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