Type-inference classes
----------------------
The QL library for Python also supplies some classes for accessing the inferred types of values. The classes ``Object`` and ``ClassObject`` allow you to query the possible classes that an expression may have at runtime. For example, which ``ClassObjects`` are iterable can be determined using the query:
The QL library for Python also supplies some classes for accessing the inferred types of values. The classes ``Value`` and ``ClassValue`` allow you to query the possible classes that an expression may have at runtime. For example, which ``ClassValue``\ s are iterable can be determined using the query:
**Find iterable ``ClassObjects``**
**Find iterable ``ClassValue``\ s**
.. code-block:: ql
import python
from ClassObject cls
from ClassValue cls
where cls.hasAttribute("__iter__")
select cls
