pandas.Series.sparse.density#

Series.sparse.density[source]#

The percent of non- fill_value points, as decimal.

This is calculated as the number of non-fill-value points divided by the total length of the array. A density of 1.0 means no values are the fill value, while 0.0 means all values are the fill value.

>>> s = SparseArray([0, 0, 1, 1, 1], fill_value=0)
>>> s.density
