Reshape a pandas DataFrame `df` from long to wide format using the DataFrame `auto_pivot()`
method. Write the one-liner that calls `df.auto_pivot()` with the appropriate arguments.
Proposed solution
`auto_pivot()` is not a standard method in pandas. The correct method for reshaping a DataFrame from long to wide format is `pivot()` or `pivot_table()`.

Here is a one-liner using `pivot()`:

```python
df.pivot(index='index_column', columns='column_to_pivot', values='value_column')
```

If you're using a custom or third-party implementation that defines `auto_pivot()`, you would call it like this:

```python
df.auto_pivot(index='index_column', columns='column_to_pivot', values='value_column')
```

**Note:** Replace the placeholder column names with the actual column names in your DataFrame. If you're unsure about the correct method or need help identifying the right columns, feel free to share more details about your DataFrame structure.
