Hi all,

With the end-of-life of Python 2 upon us, I wondered about cleaning up code that has (had!) to support both Python 2 and Python 3. Some of it is easy (e.g. look for any references to the ?six? library), some of it is relatively easy (e.g. super(Foobar, self) ) and? actually, there could be quite a few things to tidy up. 

I?m wondering if there is a script out there to quickly introspect a codebase and flag up any legacy code? I?ve tried googling but drew up a blank. Any suggestions welcome!

Richard

Hi Richard,

One trick that I have used is to use os.walk to find all of the python files and then tried parsing them with ast - this at least throws an error for the files that are completely broken for python 3. Another is to use the python 3 version pylint on the files/project this finds more but in many cases results in a lot more noise.

We've had good luck using https://github.com/asottile/pyupgrade as a
pre-commit hook (see https://pre-commit.com/ ? highly recommended).

We were already using Python 3, but it's helped us deal with some of the
3.n -> 3.n+1 upgrades.

That might do the trick - I?ll try it out. Mucho thanks!

There's been loose talk of adding "minus2" fixers to 2to3, but I don't know
whether there's been any concrete progress.

At least most refactorings will be taking place on a code base that already
runs on Python 3, so tests (where they exist) can ensure that such
automated refactorings would do relatively little damage.

Kind regards,
Steve Holden
