An array of variants in Python is a list.
But I'm not sure why you think you need one?

So this is basically setting up two lists where
the DataType is an integer and the Data is - in
these cases - a string or an integer.
> lineObj.SetXdata DataType, Data
So if you pass in two Python lists containing:
DataType = [1001,1070]
Data = ["Test_Application", 600]
Does it work?
If not what error do you get? (The full text please)

I don;t think you use an array here. An array in this context expects
a homogenous set of data. You need a mixed set. So a normal list
is most likely construct to use.
Alternatively does comtypes have a mechanism for converting Python
types to VB/COM Variants?
