Although you can achieve the same result using either one, `dict.get()` is usually preferred, as it accepts a second argument which acts as the default value shall the key not exist in the given dictionary. Due to this property, `dict.get()` will always return a value, whereas `dict[key]` will raise a `KeyError` if the given key is missing. ```py a = { 'max': 200 } b = { 'min': 100, 'max': 250 } c = { 'min': 50 } a['min'] + b['min'] + c['min'] # throws KeyError a.get('min', 0) + b.get('min', 0) + c.get('min', 0) # 150 ```
