Hi folks,

newbie alert.

I want to have a binary tree with a single integer value at each node. I'm looking at BinaryTree() but this seems to have the structure of a tree but without values!!!

Please point me in the right direction. I don't mind creating a class from scratch if I can just make a start.

Thanks Joe

You should have a look at LabelledBinaryTree

sage: t1 = LabelledBinaryTree([None, None], label=3)
sage: t2 = LabelledBinaryTree([None, None], label=4)
sage: t = LabelledBinaryTree([t1,t2], label=-2)
sage: t
-2[3[., .], 4[., .]]

And easier to read

sage: ascii_art(t)
  -2
 /  \
3    4
