featuretools.primitives.CumCount¶

class featuretools.primitives.CumCount[source]¶

Calculates the cumulative count.

Description:: Given a list of values, return the cumulative count (or running count). There is no set window, so the count at each point is calculated over all prior values. NaN values are counted.

Examples

>>> cum_count = CumCount()
>>> cum_count([1, 2, 3, 4, None, 5]).tolist()
[1, 2, 3, 4, 5, 6]
