pandas.TimedeltaIndex¶
- class pandas.TimedeltaIndex¶
Immutable ndarray of timedelta64 data, represented internally as int64, and which can be boxed to timedelta objects
Parameters: 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
