polars.Series.var# Series.var(ddof: int = 1) → float | None[source]# Get variance of this Series. Parameters: ddof“Delta Degrees of Freedom”: the divisor used in the calculation is N - ddof, where N represents the number of elements. By default ddof is 1. Examples >>> s = pl.Series("a", [1, 2, 3]) >>> s.var() 1.0
