featuretools.primitives.CountInsideRange#

class featuretools.primitives.CountInsideRange(lower=0, upper=1, skipna=True)[source]#

确定落在某个范围内的数值数量.

Parameters:

  • lower (float) – 范围的下限（包含）.默认为0.

  • upper (float) – 范围的上限（包含）.默认为1.

  • skipna (bool) – 如果为False,x中的任何值为NaN,则结果将为NaN.如果为True,则跳过`nan`值. 默认为True.

Examples

>>> count_inside_range = CountInsideRange(lower=1.5, upper=3.6)
>>> count_inside_range([1, 2, 3, 4, 5])
2

NaN值的处理方式可以控制.

>>> count_inside_range_skipna = CountInsideRange(skipna=False)
>>> count_inside_range_skipna([1, 2, 3, 4, 5, None])
nan
