#  polars.LazyFrame.quantile  #

LazyFrame.  quantile  (

     _ quantile  :  [ float  ](https://docs.python.org/3/library/functions.html#float "\(in Python v3.12\)") |  Expr  _ , 
     _ interpolation  :  RollingInterpolationMethod  =  'nearest'  _ , 
)  →  Self  [ [source]  ](https://github.com/pola-rs/polars/blob/main/py-
polars/polars/lazyframe/frame.py#L5292-L5326) #

    

Aggregate the columns in the LazyFrame to their quantile value.

Parameters  :

    

**quantile**

    

Quantile between 0.0 and 1.0.

**interpolation** {‘nearest’, ‘higher’, ‘lower’, ‘midpoint’, ‘linear’}

    

Interpolation method.

Examples

    
    
    >>> lf = pl.LazyFrame(
