 <p class=f>Virtually all Python 2 programs will need at least some tweaking to run properly under Python 3. To help with this transition, Python 3 comes with a utility script called <code>2to3</code>, which takes your actual Python 2 source code as input and auto-converts as much as it can to Python 3. <a href=case-study-porting-chardet-to-python-3.html#running2to3>Case study: porting <code>chardet</code> to Python 3</a> describes how to run the <code>2to3</code> script, then shows some things it can&#8217;t fix automatically. This appendix documents what it <em>can</em> fix automatically.

 <p class=f>We&#8217;ve already covered a few special method names elsewhere in this book&nbsp;&mdash;&nbsp;&#8220;magic&#8221; methods that Python invokes when you use certain syntax. Using special methods, your classes can act like sequences, like dictionaries, like functions, like iterators, or even like numbers! This appendix serves both as a reference for the special methods we&#8217;ve seen already and a brief introduction to some of the more esoteric ones.
