Class which provides formatting services useful in implementing functions
2325
similar to the built-in :func:`repr`; size limits for different object types
2426
are added to avoid the generation of representations which are excessively long.

28+
The keyword arguments of the constructor can be used as a shortcut to set the
29+
attributes of the :class:`Repr` instance. Which means that the following
30+
initialization::
31+
32+
aRepr = reprlib.Repr(maxlevel=3)
33+
34+
Is equivalent to::
35+
36+
aRepr = reprlib.Repr()
37+
aRepr.maxlevel = 3
38+
39+
See section `Repr Objects`_ for more information about :class:`Repr`
40+
attributes.

.. versionchanged:: 3.12

Allow attributes to be set via keyword arguments.
