Définition

class PeriodIndex(DatetimeIndexOpsMixin):

Description _{[extrait de PeriodIndex.__doc__]}

    Immutable ndarray holding ordinal values indicating regular periods in time.

    Index keys are boxed to Period objects which carries the metadata (eg,
    frequency information).

    Parameters
    ----------
    data : array-like (1d int np.ndarray or PeriodArray), optional
        Optional period-like data to construct index with.
    copy : bool
        Make a copy of input ndarray.
    freq : str or period object, optional
        One of pandas period strings or corresponding objects.
    year : int, array, or Series, default None
    month : int, array, or Series, default None
    quarter : int, array, or Series, default None
    day : int, array, or Series, default None
    hour : int, array, or Series, default None
    minute : int, array, or Series, default None
    second : int, array, or Series, default None
    tz : object, default None
        Timezone for converting datetime64 data to Periods.
    dtype : str or PeriodDtype, default None

    Examples
    --------
    >>> idx = pd.PeriodIndex(year=[2000, 2002], quarter=[1, 3])
    >>> idx
