Django中是否存在如何获取数据（Laravel）的辅助函数？

data_get函数使用“点”表示法从嵌套数组或对象中检索值：

$data = ['products' => ['desk' => ['price' => 100]]];

$price = data_get($data, 'products.desk.price');

// 100

有关详细信息，请参见

我执行此功能：

def get_data(data, dot_path, default=None):
    arr_paths = dot_path.split('.')
    result = data

    for path in arr_paths:
        try:
            if isinstance(result, (dict, list, tuple)):
                result = result[path]
            else:
                result = None
        except KeyError as e:
            result = None

    if not result:
        result = default

return result
