numpy.datetime_data — NumPy v1.15 Manual (original) (raw)
numpy. datetime_data(dtype, /)¶
Get information about the step size of a date or time type.
The returned tuple can be passed as the second argument of datetime64 andtimedelta64.
| Parameters: | dtype : dtype The dtype object, which must be a datetime64 or timedelta64 type. |
|---|---|
| Returns: | unit : str The datetime unit on which this dtype is based. count : int The number of base units in a step. |
Examples
dt_25s = np.dtype('timedelta64[25s]') np.datetime_data(dt_25s) ('s', 25) np.array(10, dt_25s).astype('timedelta64[s]') array(250, dtype='timedelta64[s]')
The result can be used to construct a datetime that uses the same units as a timedelta:
np.datetime64('2010', np.datetime_data(dt_25s))
numpy.datetime64(‘2010-01-01T00:00:00’,’25s’)
