Example taken from UltiSnips:
./py-code/UltiSnips/compatibility.py
./py-code/UltiSnips/compatibility_py2.py
./py-code/UltiSnips/compatibility_py3.py
Everything else is shared.
Of course
if py2:
print "foo"
else:
print("foo")
will not work, but stdout.write("foo\n") would work for both.
Also you could move the code into modules:
if py 2:
import py2
else:
import py3
There are also some module which can be loaded improving compatibility:
http://pythonhosted.org/six/
However I never used such.
