Accessing Custom Array using asyncua or opcua python from OPC server

[anoop1702]

Hello,
I am new to OPC UA and read most of the documents and issues here. But i am not able to find out How to access Array from OPC Client.
I have 3 problems.

1. If I use Python library opcua then i can not access my node using client.get_node('ns=10;s="192.168.120.2,0,0."p_parameter')
   if my node id contains double quotes opcua throws exception. To solve this i used asyncua then the above part works but i can use get_data_values and some other functions. so is there any way that i can make both work while having access to lower class as well?

2. When i try to use get_value() to access array i get error saying the node attribute does not support this.
   I tried Printing the type(get_value()) it says Class List.
   The array is length of 10 and in each it has array of 18 . ex: arr1[a1[],a2[],a3[],...10]
   Can anyone help me how to access these values?

3. I subscribe to an node after some time it says BadToomanysubscription. What does that means?

any suggestions is much appreciated. Thanks
