HI, I have this code : import streamlit as st import random if "var" not in st.session_state: st.session_state["var"] = 0 col3,col4 = st.columns(2) def set_var(value: int): st.session_state["var"] = value def setVal(value:int): set_var(value) # st.rerun() with col4: st.…

I don’t think you need the st.rerun here. Since the order of operations with a button is 1. run the callback 2. rerun the entire page, if you use the on_click method you have commented out and put the random int in the setVal function, does that work? So like this: import streamlit as st import ra…

thanks for your time and efforts, in fact I dont want to pass setVal like this on_click=setVal, i kew it works…but in my real usecase I need to use functions directly I dont have btns…this is the reason why…I tried st.rerun() but it did infinity loop. do you have any idea please ?

Any chance you can share the real use case/full code? I think I’m confused - an infinite loop would usually be a bug, either in your code or potentially in the streamlit rerun
