title: Python - IronPython dilemma
body: <p>I'm starting to study Python, and for now I like it very much. But, if you could just answer a few questions for me, which have been troubling me, and I can't find any definite answers to them:</p>
  
  <ol>
  <li><p>What is the relationship between Python's C implementation (main version from python.org) and IronPython, in terms of language compatibility ? Is it the same language, and do I by learning one, will be able to smoothly cross to another, or is it Java to JavaScript ?</p></li>
  <li><p>What is the <em>current</em> status to IronPython's libraries ? How much does it lags behind CPython libraries ? I'm mostly interested in numpy/scipy and f2py. Are they available to IronPython ?</p></li>
  <li><p>What would be the best way to access VB from Python and the other way back (connecting some python libraries to Excel's VBA, to be exact) ?</p></li>
  </ol>
