Return true if the *object* argument is an instance of the *classinfo*
argument, or of a (direct, indirect or :term:`virtual <abstract base
class>`) subclass thereof. If *object* is not
an object of the given type, the function always returns false. If
*classinfo* is not a class (type object), it may be a tuple of type objects,
or may recursively contain other such tuples (other sequence types are not
accepted). If *classinfo* is not a type or tuple of types and such tuples,
an object of the given type, the function always returns false.
If *classinfo* is a tuple of type objects (or recursively, other such
tuples), return true if *object* is an instance of any of the types.
If *classinfo* is not a type or tuple of types and such tuples,
a :exc:`TypeError` exception is raised.
