sys.version_info gives you a tuple, which is way more convenient for comparisons than sys.hexversion:

    if sys.version_info >= (3,):
        ...  # Python 3.X code

Or you could check whether str is bytes:

    if str is bytes:
        ...  # Python 2.X code

That is why I used sys.hexversion. Since there are 3 paths, has real bytes, fake str bytes, and no bytes.

[jwilk]

bytes exists since Python 2.6. Do you really need to support anything older?

Maybe not, but the incremental work was less than making a single codebase work for both 2 and 3. It's code that runs on openwrt, so forcing my ideas on the users is painful for them...they would have to build a whole new image.
