This is a message that appears when you have provided a single variable for assignment from a method that supports output arguments and return values:
myvar = surface.ConnectFromFile( "Blinn", "Material Shaders" )
In this case, ConnectFromFile returns both the new shader source and provides the old disconnected shader in the PrevDataSource output argument, so the myvar variable is being interpreted as a tuple by Python.
Use the tuple-style syntax as explained in Getting Output Arguments from Methods.
