01_todo_app makes "{}" appear instead of a todo

Fresh clone.
create venv with python 3.10
pip install -r requirments.txt
python main.py

This is the result of typing in "hello" into the box and clicking add, 3 times. Each time, another {} is added to the list of {}'s

Start with main.py and reproduce the issue using the setup commands in the report: create a Python 3.10 environment, install requirements, run the app, and add "hello" three times. Trace how the submitted todo is added and rendered in the list. Done means each added todo displays its text instead of {}.
