# Polars dataframes

In this notebook we make sure that our test [Polars](https://www.pola.rs/)
dataframes are displayed nicely with the default `itables` settings.

```{code-cell} ipython3
import polars as pl

import itables

dict_of_test_dfs = itables.sample_polars_dfs.get_dict_of_test_dfs()
itables.init_notebook_mode()
```

## empty

```{code-cell} ipython3
itables.show(dict_of_test_dfs["empty"])
```

## No rows

```{code-cell} ipython3
itables.show(dict_of_test_dfs["no_rows"])
```

## bool

```{code-cell} ipython3
itables.show(dict_of_test_dfs["bool"])
```

## Nullable boolean

```{code-cell} ipython3
itables.show(dict_of_test_dfs["nullable_boolean"])
```

## int

```{code-cell} ipython3
itables.show(dict_of_test_dfs["int"])
```

## Nullable integer

```{code-cell} ipython3
itables.show(dict_of_test_dfs["nullable_int"])
```

## float

```{code-cell} ipython3
itables.show(dict_of_test_dfs["float"])
```

## float_types

```{code-cell} ipython3
itables.show(dict_of_test_dfs["float_types"])
```

## Ordered floats

```{code-cell} ipython3
itables.show(
    pl.DataFrame(
        {"float": [float("nan"), float("inf")] + [float(x) for x in range(18)]}
    ),
    order=[[0, "asc"]],
)
```

## str

```{code-cell} ipython3
itables.show(dict_of_test_dfs["str"])
```

## time

```{code-cell} ipython3
itables.show(dict_of_test_dfs["time"])
```

## ordered_categories

```{code-cell} ipython3
itables.show(dict_of_test_dfs["ordered_categories"])
```

## countries

```{code-cell} ipython3
:tags: [full-width]

itables.show(dict_of_test_dfs["countries"])
```

## int_float_str

```{code-cell} ipython3
itables.show(dict_of_test_dfs["int_float_str"])
```

## wide

```{code-cell} ipython3
:tags: [full-width]

itables.show(dict_of_test_dfs["wide"], maxBytes=100000, maxColumns=100)
```

## long_column_names

```{code-cell} ipython3
:tags: [full-width]

itables.show(dict_of_test_dfs["long_column_names"])
```

## big_integers

```{code-cell} ipython3
itables.show(dict_of_test_dfs["big_integers"])
```
