# Default Get

#### Sourcery refactoring id: `default-get`

#### Description:

Simplify dictionary access by using the default `get` method

#### Before:

```python
def pick_hat(available_hats: Dict[Label, Hat]):
    if self.favourite_hat in available_hats:
        hat_to_wear = available_hats[self.favourite_hat]
    else:
        hat_to_wear = NO_HAT
    return hat_to_wear
```

#### After:

```python
def pick_hat(available_hats: Dict[Label, Hat]):
    hat_to_wear = available_hats.get(self.favourite_hat, NO_HAT)
    return hat_to_wear
```

#### Explanation:

We often want to pick something from a dictionary if the key is present, or use
a default value if it isn't.

A useful shortcut is that Python dictionaries have a `get()` method which lets
you set a default value using the second parameter.

This has slimmed the code down and removed some duplication. A point to note is
that if you don't pass in a default value to `get()` it will use `None`.
