Subclass it and define your own visit_XXX methods, where

XXX is the class name you want to visit with these

|
|
|
cv = ConstantVisitor()

cv.visit(node)

Notes:
|
|
|
|
* generic_visit() will be called for AST nodes for which

|
|
* The children of nodes for which a visit_XXX was
|
|
defined will not be visited - if you need this, call

generic_visit() on the node.

You can use:

NodeVisitor.generic_visit(self, node)
