I see no reason to introduce clutter like this at this point in time -
code needing to run in both Py 2 nd 3, if not using something like
"six" could do:
compat.py
try:
unicode
except NameError:
unicode = basestring = str
elsewhere:
from compat import unicode, basestring
Or rather:
try:
unicode
else:
str = basestring = unicode
and
from compat import str
# therefore having Python3 valid and clear code from here.
