one from the same .py buffer. 

One caveat, it looks like you can't rename the buffer to something with the name of the originating buffer, because then you break the connection between the .py buffer and the subshell.
Some lisp hacking may be required to teach python-mode to prompt for a better subshell buffer name.
