strings (of arbitrary lengths) or ``None``. Character keys will then be
converted to ordinals.

For example:

.. doctest::

>>> str.maketrans({'a': 'A', 'b': 'Boo', 'c': None})
{97: 'A', 98: 'Boo', 99: None}

If there are two arguments, they must be strings of equal length, and in the
resulting dictionary, each character in *from* will be mapped to the character at
the same position in *to*. If there is a third argument, it must be a string,
whose characters will be mapped to ``None`` in the result.

For example:

.. doctest::

>>> str.maketrans('ab', 'AB', 'c')
{97: 65, 98: 66, 99: None}


.. method:: str.partition(sep, /)
