-   A “shelf” is a persistent, dictionary-like object. The difference with “dbm” databases is that the values (not the keys!) in a shelf can be essentially arbitrary Python objects — anything that the pickle module can handle. This includes most class instances, recursive data types, and objects containing lots of shared sub-objects. The keys are ordinary strings.

->>> with shelve.open('mydata') as shelf_file:
-...     shelf_file['cats'] = cats

-
-```python
->>> with shelve.open('mydata') as shelf_file:

-...
-# <class 'shelve.DbfilenameShelf'>
-# ['Zophie', 'Pooka', 'Simon']
-```
-
-Just like dictionaries, `shelf` values have `keys()` and `values()` methods that will return list-like values of the keys and values in the shelf. Since these methods return list-like values instead of true lists, you should pass them to the `list()` function to get them in list form.

-```python
->>> with shelve.open('mydata') as shelf_file:
-...     print(list(shelf_file.keys()))
-...     print(list(shelf_file.values()))
-...
-# ['cats']
-# [['Zophie', 'Pooka', 'Simon']]
