If we use 3.0.10 <= SWIG < 4.0.0 in release process and want to
generate code for Python 3:

  SWIG_PY_OPTS="-python -py3 -nofastunpack -modern"

If we use SWIG >= 4.0.0 and want to generate code for Python 3:
  
  SWIG_PY_OPTS="-python -py3 -nofastunpack"

If we want to generate code for Python 2, use 1.3.24 <= SWIG < 4.0.0 and

  SWIG_PY_OPTS="-python -classic"

We can't bundle code for Python 3 and Python 2 at the same time.

Cheers,
