Trying to implement trie using a list in Python

Question

Hey, this is my first post here! Therefore, I am trying to implement a trie tree using a list in Python, however I have to face some difficulties. This is my code:

trie_root = []
list = ['to','toe']
for word in list:
if word == "":
    continue
else:
    cur_node = trie_root
    for letter in word:
        if len(cur_node)<1:
            x=[letter]
            cur_node.append(x)
            cur_node=x
        else:
            for i in cur_node:

                if letter == i[0]:
                    x=[i[0:]]
                    cur_node=x

                    break

                else:

                    x=[letter]
                    cur_node.append(x)  # This line inserts the next letter in the trie

                    cur_node = x
                    break
    cur_node.append('$')  # This line terminates the word in the trie

print(trie_root)

However, when I print trie_root, the output is [['t', ['o', '$']]] Where is the "e" missing from the "toe" on the output? How to add it? However, if my list contains words starting with different letters, for example "jar" and "toe", it gives the correct conclusion: [['j', ['a', ['r', '$']]], ['t', ['o', ['e', '$']]]] Thanks for reading!
