| Boilerpipe Text | Drop all floating point NaN values. The original order of the remaining elements is preserved. Notes A NaN value is not the same as a null value.
To drop null values, use drop_nulls() . Examples >>> df = pl . DataFrame ({ "a" : [ 1.0 , None , 3.0 , float ( "nan" )]}) >>> df . select ( pl . col ( "a" ) . drop_nans ()) shape: (3, 1) ┌──────┐ │ a │ │ --- │ │ f64 │ ╞══════╡ │ 1.0 │ │ null │ │ 3.0 │ └──────┘ |

Expr.drop\_nans() → Self[\[source\]](https://github.com/pola-rs/polars/blob/py-0.20.31/py-polars/polars/expr/expr.py#L1520-L1550)[\#](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.Expr.drop_nans.html#polars.Expr.drop_nans "Link to this definition")
Drop all floating point NaN values.
The original order of the remaining elements is preserved.

[`drop_nulls`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.Expr.drop_nulls.html#polars.Expr.drop_nulls "polars.Expr.drop_nulls")
Notes
A NaN value is not the same as a null value. To drop null values, use [`drop_nulls()`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.Expr.drop_nulls.html#polars.Expr.drop_nulls "polars.Expr.drop_nulls").
Examples
```
>>> df = pl.DataFrame({"a": [1.0, None, 3.0, float("nan")]})
>>> df.select(pl.col("a").drop_nans())
shape: (3, 1)
