# Measure.folder

<span id="atoti.Measure.folder" />

> *property* Measure.folder: [str](https://docs.python.org/3/library/stdtypes.html#str) | [None](https://docs.python.org/3/library/constants.html#None)

Folder of the measure.

Folders can be used to group measures in the **Data model** UI component.

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> df = pd.DataFrame(
...     columns=["Product", "Price"],
...     data=[
...         ("phone", 600.0),
...         ("headset", 80.0),
...         ("watch", 250.0),
...     ],
... )
>>> table = session.read_pandas(df, keys={"Product"}, table_name="Example")
>>> cube = session.create_cube(table)
>>> measure = cube.measures["Price.SUM"]
```

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> print(measure.folder)
None
```

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> measure.folder = "Prices"
>>> print(measure.folder)
Prices
```

By convention, the `\` separator denotes nesting:

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> measure.folder = r"some\\sub\folder"
>>> print(measure.folder)
some\\sub\folder
```

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> del measure.folder
>>> print(measure.folder)
None
```
