[python-sybase] How to interpret the cursor.rowcount?

I would guess it's been done to improve compliance with the Python
Database API Specification 2.0, which has the following to say about
rowcount:

    This read-only attribute specifies the number of rows that the last
    executeXXX() produced (for DQL statements like select) or affected
    (for DML statements like update or insert).

    The attribute is -1 in case no executeXXX() has been performed on
    the cursor or the rowcount of the last operation is not determinable
    by the interface.[7]
