new(cls, node_or_str, children=None, **prob_kwargs)
Static Method

source code

Overrides: Tree.__new__

init(self, node_or_str, children=None, **prob_kwargs)
(Constructor)

source code

Construct a new tree. This constructor can be called in one of two ways:

Tree(node, children) constructs a new tree with the specified node value and list of children.
Tree(s) constructs a new tree by parsing the string s. It is equivalent to calling the class method Tree.parse(s).

Overrides: Tree.__init__: (inherited documentation)

Overrides: Tree.copy

convert(cls, val)
Class Method

source code

Convert a tree between different subtypes of Tree. cls determines which class will be used to encode the new tree.

Parameters:

val - The tree that should be converted.

Returns:

The new Tree.

Overrides: Tree.convert
