-==========================

-.. note::
-
-   Support for generator-based coroutines is **deprecated** and
-   is scheduled for removal in Python 3.10.
-
-Generator-based coroutines predate async/await syntax.  They are
-Python generators that use ``yield from`` expressions to await
-on Futures and other coroutines.
-
-Generator-based coroutines should be decorated with
-:func:`@asyncio.coroutine <asyncio.coroutine>`, although this is not
-enforced.

-   amount of indentation added for each recursive level is specified by *indent*;
-   the default is one.  Other values can cause output to look a little odd, but can
-   make nesting easier to spot.  The number of levels which may be printed is
-   controlled by *depth*; 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.  The desired output width is
-   constrained using the *width* parameter; the default is 80 characters.  If a
