Let’s instead drop six entirely and inline the text_type definition for the single place where it’s used.

Thanks but that’s what I meant. text_type is different in Python 2 and Python 3.

You mean like:

import sys

PY2 = sys.version_info[0] == 2

def text_type(value):
    return unicode(value) if PY2 else str(value)

[jonashaag]

Yep

Thank you!
