Check out the 'types' module too.  That is good for built-in types
which, in CPython but not Jython, are different from class instances.
The isInstance function is better because it works with classes too.
The only problem with it is I don't know what object to pass in as the
"class" of the built-in types.  (Also it doesn't seem to be a built-in
function in Jython)
