Source

pub fn replace( &self, old_value: Expr, new_value: Expr, subset: Option<Vec<&str>>, ) -> Result<DataFrame, PolarsError>

Replace values in columns. PySpark na.replace(to_replace, value, subset=None).

Source

pub fn drop( &self, subset: Option<Vec<&str>>, how: &str, thresh: Option<usize>, ) -> Result<DataFrame, PolarsError>
