- At the popup window, click `Import Settings from VCS`. Wait a few seconds. 
  - If the error says "Context Parameter 'Branch' missing", it's ok. Click into the error and add a context parameter `Branch` with value `myTestBranch`. Go back and it automatically reloads.
  - If there are any errors, read the error and fix your code.

`dict`를 선언하려면 컴마로 구분된 2개의 파라미터가 필요합니다.

첫 번째 매개변수는 `dict`의 키(key)이고,

두 번째 매개변수는  `dict`의 값(value)입니다.

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial008.py!}
```

이 뜻은 아래와 같습니다:

* 변수 `prices`는 `dict`이다:
    * `dict`의 키(key)는 `str`타입이다. (각 아이템의 이름(name))
    * `dict`의 값(value)는 `float`타입이다. (각 아이템의 가격(price))

#### `Optional`
