>>> lf = pl.LazyFrame( ... { ... "foo": [1, None, 9, 10], ... "bar": [6, 7, 9, None], ... "baz": [1, None, None, 9], ... } ... ) >>> lf.interpolate().collect() shape: (4, 3) ┌──────┬──────┬──────────┐ │ foo ┆ bar ┆ baz │ │ --- ┆ --- ┆ --- │ │ f64 ┆ f64 ┆ f64 │ ╞══════╪══════╪══════════╡ │ 1.0 ┆ 6.0 ┆ 1.0 │ │ 5.0 ┆ 7.0 ┆ 3.666667 │ │ 9.0 ┆ 9.0 ┆ 6.333333 │ │ 10.0 ┆ null ┆ 9.0 │ └──────┴──────┴──────────┘
