def fetch_data():
    st.session_state.data = pd.DataFrame({

fetch_data()

if "data" not in st.session_state:
    st.session_state.data = None

if st.button("Fetch Data"):
    etch_data()

if st.session_state.data is not None:
    st.write("You can edit the data below:")
    edited_data = st.data_editor(

        num_rows="dynamic",
        key=st.session_state.data_key
    )
