title: making python interpreter open in same window
body: <p>Maybe I'm being irrational but I really really hate it when a command opens a new window in emacs.  I'm using emacs on Ubuntu which came with python-mode and when I start an interpreter with C-c ! it pops up in a new window.</p>
  
  <p>What I want is for emacs to switch to a new buffer in the same window.  So far I've tried adding <em>Jython</em>(I set the interpreter to jython) to same-window-buffer-names and even going into python-mode.el and changing switch-to-buffer-other-window calls to switch-to-buffer(which I since changed back).  So far I've gotten no change.</p>
  
  <p>I have emacs 23.1.1 and python-mode 5.1.0</p>
  
  <p>Edit: The actual name of the jython buffer is bracketed by asterisks and I don't know how to let stackoverflow know that they aren't styling information.</p>
