My code never prints “ok”. When the ready button is clicked, the image does disappear though.
I think this might be related to how streamlit continuously refreshes/updates. Not sure how to fix it beyond that though!
I added the form part because I thought that could prevent the autorefreshing. Removing it doesn’t change anything.
hi @catrazzy ,
Did you try using st.write instead of print?
Yes! It doesn’t look like the issue though. I’m planning to look into using session states instead (:
Hi @catrazzy, you could do something like:
import streamlit as st
import time as tm
if "btn_state" not in st.session_state: st.session_state.btn_state = False
st.session_state.btn_state = st.button("Record")
while not st.session_state.btn_state: tm.sleep(0.01)
You could (a) read up on session_state and (b) wrap the “while…” statement with a try-except for any error processing, if needed.
