# turicreate.SArray.where¶

classmethod SArray.where(condition, istrue, isfalse, dtype=None)

Selects elements from either istrue or isfalse depending on the value of the condition SArray.

Parameters: condition : SArray An SArray of values such that for each value, if non-zero, yields a value from istrue, otherwise from isfalse. istrue : SArray or constant The elements selected if condition is true. If istrue is an SArray, this must be of the same length as condition. isfalse : SArray or constant The elements selected if condition is false. If istrue is an SArray, this must be of the same length as condition. dtype : type The type of result SArray. This is required if both istrue and isfalse are constants of ambiguous types.

Examples

Returns an SArray with the same values as g with values above 10 clipped to 10

>>> g = SArray([6,7,8,9,10,11,12,13])
>>> SArray.where(g > 10, 10, g)
dtype: int
Rows: 8
[6, 7, 8, 9, 10, 10, 10, 10]


Returns an SArray with the same values as g with values below 10 clipped to 10

>>> SArray.where(g > 10, g, 10)
dtype: int
Rows: 8
[10, 10, 10, 10, 10, 11, 12, 13]


Returns an SArray with the same values of g with all values == 1 replaced by None

>>> g = SArray([1,2,3,4,1,2,3,4])
>>> SArray.where(g == 1, None, g)
dtype: int
Rows: 8
[None, 2, 3, 4, None, 2, 3, 4]


Returns an SArray with the same values of g, but with each missing value replaced by its corresponding element in replace_none

>>> g = SArray([1,2,None,None])
>>> replace_none = SArray([3,3,2,2])
>>> SArray.where(g != None, g, replace_none)
dtype: int
Rows: 4
[1, 2, 2, 2]
