Get a slice of this DataFrame.

Parameters  :

    

**offset**

    

Start index. Negative indexing is supported.

**length**

    

Length of the slice. If set to ` None  ` , all rows starting at the offset
will be selected.

Examples

    
    
    >>> lf = pl.LazyFrame(
    ...     {
    ...         "a": ["x", "y", "z"],
    ...         "b": [1, 3, 5],
    ...         "c": [2, 4, 6],
