Parameters
----------
explicit : bool, optional
Include outputs from explicit components. Default is True.

When True, display/return output values. Default is True.
prom_name : bool, optional
When True, display/return the promoted name of the variable.
Default is False.
residuals : bool, optional
When True, display/return residual values. Default is False.
residuals_tol : float, optional
If set, limits the output of list_outputs to only variables where
the norm of the resids array is greater than the given 'residuals_tol'.
Default is None.
units : bool, optional
When True, display/return units. Default is False.
shape : bool, optional
When True, display/return the shape of the value. Default is False.
bounds : bool, optional
When True, display/return bounds (lower and upper). Default is False.
scaling : bool, optional
When True, display/return scaling (ref, ref0, and res_ref). Default is False.
desc : bool, optional
When True, display/return description. Default is False.
hierarchical : bool, optional
When True, human readable output shows variables in hierarchical format.
print_arrays : bool, optional
When False, in the columnar display, just display norm of any ndarrays with size > 1.
The norm is surrounded by vertical bars to indicate that it is a norm.
When True, also display full values of the ndarray below the row. Format is affected
by the values set with numpy.set_printoptions
Default is False.
tags : str or list of strs
User defined tags that can be used to filter what gets listed. Only outputs with the
given tags will be listed.
Default is None, which means there will be no filtering based on tags.
includes : str, iter of str, or None
Glob patterns for pathnames to include in the check. Default is None, which
includes all.
excludes : str, iter of str, or None
Glob patterns for pathnames to exclude from the check. Default is None, which
excludes nothing.
list_autoivcs : bool
If True, include auto_ivc outputs in the listing. Defaults to False.
out_stream : file-like
Where to send human readable output. Default is sys.stdout.
Set to None to suppress.
