1 | (1 (2 (3 4 5 6 7 8) (9 10 (11 12)))) |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | class Node: def __init__(self, name, parent=None): self.name = name self.parent = parent self.children = [] if parent: self.parent.children.append(self) def __repr__(self): if self.children == []: return self.name return '('+self.name + ' ' + ' '.join(repr(c) for c in self.children)+')' # create nodes for tree n1 = Node('1') n2 = Node('2', n1) n3 = Node('3', n2) n4 = Node('4', n2) n5 = Node('5', n2) n6 = Node('6', n2) n7 = Node('7', n2) n8 = Node('8', n2) n9 = Node('9', n1) n10 = Node('10', n1) n11 = Node('11', n10) n12 = Node('12', n10) # add children to their parents n1.children = [n2, n9, n10] n2.children = [n3, n4, n5, n6, n7, n8] n10.children = [n11, n12] # print the tree print(repr(n1)) |
Running the following program:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | class Node: def __init__(self, name, parent=None): self.name = name self.parent = parent self.children = [] if parent: self.parent.children.append(self) def __repr__(self): if self.children == []: return self.name return '('+self.name + ' ' + ' '.join(repr(c) for c in self.children)+')' # create nodes for tree n1 = Node('1') n2 = Node('2', n1) n3 = Node('3', n2) n4 = Node('4', n2) n5 = Node('5', n2) n6 = Node('6', n2) n7 = Node('7', n2) n8 = Node('8', n2) n9 = Node('9', n1) n10 = Node('10', n1) n11 = Node('11', n10) n12 = Node('12', n10) # add children to their parents n1.children = [n2, n9, n10] n2.children = [n3, n4, n5, n6, n7, n8] n10.children = [n11, n12] # print the tree print(repr(n1)) |
(1 (2 3 4 5 6 7 8) 9 (10 11 12))
Testing if the previous output contains the string (1 (2 (3 4 5 6) (7 8)) (9 10 (11 12)))
: False
