Sanity Tests » __metaclass__ = type boilerplate
|
||
|
|
===============================================
|
||
|
|
|
||
|
|
Most Python files should include the following boilerplate at the top of the file, right after the
|
||
|
|
comment header and ``from __future__ import``:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
__metaclass__ = type
|
||
|
|
|
||
|
|
|
||
|
|
Python 2 has "new-style classes" and "old-style classes" whereas Python 3 only has new-style classes.
|
||
|
|
Adding the ``__metaclass__ = type`` boilerplate makes every class defined in that file into
|
||
|
|
a new-style class as well.
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
from __future__ import absolute_import, division, print_function
|
||
|
|
__metaclass__ = type
|
||
|
|
|
||
|
|
class Foo:
|
||
|
|
# This is a new-style class even on Python 2 because of the __metaclass__
|
||
|
|
pass
