Hey @amineHY,

Could you provide a bit more information on what you’re trying to do or perhaps a code snippet?

In the snippet below the report stops executing after the exception.

import streamlit as st

slider = st.slider('slider', 0, 100, 25, 1)

raise Exception('error')

st.button('button')

Thank you @Jonathan_Rhone,
Your answer is more then enough, I thought there there is a streamlit way of doing it.
Cheers.

@amineHY: If you want to halt execution without visually showing the exception, an undocumented feature is that you can also throw a StopException (more details) which will also silently halt the script.
