# Use Dictionary Items

#### Sourcery refactoring id: `use-dict-items`

#### Description:

Use `dictionary.items()` in `for` loops to access both key and value at same
time

#### Before:

```python
hats_by_colour = {"blue": ["panama", "baseball_cap"]}
for hat_colour in hats_by_colour:
    hats = hats_by_colour[hat_colour]
    if hat_colour in FAVOURITE_COLOURS:
        think_about_wearing(hats)
```

#### After:

```python
hats_by_colour = {"blue": ["panama", "baseball_cap"]}
for hat_colour, hats in hats_by_colour.items():
    if hat_colour in FAVOURITE_COLOURS:
        think_about_wearing(hats)
```

#### Explanation:

When iterating over a dictionary a good tip is that you can use `items()` to let
you access the keys and values at the same time.

This saves us the line that we used to assign to `hats`, incorporating it into
the for loop. The code now reads more naturally, with a touch less duplication.
