return selected
print(open_restaurants(restaurants))
輸出：
['Fork & Fig']
較短版本：
使用列表理解：
def open_restaurants(restaurants):
return [x['name'] for x in restaurants if 'is_closed' in x and not x["is_closed"]]
print(open_restaurants(restaurants))
使用get()而不是索引：
def open_restaurants(restaurants):
return [x['name'] for x in restaurants if 'name' in x and not x.get('is_closed', True)]
print(open_restaurants(restaurants))

在這里使用列表理解。它只有一行，易于閱讀
open_restaurants = [restaurant.get("name") for restaurant in restaurants if not restaurant.get("is_closed")]
Output: ["Fork & Fig"]

使用filter函數：
def open_restaurants(restaurants): return filter(lambda r: not r['is_closed'], restaurants)
