Yields the nodes in the tree in preorder.
Returns the Python source code representation of the tree.
Like ast.dump() but with a more readable return value, making the output actually useful for debugging purposes.
Returns True, if the node could be a target for example in an assignment statement ignoring the expression contexts.
Given a node that could be a target, sets the .ctx attribute to ast.Store instances as appropriate.
