 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 ``ClassValue``\ s**
+**Find iterable "ClassValue"s**

 ----------------------
 
-The QL library for Python also supplies classes to specify taint-tracking analyses. The ``Configuration`` class can be overrridden to specify a taint-tracking analysis, by specifying source, sinks, sanitizers adn additional flwo steps. For those analyses that require additional types of taint to be tracked the ``TaintKind`` class can be overridden.
