More precisely there is the tool "2to3" which is shipped with py3. It gets the syntactic changes out of the way, and also copes with renamed imports and some straightforward behavioural changes (lists turned into iterators, etc.) By default it shows a diff, with -i it applies the changes. I haven't seen its output to be actively wrong, it's generally quite a good one. In some cases it's overcautious and overcomplicates the syntax unnecessarily, and in some cases when you want to make your code work with both py2 and 3 you have to be more creative, but it's a general first step for a port. However, what the tool can't sort out for you is to properly sort out byte arrays vs. strings in your code; python2 has mixed those all over the place, resulting in the ever-enjoyable UnicodeDecodeErrors that happen in only some circumstances/locales. py3 is strict with that, which takes some effort in porting, but results in much more stable code.
