Hi I have a type defined as follows
CREATE TYPE etag ( ttype int, tvalue text ); And this is used in a col of a table as follows evetag list <frozen <etag> > I have the following value in a file [{ttype: 3 , tvalue: '90A1'}] This gets inserted via COPY command with no issues. However when I try to insert the same via a python program which I am writing. where I prepare and then bind, I get this error while executing TypeError: Received an argument of invalid type for column "evetag". Expected: <class 'cassandra.cqltypes.ListType(UserType(Int32Type, VarcharType))'>, Got: <type 'str'>; (Received a string for a type that expects a sequence) I tried casting the variable in python to list, tuple, but same error.
