#  polars.LazyFrame.interpolate  #

LazyFrame.  interpolate  (  )  →  Self  [ [source]  ](https://github.com/pola-
rs/polars/blob/main/py-polars/polars/lazyframe/frame.py#L5720-L5746) #

    

Interpolate intermediate values. The interpolation method is linear.

Examples

    
    
    >>> lf = pl.LazyFrame(
    ...     {
    ...         "foo": [1, None, 9, 10],
    ...         "bar": [6, 7, 9, None],
    ...         "baz": [1, None, None, 9],
    ...     }
    ... )
    >>> lf.interpolate().collect()
    shape: (4, 3)
