How to read array list (of byte or Uint16 for example) in python client

[wuzhzn]

Hi all. When I subscribe to the following nodes, I am able to read the list.
PulseSensorIndex is a list of bytes, PulseSensorInterval is a list of UInt16

However, I wish to read individual entry in the list, I tried using the PulseSensorIndex_Node.read_value() method.
I am only able to see value = 0 as seen below. How do I get value = 1 for the first entry in the list?

[Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False), Variant(Value=0, VariantType=<VariantType.Byte: 3>, Dimensions=None, is_array=False)]

Any help would be greatly appreciated!
