Insert a single-element container.
Inserts a container into your app that can be used to hold a single element. This allows you to, for example, remove elements at any point, or replace several elements at once (using a child multi-element container).
To insert/replace/clear an element on the returned container, you can use with notation or just call methods directly on the returned object. See examples below.

st.empty() |
Examples
Overwriting elements in-place using with notation:
import streamlit as st import time with st.empty(): for seconds in range(60): st.write(f"⏳ {seconds} seconds have passed") time.sleep(1) st.write("✔️ 1 minute over!")Replacing several elements, then clearing them:
import streamlit as st placeholder = st.empty() # Replace the placeholder with some text: placeholder.text("Hello") # Replace the text with a chart: placeholder.line_chart({"data": [1, 5, 2, 6]}) # Replace the chart with several elements: with placeholder.container(): st.write("This is one element") st.write("This is another") # Clear all those elements: placeholder.empty()
