Signature de la fonction datetime_data

Description

datetime_data.__doc__

datetime_data(dtype, /)

    Get information about the step size of a date or time type.

    The returned tuple can be passed as the second argument of `numpy.datetime64` and
    `numpy.timedelta64`.

    Parameters
    ----------
    dtype : dtype
        The dtype object, which must be a `datetime64` or `timedelta64` type.

    Returns
    -------
    unit : str
        The :ref:`datetime unit <arrays.dtypes.dateunits>` on which this dtype
        is based.
    count : int
        The number of base units in a step.

    Examples
    --------
    >>> dt_25s = np.dtype('timedelta64[25s]')
    >>> np.datetime_data(dt_25s)
    ('s', 25)
    >>> np.array(10, dt_25s).astype('timedelta64[s]')
    array(250, dtype='timedelta64[s]')

    The result can be used to construct a datetime that uses the same units
    as a timedelta

    >>> np.datetime64('2010', np.datetime_data(dt_25s))
    numpy.datetime64('2010-01-01T00:00:00','25s')
