def mapping_get(
    data: Union[dict, list],
    keys: Iterable,
    default: any = None
) - > any

Retrieves a value from a nested dictionary or list structure using a sequence of keys. This function allows for safe traversal of complex data structures by returning a default value if any key in the path is missing.

Parameters

Name	Type	Description
data	Union[dict, list]	The root mapping or sequence object to be traversed.
keys	Iterable	A sequence of keys or indices representing the path to the desired value.
default	any = None	The value to return if a key is not found or an index is out of range during traversal.

Returns

Type	Description
any	The value found at the end of the key path, or the provided default value if the path is unreachable.
