# This seems to be a common issue amongst new Streamlit users, so I wrote a mini-tutorial app to explain how widgets 
# are used with initialized values and how to make them stick using session state and callbacks.
# 
# There are three ways:
#
# (1) The most basic where the initial value is not given but the widget is always reset, 
# (2) Where it’s initialized but there are issues getting the return value to stick, and finally 
# (3) Overcoming all issues with session state and callbacks.
