I'm not sure why you make two classes, tree and node.
Isn't the left and right branches in the root trees
themselves? I'd just use one class, not two.

I think you are making a common mistake in OO programming,
which is caused by a background in procedural programming. 
You make one data class (node) and one logic class 
(binary_tree). As Yoda said to Luke Skywalker: "You have 
to unlearn what you have learnt."

The fundamental idea with classes is to encapulate a type
of data together with the operations that operate on that
data in a single class.

Good luck with your programming! Is Python taught at UPSI, 
or is learning it a private initiative?
