|
Check whether `key` is a valid boolean indexer.
|
|
Parameters
|
----------
|
key : Any
|
Only list-likes may be considered boolean indexers.
|
All other types are not considered a boolean indexer.
|
For array-like input, boolean ndarrays or ExtensionArrays
|
with ``_is_boolean`` set are considered boolean indexers.
|
|
Returns
|
-------
|
bool
|
Whether `key` is a valid boolean indexer.
|
|
Raises
|
------
|
ValueError
|
When the array is an object-dtype ndarray or ExtensionArray
|
and contains missing values.

Helper function for processing random_state arguments.
|
|
Parameters
|
----------
|
state : int, array-like, BitGenerator, Generator, np.random.RandomState, None.
|
If receives an int, array-like, or BitGenerator, passes to
|
np.random.RandomState() as seed.
|
If receives an np.random RandomState or Generator, just returns that unchanged.
|
If receives `None`, returns np.random.
|
If receives anything else, raises an informative ValueError.
|

Default None.
|
|
Returns
|
-------
|

|
Apply a function ``func`` to object ``obj`` either by passing obj as the
|
first argument to the function or, in the case that the func is a tuple,
|
interpret the first element of the tuple as a function and pass the obj to
|
that function as a keyword argument whose key is the value of the second
|
element of the tuple.
|
|
Parameters
|
----------
|
func : callable or tuple of (callable, str)
|
Function to apply to this object or, alternatively, a
|
``(callable, data_keyword)`` tuple where ``data_keyword`` is a
|
string indicating the keyword of ``callable`` that expects the
|
object.
|
*args : iterable, optional
|
Positional arguments passed into ``func``.
|
**kwargs : dict, optional
|
A dictionary of keyword arguments passed into ``func``.
|
|
Returns
|
