 .. class:: PrettyPrinter(indent=1, width=80, depth=None, stream=None, *, \
                          compact=False, sort_dicts=True, underscore_numbers=False)
 
-   Construct a :class:`PrettyPrinter` instance.  This constructor understands
-   several keyword parameters.
-
-   *stream* (default :data:`!sys.stdout`) is a :term:`file-like object` to
-   which the output will be written by calling its :meth:`!write` method.
-   If both *stream* and :data:`!sys.stdout` are ``None``, then
-   :meth:`~PrettyPrinter.pprint` silently returns.
-
-   Other values configure the manner in which nesting of complex data
-   structures is displayed.
-
-   *indent* (default 1) specifies the amount of indentation added for
-   each nesting level.
-
-   *depth* controls the number of nesting levels which may be printed; if
-   the data structure being printed is too deep, the next contained level
-   is replaced by ``...``.  By default, there is no constraint on the
-   depth of the objects being formatted.
-
-   *width* (default 80) specifies the desired maximum number of characters per
-   line in the output. If a structure cannot be formatted within the width
-   constraint, a best effort will be made.
-
-   *compact* impacts the way that long sequences (lists, tuples, sets, etc)
-   are formatted. If *compact* is false (the default) then each item of a
-   sequence will be formatted on a separate line.  If *compact* is true, as
-   many items as will fit within the *width* will be formatted on each output
-   line.
-
-   If *sort_dicts* is true (the default), dictionaries will be formatted with
-   their keys sorted, otherwise they will display in insertion order.
-
-   If *underscore_numbers* is true, integers will be formatted with the
-   ``_`` character for a thousands separator, otherwise underscores are not
-   displayed (the default).

 The following methods provide the implementations for the corresponding

 more efficient since new :class:`PrettyPrinter` objects don't need to be
