featuretools.primitives.MaxConsecutiveZeros#

class featuretools.primitives.MaxConsecutiveZeros(skipna=True)[source]#

确定输入中连续零值的最大数量

Parameters:

skipna (bool) – 忽略输入中的任何 NaN 值.默认为 True.

Examples

>>> max_consecutive_zeros = MaxConsecutiveZeros()
>>> max_consecutive_zeros([1.0, -1.4, 0, 0.0, 0, -4.3])
3

NaN 值可以通过 skipna 参数忽略

>>> max_consecutive_zeros_skipna = MaxConsecutiveZeros(skipna=False)
>>> max_consecutive_zeros_skipna([1.0, -1.4, 0, None, 0.0, -4.3])
1
