How do I test in a LibreOffice python macro whether I'm in a Writer or Calc document?

Question

I am working in libreoffice and need a python macro that can insert data into the current document from an external source.
Given that the insert methods are different for a spreadsheet and a document using the UNO API, how do I code the macro to discover whether I am in a writer document or a calc spreadsheet and use the appropriate insert method for the type of document?
