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]
