Using Streamlit
4

Hey!! I did it using empty() & session run id. Thanks!! But how can I do a reset of all components means the app on each run. Do, I need to change the session key for all components?

import streamlit as st
import st_state_patch
import SessionState


    def main():
    	st.title("Data Categorization")
    	session = SessionState.get(txt = '',run_id=0)
    	controler = st.empty()
    	session.txt = controler.text_area("Paste your data here..")
    	print(controler)
    	print(session.txt)
    	s = st.State() 
    	if not s:
    		s.pressed_first_button = False
    		

    	if st.button("Find Category")  or s.pressed_first_button:
    		session.run_id += 1
    		s.pressed_first_button = True # preserve the info that you hit a button between runs
    		try:
    			if session.txt != '':
    				value = st.selectbox("Agree with result", ["Yes, I agree..", "Nah!! I don't"])
    				if st.button("Submit report"):
    					if value == "Yes, I agree..":
    						st.write('Do this ...')
    						
    					elif value != "Nah!! I don't agree":
    						st.write('Do that ...')
    						controler.text_area("Paste your data here..", key=session.run_id)
    			else:
    				st.write('No content found')
    			
    		except Exception as ex:
    			st.write('Looks like I am having problem connecting my backend')
    			print(ex)
    		

    if __name__ == '__main__':
    	main()
