Fonction timedelta_range - module pandas

Signature de la fonction timedelta_range

def timedelta_range(start=None, end=None, periods: 'int | None' = None, freq=None, name=None, closed=None, *, unit: 'str | None' = None) -> 'TimedeltaIndex' 

Description

help(pandas.timedelta_range)

Return a fixed frequency TimedeltaIndex with day as the default.

Parameters
----------
start : str or timedelta-like, default None
    Left bound for generating timedeltas.
end : str or timedelta-like, default None
    Right bound for generating timedeltas.
periods : int, default None
    Number of periods to generate.
freq : str, Timedelta, datetime.timedelta, or DateOffset, default 'D'
    Frequency strings can have multiples, e.g. '5h'.
name : str, default None
    Name of the resulting TimedeltaIndex.
closed : str, default None
    Make the interval closed with respect to the given frequency to
    the 'left', 'right', or both sides (None).
unit : str, default None
    Specify the desired resolution of the result.

    .. versionadded:: 2.0.0

Returns
-------
TimedeltaIndex

Notes
-----
Of the four parameters ``start``, ``end``, ``periods``, and ``freq``,
exactly three must be specified. If ``freq`` is omitted, the resulting
``TimedeltaIndex`` will have ``periods`` linearly spaced elements between
``start`` and ``end`` (closed on both sides).

To learn more about the frequency strings, please see `this link
<https://pandas.pydata.org/pandas-docs/stable/user_guide/timeseries.html#offset-aliases>`__.

Examples
--------
>>> pd.timedelta_range(start='1 day', periods=4)
TimedeltaIndex(['1 days', '2 days', '3 days', '4 days'],
               dtype='timedelta64[ns]', freq='D')

The ``closed`` parameter specifies which endpoint is included.  The default
behavior is to include both endpoints.

>>> pd.timedelta_range(start='1 day', periods=4, closed='right')
TimedeltaIndex(['2 days', '3 days', '4 days'],
               dtype='timedelta64[ns]', freq='D')

The ``freq`` parameter specifies the frequency of the TimedeltaIndex.
Only fixed frequencies can be passed, non-fixed frequencies such as
'M' (month end) will raise.

>>> pd.timedelta_range(start='1 day', end='2 days', freq='6h')
TimedeltaIndex(['1 days 00:00:00', '1 days 06:00:00', '1 days 12:00:00',
                '1 days 18:00:00', '2 days 00:00:00'],
               dtype='timedelta64[ns]', freq='6h')

Specify ``start``, ``end``, and ``periods``; the frequency is generated
automatically (linearly spaced).

>>> pd.timedelta_range(start='1 day', end='5 days', periods=4)
TimedeltaIndex(['1 days 00:00:00', '2 days 08:00:00', '3 days 16:00:00',
                '5 days 00:00:00'],
               dtype='timedelta64[ns]', freq=None)

**Specify a unit**

>>> pd.timedelta_range("1 Day", periods=3, freq="100000D", unit="s")
TimedeltaIndex(['1 days', '100001 days', '200001 days'],
               dtype='timedelta64[s]', freq='100000D')
