It's more common to spell that with a try/except. Does pylint complain
if you use this instead?
try:
unicode
except NameError:
unicode = str
Although it would be better to write your code for Python 3, and have
compatibility code at the top for Python 2. That would mean using
'str' everywhere, and then having this at the top:
try:
str = unicode
except NameError:
pass
That way, when you're ready to drop support for Python 2, you simply
delete the compat code and everything works. Otherwise, you have to
maintain messy code indefinitely.
Alternatively, to avoid redefinition at all, you could use your own
name everywhere:
try:
unicode_string = unicode
except NameError:
unicode_string = str
Use something less unwieldy if you prefer, but this avoids any chance
of collision :)
