python中的raise用法

    if typ == "block":
        return create_block_manager_from_column_arrays(
            arrays, axes, consolidate=consolidate
        )
    elif typ == "array":
        return ArrayManager(arrays, [index, columns])
    else:
        raise ValueError(f"'typ' needs to be one of {{'block', 'array'}}, got '{typ}'")

raise是抛出异常，和java中的throw一样的作用
