nimble.fill.constant(vector, match, constantValue)

Fill matched values with a constant value.

Parameters:

  • vector (nimble point or feature) – A nimble Base object containing one point or feature.

  • match (value or function) –

    • value - The value which should be filled if it occurs in the data.

    • function - Input a value and return True if that value should be filled. Nimble offers common use-case functions in its match module.

  • constantValue (value) – The value which will replace any matching values.

Returns:

list – The vector values with the constantValue replacing the match values.

Examples

Match a value.

>>> lst = [1, 'na', 3, 'na', 5]
>>> X = nimble.data(lst)
>>> constant(X, 'na', 0)
<DataFrame 1pt x 5ft
     0  1  2  3  4
   ┌──────────────
 0 │ 1  0  3  0  5

Match using a function from nimble’s match module.

>>> from nimble import match
>>> lst = [1, 0, 3, 0, 5]
>>> X = nimble.data(lst)
>>> constant(X, match.zero, 99)
<Matrix 1pt x 5ft
     0  1   2  3   4
