Give me a the Python code you requested given the following:
Complete the below
def deprecated_call(func=None, *args, **kwargs):

    ''''context manager that can be used to ensure a block of code triggers a
    ``DeprecationWarning`` or ``PendingDeprecationWarning``::
    >>> import warnings
    >>> def api_call_v2():
    ...     warnings.warn(\'use v3 of this api\', DeprecationWarning)
    ...     return 200
    >>> with deprecated_call():
    ...    assert api_call_v2() == 200
    ``deprecated_call`` can also be used by passing a function and ``*args`` and ``*kwargs``,
    in which case it will ensure calling ``func(*args, **kwargs)`` produces one of the warnings
    types above.'
