Signature de la fonction to_timedelta

def to_timedelta(arg, unit=None, errors='raise') 

Description

to_timedelta.__doc__

    Convert argument to timedelta.

    Timedeltas are absolute differences in times, expressed in difference
    units (e.g. days, hours, minutes, seconds). This method converts
    an argument from a recognized timedelta format / value into
    a Timedelta type.

    Parameters
    ----------
    arg : str, timedelta, list-like or Series
        The data to be converted to timedelta.

        .. deprecated:: 1.2
            Strings with units 'M', 'Y' and 'y' do not represent
            unambiguous timedelta values and will be removed in a future version

    unit : str, optional
        Denotes the unit of the arg for numeric `arg`. Defaults to ``"ns"``.

        Possible values:

        * 'W'
        * 'D' / 'days' / 'day'
        * 'hours' / 'hour' / 'hr' / 'h'
        * 'm' / 'minute' / 'min' / 'minutes' / 'T'
        * 'S' / 'seconds' / 'sec' / 'second'
        * 'ms' / 'milliseconds' / 'millisecond' / 'milli' / 'millis' / 'L'
        * 'us' / 'microseconds' / 'microsecond' / 'micro' / 'micros' / 'U'
        * 'ns' / 'nanoseconds' / 'nano' / 'nanos' / 'nanosecond' / 'N'

        .. versionchanged:: 1.1.0

           Must not be specified when `arg` context strings and
           ``errors="raise"``.

    errors : {'ignore', 'raise', 'coerce'}, default 'raise'
        - If 'raise', then invalid parsing will raise an exception.
        - If 'coerce', then invalid parsing will be set as NaT.
        - If 'ignore', then invalid parsing will return the input.

    Returns
    -------
    timedelta64 or numpy.array of timedelta64
        Output type returned if parsing succeeded.

    See Also
    --------
    DataFrame.astype : Cast argument to a specified dtype.
    to_datetime : Convert argument to datetime.
    convert_dtypes : Convert dtypes.

    Notes
    -----
    If the precision is higher than nanoseconds, the precision of the duration is
    truncated to nanoseconds for string inputs.

    Examples
    --------
    Parsing a single string to a Timedelta:

    >>> pd.to_timedelta('1 days 06:05:01.00003')
    Timedelta('1 days 06:05:01.000030')
    >>> pd.to_timedelta('15.5us')
    Timedelta('0 days 00:00:00.000015500')

    Parsing a list or array of strings:

    >>> pd.to_timedelta(['1 days 06:05:01.00003', '15.5us', 'nan'])
    TimedeltaIndex(['1 days 06:05:01.000030', '0 days 00:00:00.000015500', NaT],
                   dtype='timedelta64[ns]', freq=None)

    Converting numbers by specifying the `unit` keyword argument:

    >>> pd.to_timedelta(np.arange(5), unit='s')
    TimedeltaIndex(['0 days 00:00:00', '0 days 00:00:01', '0 days 00:00:02',
                    '0 days 00:00:03', '0 days 00:00:04'],
                   dtype='timedelta64[ns]', freq=None)
    >>> pd.to_timedelta(np.arange(5), unit='d')
    TimedeltaIndex(['0 days', '1 days', '2 days', '3 days', '4 days'],
                   dtype='timedelta64[ns]', freq=None)
