def name_prefix(self):
"""
The name prefix for converted packages (a string).
The default value of :attr:`name_prefix` depends on
the Python interpreter that's used to run py2deb:
- On Python 2 the default name prefix is ``python``.
- On Python 3 the default name prefix is ``python3``.
- On PyPy_ 2 the default name prefix is ``pypy``.
- On PyPy_ 3 the default name prefix is ``pypy3``.
When one of these default name prefixes is used, converted packages may
conflict with system wide packages provided by Debian / Ubuntu. If this
starts to bite then consider changing the name and installation prefix.
.. versionadded:: 2.0
Before his property became part of the documented and public API in
release 2.0 the setter :func:`set_name_prefix()` was the only
documented interface. The use of this setter is no longer required
but still allowed.
Release 2.0 introduced the alternative default name prefixes
``pypy`` and ``python3``. Before that release the default name
prefix ``python`` was (erroneously) used for all interpreters.
