Changing text of button

[minhanh29]

I used session_state to replace the whole button. Here is how I switch between 2 buttons:

    myKey = 'my_key'
    if myKey not in st.session_state:
        st.session_state[myKey] = False

    if st.session_state[myKey]:
        myBtn = st.sidebar.button('Button 1')
        st.session_state[myKey] = False
    else:
        myBtn = st.sidebar.button('Button 2')
        st.session_state[myKey] = True

You can use integer instead of boolean to have more cases.
