[Python 3] wrong answer

I am getting wrong answer against all test cases. I am not understanding why.

#2

@v.a
Can you please send the code?

#3

@v.a
Send it in a cb ide link

@v.a
One error in the code is that you did not add the prefix to the trie if No suggestions were found. It is explicitly mentioned. Please perform that step.

If my answer is able to resolve your doubt, please mark the query as resolved.
