featuretools.primitives.MultiplyNumericBoolean

class featuretools.primitives.MultiplyNumericBoolean

对数值列表与布尔值列表进行逐元素乘法运算.

Description:

给定一个数值列表X和一个布尔值列表Y,返回X中对应Y值为True的元素.

Examples

>>> import pandas as pd
>>> multiply_numeric_boolean = MultiplyNumericBoolean()
>>> multiply_numeric_boolean([2, 1, 2], [True, True, False]).tolist()
[2, 1, 0]
>>> multiply_numeric_boolean([2, None, None], [True, True, False]).astype("float64").tolist()
[2.0, nan, nan]
>>> multiply_numeric_boolean([2, 1, 2], pd.Series([True, True, pd.NA], dtype="boolean")).tolist()
[2, 1, <NA>]
