The value is always static

Using Streamlit
1

Dear all,

My problem is when I initialize a new variable called self.items = 0, I would like to increase by 1 every time I imported value completely. But I try to debug with that variable, but it was always set by 0 as initialize

Here is my sample code:

import streamlit as st

class main:
    def __init__(self):
        self.items = 0
        self.run()

    def run(self):
        st.title('Home')
        print(self.items)
        if st.button('Submit'):
            self.items = self.items + 1
        print(self.items)

if __name__ == "__main__":
    main()
