want to create a prefix tree in python (3)
2 ADTs Node and PrefixTree
Looking to create Node class with :
-__contains__(letter) - returns true if the Node has a child corresponding to the letter
-__getitem__(let) - returns the child node corresponding to the letter
-add_sub(tok, value) - adds a child to the node under the given token, also handle the case if a child already exists (it should only change the value of the child)
-remove_sub(let) - removes the child node corresponding to a given letter
this is the ADT:
class Node:
def __init__(self, value = None):
self.subs = {}
self._value = value
self.last = True

PYTHON QUESTION... Building a Binary Tree with extended Binary Search Tree and AVL tree. Create a class called MyTree with the methods __init__(x), getLeft(), getRight(), getData(), insert(x) and getHeight(). Each child should itself be a MyTree object. The height of a leaf node should be zero. The insert(x) method should return the node that occupies the original node's position in the tree. Create a class called MyBST that extends MyTree. Override the method insert(x) to meet the definitions of a...

In PYTHON 3- Implement a subclass (described below) of "Word Guess", a variant of the game Hangman. In this game, a word is first randomly chosen. Initially, the letters in the word are displayed represented by "_”. For example, if the random word is "yellow”, the game initially displays "_ _ _ _ _ _”. Then, each turn, the player guesses a single letter that has yet to be guessed. If the letter is in the secret word, then the...

Task 2: SecretWord class:
Download and save a copy of LinkedLists.py (found at the bottom
of this assignment page on eClass). In this file, you have been
given the complete code for a LinkedList class. Familiarize
yourself with this class, noticing that it uses the Node class from
Task 1 and is almost identical to the SLinkedList class given in
the lectures. However, it also has a complete insert(pos, item)
method (which should be similar to the insert method you...
