I've tried changing data.startswith('-----') to data.startswith(b'-----'), but got another error:

The current code works with Python 2.7.13. Not with 2.7.6, or with Python 3.
The README.md shows how to use Docker, or pyenv to get 2.7.13 (or any other Python version).

Getting it working with Python 3 is an important enhancement request.

README.md states It won't work with lower Python version., so I've used my system's default 3.4. But OK, I've changed it to pip2.7 install and it works fine now. Thank you.

I agree py3 compatibility is imporant feature request! :)

What.

Why does the setup.py list the classifiers:

        'Programming Language :: Python :: 3',
        'Programming Language :: Python :: 3.3',
        'Programming Language :: Python :: 3.4',
        'Programming Language :: Python :: 3.5',

If none of that is actually true?

It is the easiest way to quickly check which version of python something is meant for. 😞

Also setuptools allows you to mark which versions of python are compatible...
