(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).

Parameters:
