Method Details

init(self, node_or_str, children=None)
(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)

setitem(self)
(Index assignment operator)

source code

Overrides: Tree.__setitem__

setslice(self)
(Slice assignment operator)

source code

x[i:j]=y

Use of negative indices is not supported.

Overrides: list.__setslice__: (inherited documentation)

delitem(self)
(Index deletion operator)

source code

Overrides: Tree.__delitem__

delslice(self)
(Slice deletion operator)

source code

del x[i:j]

Use of negative indices is not supported.

Overrides: list.__delslice__: (inherited documentation)

iadd(self)

source code

x+=y

Overrides: list.__iadd__: (inherited documentation)

imul(self)

source code

x*=y

Overrides: list.__imul__: (inherited documentation)

append(self, v)

source code

append object to end

Overrides: list.append: (inherited documentation)

extend(self, v)

source code

extend list by appending elements from the iterable

Overrides: list.extend: (inherited documentation)

pop(self, v=None)

source code

remove and return item at index (default last)

Returns: item
Overrides: list.pop: (inherited documentation)

remove(self, v)

source code

remove first occurrence of value

Overrides: list.remove: (inherited documentation)

reverse(self)

source code

reverse *IN PLACE*

Overrides: list.reverse: (inherited documentation)

sort(self)

source code

stable sort *IN PLACE*; cmp(x, y) -> -1, 0, 1

Overrides: list.sort: (inherited documentation)

hash(self)
(Hashing function)

source code

hash(x)

Overrides: list.__hash__: (inherited documentation)

_set_node(self, node)

source code

Set self._node. This will only succeed the first time the node value is set, which should occur in Tree.__init__().

node

Get Method:: _get_node(self)
Set Method:: _set_node(self, node) - Set self._node.
