pyspark.pandas.TimedeltaIndex#

class pyspark.pandas.TimedeltaIndex(data=None, unit=None, freq=<no value>, closed=None, dtype=None, copy=False, name=None)[source]#

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

Parameters

dataarray-like (1-dimensional), optional: Optional timedelta-like data to construct index with.
unitunit of the arg (D,h,m,s,ms,us,ns) denote the unit, optional: Which is an integer/float number.
freqstr 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.
copybool: Make a copy of input ndarray.
nameobject: Name to be stored in the index.

Examples

>>> from datetime import timedelta
>>> ps.TimedeltaIndex([timedelta(1), timedelta(microseconds=2)])
... 
TimedeltaIndex(['1 days 00:00:00', '0 days 00:00:00.000002'],
dtype='timedelta64[ns]', freq=None)

From an Series:

>>> s = ps.Series([timedelta(1), timedelta(microseconds=2)], index=[10, 20])
>>> ps.TimedeltaIndex(s)
... 
TimedeltaIndex(['1 days 00:00:00', '0 days 00:00:00.000002'],
dtype='timedelta64[ns]', freq=None)

From an Index:

>>> idx = ps.TimedeltaIndex([timedelta(1), timedelta(microseconds=2)])
>>> ps.TimedeltaIndex(idx)
... 
TimedeltaIndex(['1 days 00:00:00', '0 days 00:00:00.000002'],
dtype='timedelta64[ns]', freq=None)
