class pandas.TimedeltaIndex[source]

Immutable ndarray of timedelta64 data, represented internally as int64, and which can be boxed to timedelta objects


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

Optional timedelta-like data to construct index with

unit: unit of the arg (D,h,m,s,ms,us,ns) denote the unit, optional

which is an integer/float number

freq: a frequency for the index, optional

copy : bool

Make a copy of input ndarray

start : starting value, timedelta-like, optional

If data is None, start is used as the start point in generating regular timedelta data.

periods : int, optional, > 0

Number of periods to generate, if generating index. Takes precedence over end argument

end : end time, timedelta-like, optional

If periods is none, generated index will extend to first conforming time on or just past end argument

closed : string or None, default None

Make the interval closed with respect to the given frequency to the ‘left’, ‘right’, or both sides (None)

name : object

Name to be stored in the index

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 components (days, hours, minutes, seconds, milliseconds, microseconds, nanoseconds) of the Timedeltas.
inferred_freq Tries to return a string representing a frequency guess, generated by infer_freq.


to_pytimedelta() Return TimedeltaIndex as object ndarray of datetime.timedelta objects
to_series([index, name]) Create a Series with both index and values equal to the index keys useful with map for returning an indexer based on an index
round(freq, *args, **kwargs) round the data to the specified freq.
floor(freq) floor the data to the specified freq.
ceil(freq) ceil the data to the specified freq.
to_frame([index]) Create a DataFrame with a column containing the Index.
