How do I add a emoji in my button?
Hi @Hiba_Fatima 
You should be able to copy+paste your favorite emojis to the label argument for st.button like so:
import streamlit
st.button("Click Me 👈")

I’ve used sites like Get Emoji and Emoji Finder search for emojis.
Here’s a fun, reproducible example where the emoji used in st.button updates with every click. It makes use of Streamlit’s Session State API and callbacks:
import streamlit as st
import random
# callback to update emojis in Session State
# in response to the on_click event
def random_emoji():
st.session_state.emoji = random.choice(emojis)
# initialize emoji as a Session State variable
if "emoji" not in st.session_state:
st.session_state.emoji = "👈"
emojis = ["🐶", "🐱", "🐭", "🐹", "🐰", "🦊", "🐻", "🐼"]
st.button(f"Click Me {st.session_state.emoji}", on_click=random_emoji)

Happy Streamlit’ing!
