# pandas.TimedeltaIndex

class pandas.TimedeltaIndex(data=None, freq=<no_default>, dtype=None, copy=None, name=None)

  Immutable Index of timedelta64 data.

  Represented internally as int64, and scalars returned Timedelta objects.

  Parameters:
    data array-like (1-dimensional), optional

      Optional timedelta-like data to construct index with.

    freq str or pandas offset object, optional

      One of pandas date offset strings or corresponding objects. The string `'infer'` can be passed in order to set the frequency of the index as the inferred frequency upon creation.

    dtype numpy.dtype or str, default None

      Valid `numpy` dtypes are `timedelta64[ns]`, `timedelta64[us]`, `timedelta64[ms]`, and `timedelta64[s]`.

    copy bool, default None

      Whether to copy input data, only relevant for array, Series, and Index inputs (for other input, e.g. a list, a new array is created anyway). Defaults to True for array input and False for Index/Series. Set to False to avoid copying array input at your own risk (if you know the input data won’t be modified elsewhere). Set to True to force copying Series/Index input up front.

    name object

      Name to be stored in the index.

  Attributes

  `days` | Number of days for each element.
  `seconds` | Number of seconds (>= 0 and less than 1 day) for each element.
  `microseconds` | Number of microseconds (>= 0 and less than 1 second) for each element.
  `nanoseconds` | Number of nanoseconds (>= 0 and less than 1 microsecond) for each element.
  `components` | Return a DataFrame of the individual resolution components of the Timedeltas.
  `inferred_freq` | (DEPRECATED) Return the inferred frequency of the index.

  Methods

  `to_pytimedelta`() | Return an ndarray of datetime.timedelta objects.
  `to_series`([index, name]) | Create a Series with both index and values equal to the index keys.
  `round`(freq[, ambiguous, nonexistent]) | Perform round operation on the data to the specified freq.
  `floor`(freq[, ambiguous, nonexistent]) | Perform floor operation on the data to the specified freq.
  `ceil`(freq[, ambiguous, nonexistent]) | Perform ceil operation on the data to the specified freq.
  `to_frame`([index, name]) | Create a DataFrame with a column containing the Index.
  `mean`(*[, skipna, axis]) | Return the mean value of the Array.

  Examples

      >>> pd.TimedeltaIndex(["0 days", "1 days", "2 days", "3 days", "4 days"])
      TimedeltaIndex(['0 days', '1 days', '2 days', '3 days', '4 days'],
                     dtype='timedelta64[us]', freq=None)

  We can also let pandas infer the frequency when possible.

      >>> pd.TimedeltaIndex(np.arange(5) * 24 * 3600 * 1e9, freq="infer")
      TimedeltaIndex(['0 days', '1 days', '2 days', '3 days', '4 days'],
                     dtype='timedelta64[ns]', freq='D')
